Answer:

x = -3; substitute it to the other equation.

2(-3) - 7y = 30

-6 - 7y = 30

-7y = 30 + 6

-7y = 36

y = -36/7

we will not round the number because the question is asking for an improper fraction at its simplest form.

Answer:

5.1

Step-by-step explanation:

2*-3 - 7y =30

-6 + 7y = 30

7y = 30 + 6

y = 36 / 7

i.e. y = 5.1

Find the measure of the missing value in the
kumpel [21]

Answer:

12.6

Step-by-step explanation:

The two left sides have lengths, so this allows you to establish the ratio of the lengths of the sides of the triangles,

left triangle : right triangle

ratio = 25 : 17.5

The bottom sides are also in the same ratio.

ratio = 18 : w

Write a proportion by setting the ratios equal and solve for w.

25/17.5 = 18/w

Cross multiply.

25w = 17.5 * 18

25w = 315

w = 12.6

Answer: 12.6

-4y = 16 <br> identify the slope and y intercept
Shalnov [3]

Answer:

zero slope

y-intercept at y = -4

Step-by-step explanation:

-4y = 16  (divide both sides by -4)

y = 16 / (-4)

y = -4

y = -4 represents a horizontal line that is parallel to the x-axis that crosses the y-axis at y = -4

hence the slope of a horizontal line is zero, and the y-intercept is -4
