I believe it is a but i will double check and post ok
1.

2.

3. -7/30
4. i believe it is the communitive of multiplication , but not 100% sure
x = -38/9 !!!
27(x+4)=−6
Step 1: Simplify both sides of the equation.
27(x+4)=−6
(27)(x)+(27)(4)=−6 (Distribute)
27x+108=−6
Step 2: Subtract 108 from both sides.
27x+108−108=−6−108
27x=−114
Step 3: Divide both sides by 27.
27x/27=−114/27
x=−389
Question 42 is B because I did the math
