Alexxx [7]

Answer:

D

Step-by-step explanation:

the answer can't be A or C because we know that 8 3/4 rounds to 9

so we have to figure out if 12 11/16 is closer to 12 or 13

anything above 8/16 should round up; therefore, 11/16 should round the 12 to be 13

Solve this equation: 4y + 228 = 352. <br> A. y = 31<br> B. y = – 31<br> C. y = 3<br> D. y = 145
V125BC [204]
To let the variable alone you can follow these steps: 1) subtract 228 from both sides 2) divide both sides by 4. This is the solution: 1) 4y + 228 - 228 = 352 - 228 => 2) 4y = 124 => 3) (4y)/4 = 124/4 => 4) y = 31. Then, <span>the answer is the option A. y = 31. </span>
