zach is 4 years older than twice his sister maya's age. zach is 28 years old.
which expression would you use to represent zach's age?
Answers
Answer:
Lets take:
Z - Zach
M - Maya
Now forming the equation:
Z = 2M+4
Z = 28
Solving:
2M+4 = 28
2M = 24
M = 12
Zach's age is 28; whereas Maya's age is 12.
Answer:
2m + 4 = 28
Step-by-step explanation:
Let m be Maya's age
4 years older than twice his sister Maya's age = 2m + 4 If "4 years older than twice his sister Maya's age" and "Zach is 28 years old" are equal, then this is how you'd write it: 2m + 4 = 28I hope this helps!

Answers
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
\(a=-15b-5\)

The heaviest bag (far right) weighs 4.75 lbs, whereas the lightest bag (far left) weighs 3.25 lbs. As mixed numbers, these would be \(4\frac{3}{4}\) and \(3\frac{1}{4}\). To find how much heavier the 4.75 lb bag is, you must subtract the 2 numbers.
Step 1. Convert each to a complex fraction\(4\frac{3}{4}\) = \(\frac{19}{4}\)
Numerator = (4 x 4) + 3 = 19Denominator = 4 (stays the same)\(3\frac{1}{4}\) = \(\frac{13}{4}\)
Numerator = (3 x 4) + 1 = 13Denominator = 4 (stays the same)Step 2. Subtract fractions like normal\(\frac{19}{4} - \frac{13}{4} =\frac{6}{4}\)
\(\frac{6}{4} =\frac{3}{2}\)

a and are different numbers that are selected from the first 25 whole numbers: 1 through 25.If a is greater than b, what is the smallest value the expression could have?
Answers
Answer:
The smallest value the expression could have is 1.
Step-by-step explanation:
If a and b are different numbers selected from the first 25 whole numbers (1 through 25), and a is greater than b, the smallest value the expression could have is when b is the smallest possible value and a is the next smallest value.
The smallest possible value for b is 1, and a must be greater than b. Therefore, the smallest possible value for a is 2.
So, the smallest value the expression could have is 2 - 1 = 1.

The value of the missing side of the trapezoid will be 6 inches.
What is a trapezoid?A trapezoid is a quadrilateral having two parallel sides and two nonparallel sides. The area of the trapezoid is the space occupied by a quadrilateral having two parallel sides and two nonparallel sides in a two-dimensional plane.
Given that the area of the trapezoid is 21 square inches and the height is 3 inches the other side is 8 inches.
The value of the unknown side is calculated as below:-
Area = [ ( a + b ) / 2 ] x h
21 = [ ( 8 + b ) / 2 ] x 3
7 = ( 8 + b ) / 2
14 = 8 + b
b = 14 - 8
b = 6 inches
Therefore, the value of the missing side of the trapezoid will be 6 inches.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143
