Answer 1

Answer:

x = -13

Step-by-step explanation:

Equation:

(6x+8)/7 = -10

Multiply both sides by 7:

7* (6x+8)/7 = -10*7

6x+8 = -70

Subtract both sides by 8:

6x + 8 - 8 = -70 - 8

6x = -78

Divide both sides by 6:

6x/6 = -78/6

x = -13

Check answer:

(6*(-13) + 8)/7 = -10

(-78 + 8)/7 = -10

(-70)/7 = -10

-10 = -10

Our answer is correct :)

4 Zahara rides with her dad to her grandmother's house. They travel 159 miles

in 3 hours. Her uncle, Jorge, drives there separately from his home.

a. At what speed does Zahara's dad drive, in miles per hour?

Answers

Based on the distance they covered in the time they did, we can infer that Zahara's dad was driving at 53 miles per hour.

To find the speed, the following formula is used:

= Distance / Time

They travelled 159 miles in 3 hours.

Distance = 159 miles

Time = 3 hours

The speed must be:

= 159/3

= 53 miles per hour

In conclusion, he was going at 53 miles per hour.

fill in the blank to make the two fractions equivalent. 7/9 = ?/27

Answers

Answer: 21

Step-by-step explanation:

To find the missing number you set the two equations as a proportion:

[tex]\frac{7}{9} = \frac{x}{27}[/tex]

To solve for x we cross multiply:

27 × 7 = 189

9 × x = 9x

Set up an equation:

9x = 189

Divide both sides by 9:

x = 21

Miranda lives 8 blocks south of her school. She decides to visit a friend who lives even farther south. She walks south 1 block per minute. Write an equation that shows the relationship between the number of minutes Miranda has been walking, x, and the number of blocks south of school she is, y. y =

Answers

We want to write an function that relates the number of blocks south of school that she is to the number of minutes that she has been walking.

The function is: y = (1 block/minute)*x + 8 blocks

A general linear function is:

y = a*x + b

where a is the slope and b is the y-intercept.

First, we do know that she lives 8 blocks south of her school, so the y-intercept of the linear function will be 8 blocks (the point where she starts).

Now we know that her friend lives farther south, so she moves south, at a velocity of 1 block per minute.

Then the linear function is:

y = (1 block/minute)*x + 8 blocks

What is the equation of the line that has a slope of -4 and passes through (2, -3)

Answers

Answer:

y+3 = -4(x-2)

Step-by-step explanation:

We can use point slope form since we are given a point on the line and a slope,

Point slope form is

(y-y1) = m(x-x1) where m is the slope and (x1,y1) is a point on the line

(y- -3) = -4(x-2)

y+3 = -4(x-2)
