7 people came back on the motorbike
Answer:
11
Step-by-step explanation:
Subtract 27 by 12 to figure out how many rode in canoes. Then divide by 3 for each canoe which means that there are 4 canoes. On return trip, there are 16 people riding in canoes because there are 4 per canoe, which means that 27 people in total - 16 people in canoes is 11 people riding the motorboat on the way back.

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.
There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget to spend was $4500. How many first class tickets did they buy? How many Coach tickets did they buy? Show your work.
Answers
Answer:
Step-by-step explanation:
Given
There are 9 people going on a trip
They purchased coach tickets =$160
first class tickets =$1180
total budget to spend = $4500
Let coach tickets=X
So first class tickets=9-x
160x+1180(9-x)=4500
160+10620-1180x=4500
160x-1180x=4500-10620
-1020x=-6120
X=6120/1020
X=6
So answer
Coach tickets=X=6
First class tickets=(9-x)

Answer:
a.) The sum of the weights of the two in insects is 0.0031 grams. (0.0031 grams)
b.) The fly is 0.0013 grams heavier than the gnat. (0.0013 grams)
Step-by-step explanation:
2.2 * 10^-3 = 2.2 * 1/1000 which is 2.2/1000.
9 * 10^-4 = 9 * 1/10000 = 9/10000
To add 9/10000 to 2.2/1000 we have to find the common denominator, which will be 10000.
So we do:
2.2/1000 * 10/10 = 22/10000
9/10000 + 22/10000 = 31/10000 = 0.0031.
The sum of the weights of the two in insects is 0.0031 grams.
To find how much heavier the fly is than the gnat we do:
22/10000 - 9/10000 = 13/10000 = 0.0013
The fly is 0.0013 grams heavier than the gnat.

A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.
Answers
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

An accountant charges a fee of $120 to complete a company's taxes. The accountant also charges an additional $40 per hour to complete the taxes. Which of the following equations can be used to describe this problem?
y = 40 + 120x
y = 40 − 120x
y = 120 + 40x
y = 120 − 40x
Answers
Answer:
y = 120+ 40x
Step-by-step explanation:
The $40 is the rate of change meaning that that would be the number that is next to the variable and the 120 is just staying there meaning it does not have a variable.
if accountant also charges an additional $40 per hour to complete the taxes then the equation y = 40 + 120x can be used to describe.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The fixed fee of $120 is represented by the constant term in the equation, and the additional fee of $40 per hour is represented by the coefficient of x.
As the number of hours worked by the accountant increases, the total fee also increases at a rate of $40 per hour, hence the linear equation.
The equation that can be used to describe the accountant's fee is:
y = 120 + 40x
In this equation, y represents the total fee, and x represents the number of hours worked by the accountant.
Hence, if accountant also charges an additional $40 per hour to complete the taxes then the equation y = 40 + 120x can be used to describe.

Answer:
A'(-4, 7) . . . . ending in quadrant 2
check switched coordinates for C', D'
Step-by-step explanation:
The transformations accomplished by rotations are ...
(x, y) ⇒ (-y, x) . . . . . 90° CCW or 270° CW
(x, y) ⇒ (y, -x) . . . . . 90° CW or 270° CCW
(x, y) ⇒ (-x, -y) . . . . 180° (either direction)
You notice that coordinates are switched and one is negated in each of these transformations. I assume that your line "Coordinates after the switch" is intended to lead you through that first step, then "New coordinates after rotation" is intended to be the same set of coordinates with the appropriate sign change.
__
1. A(7, 4) 90° CCW ⇒ (4, 7) ⇒ A'(-4, 7) . . . . ending in quadrant 2
2. B(-8, -1) 180° ⇒ B'(8, 2) . . . . ending in quadrant 1 (correct)
3. C(9, -5) 270° CW ⇒ (-5, 9)* ⇒ C'(5, 9) . . . . ending in quadrant 1
4. D(-6, -11) 90° CW ⇒ (-11, -6)* ⇒ D'(-11, 6) . . . . ending in quadrant 2

Consider the graph of the linear function h(x) = –6 + 2/3x Which quadrant will the graph not go through and why?
Answers
Answer:
II quadrant.
Step-by-step explanation:
Consider given function:
\(h(x)=-6+\dfrac{2}{3}x\)
Here, we have to find the quadrant from which the graph of function is not passing.
For x=0,
\(h(0)=-6+\dfrac{2}{3}(0)=-6\)
Thus, y-intercept is (0,-6).
For h(x)=0,
\(0=-6+\dfrac{2}{3}x\)
\(6=\dfrac{2}{3}x\)
\(18=2x\)
\(9=x\)
Thus, x-intercept is (9,0).
Plot (0,-6) and (9,0) on a coordinate plane and join them by a straight line as shown below.
From the graph it is clear that the graph is not passing through the II quadrant.
Therefore, the graph is not passing through the II quadrant.
