The product of 9 and the sum of three times a number and 8 is 180. what is the number? a) 4 b) 6 c) 12 eliminate d) 18

A

Step-by-step explanation:

Remark

Remember to read this over a little at a time.

9 *( 3*x + 8) = 180                     Remove the brackets

27x + 72 = 180                          Subtract 72 from both sides.

27x = 180 - 72                           Combine

27x = 108                                   Divide by 27

x = 108/27

x = 4                                          Answer

s + (a + 178) = 2000

step-by-step explanation:

2000 - 178 = 1822

1822 / 2 = 911

911 + 178 = 1089

1089 + 911 = 2000

abha = 1089

shane = 911
