Kate got the same answer when she solved (3 × 7) + 8 – 1 and 3 × 7 + 8 – 1. which answer option is correct? a. (3 × 7) + 8 − 1 = 28 and 3 × 7 + 8 − 1 = 28 b. (3 × 7) + 8 − 1 = 28 but 3 × 7 + 8 − 1 = 27 c. (3 × 7) + 8 − 1 = 27 but 3 × 7 + 8 − 1 = 28

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
