Answer:
y = 1.6
Step-by-step explanation:
Step 1: Divide both sides by 8.
8y/8 12.8/8
y=1.6
Multiple both ratios by a least common denominator
the least common denominator for both is 15
multiply the first ratio by 3/3
9/15=9/15
both are equal because when multiplying by the least common denominator you get the same answer
Fourth test mark should be 86
85 + 82 + 75 + 86 = 328
328 divide by 4 (as there are four tests) = 82
The overall answer is d=16.76
If you are looking for just the answer to (0.3D-1.5)/3 than that is 0.1d-05.
I don’t exactly understand what you want me to solve so I gave you two answers.!
A = a^2 = 121
so a = 11
answer
