Answer:

p>31/60

−3−(−3p+7)>6p+21(1−3p)

Step 1: Simplify both sides of the inequality.

3p−10>−57p+21

Step 2: Add 57p to both sides.

3p−10+57p>−57p+21+57p

60p−10>21

Step 3: Add 10 to both sides.

60p−10+10>21+10

60p>31

Step 4: Divide both sides by 60.

60p

Answer:

A=266CM

Step-by-step explanation:

p=2l + 2w l=2x+1 w=x+5

66=2[2x+1] + 2{x+5] l=2x9 + 1 w=9+5

66=4x+2 + 2x+10 l=18+1 w=14

66=6x+12 l=19

66-12=6x

54=6x A=L x W

x=9 A=19 x 14

A=266CM

Find y so that (-2, y) is a solution to 3x + 5y=8

podryga [215]

Answer:

y = $\frac{14}{5}$

Step-by-step explanation:

Substitute x = - 2 into the equation and solve for y

3(- 2) + 5y = 8, that is

- 6 + 5y = 8 ( add 6 to both sides )

5y = 14 ( divide both sides by 5 )

y = $\frac{14}{5}$
