30/40 say no, so x/1000 would say no. 1000/40=25, 25*30=750. So, about 750 would dislike it.

Solve the two step equations

disa [49]

Hello!

1) -3x - 4 = 23

-3x = 23 + 4

-3x = 27

x = 27 : (-3)

x = -9

2) x/2 - 12 = -4

x - 24 = -8

x = -8 + 24

x = 16

3) 6a + (-1) = 10

6a - 1 = 10

6a = 10 + 1

6a = 11

a = 11 : 6

a = 11/6

4) -(x + 2) = 12

x + 2 = -12

x = -12 - 2

x = -14

5) 7a + 12 = 10

7a = 10 - 12

7a = -2

a = -2 : 7

a = -2/7

6) -4(a + 2) = 12

a + 2 = -3

a = -3 - 2

a = -5

Good luck! :)

A parallelogram has an area of 300 square kilometers and a height of 20 kilometers. What is the length of the base?

Neko [114]

Answer: the length of the base is 15 kilometers.

Step-by-step explanation:

formula : Area of parrallelogram = Length of base x height

Given: Area of parallelogram = 300 square kilometers

height = 20 kilometers

Substituting values in the formula , we get

300 = Length of base x 20

Length of base = $\frac{300}{20}$

= 15 kilometers

Hence, the length of the base is 15 kilometers.
