Answers

Answer 1
the answer would be B. 4.7x+7.9
Answer 2

Step-by-step explanation:

so we know that

(8.4x+2.9)+(−3.7x+5)= 4.7x+7.9

so we need an equivelant to 4.7x+7.9

A. −4.7x+7.9= -1/10x(47x-79)

B.=4.7x+7.9=1/10x(47x+79)

C.−12.1x+7.9=-1/10x(121x-79)

D.12.1x+7.9=1/10x(121x+79)

So the answer would be B!

There are 5 blue socks in Josh’s drawer. After he removes 3 non-blue socks, the probability to pick a blue sock at random becomes . How 1/7 many non-blue socks were in Josh’s drawer originally?

Answers

Answer: There is 5 non blue sock in Josh's drawer

Step-by-step explanation:

The denominator shows the total of nonblue and blue socks. So there are 7 non-blue and blue socks in the drawer after he removes 3 non blue socks.To find how many non-blue where in the drawer originally you need to find how many non blue are in the draw after removing the three. So you subtract 7 from 5 which gives you 2. So there are 2 non-blue socks in the drawer after removing the three. Now you need to find how many non-blue were there before he removed the three. So add the 3 non blue socks that he removed to the two that were there after which gives you five.

there are 5 non blue socks

The answer to these is if they add to 180 degrees. Since the first question adds to 180 degrees it is a triangle
one of the rules of triangles is that they all add up to 180 degrees. to find out if a shape can be a triangle you add all the angle measurements up to see what they equal. if they equal 180 they are a triangle. if they equal more or less they are not a triangle. so 1. is a triangle 2. is a triangle 3. is not a triangle 4. is a triangle

What is the slope of the linear function represented in
the table?

Answers

answer: 1/7

the formula for slope is rise over run, or y1-y2 divided by x1-x2. we can choose either number as y1 or y2 but it needs to stay consistent with x

so let’s plug in from your table.

0-1 divided by -7 -0
(you could also do 1-0 divided by 0-(-7))

-1/-7 which equals 1/7

so, your slope is 1/7

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
