Solve 4(x + 2) = 20

KiRa [710]

Answer:

x = 3

Explanation:

$\sf 4(x + 2) = 20$

$\sf 4x + 8 = 20$

$\sf 4x = 20 - 8$

$\sf 4x = 12$

$\sf x = \frac{12}{4}$

$\sf x = 3$

check:

4(x + 2) = 20

4(3 + 2) = 20

4(5) = 20

20 = 20

Hence proved x = 3

David ate 80 blueberries in one hour. How many did he eat in fifteen minutes?

Firlakuza [10]

All we have to do is divide how many blueberries he ate in an hour (80) by how many times 15 minutes is in 1 hour (4)

80 ÷ 4 = 20

We can check our work by multiplying 20 by 4

20 x 4 = 80

Therefore, David ate 20 blueberries in 15 minutes

Hope this helps you!

mixas84 [53]

Answer:

LCM(9, -1, -1, +2, +2, +2) = 2×3^2 = 18

9 = 32

-1 = -1

+2 = 2

LCM = 2×3^2 = 18

18 / 9 = 2

18 / -1 = -18
