20 ÷ 5 = 4
So there are 4 sets of 5 shirts. If there are 3 striped shirts per 5 then
3 x 4 = 12 striped shirts
Hope it helps!
Answer:
The Equation is False.
Step-by-step explanation:
(14+7)=21 + (-1) = 20
The Area is the width<span> times the </span>height<span>: A = w x h;
Then, 64 = w x h;
h = 4 + w;
64 = 4w + w^2;
w^2 + 4w - 64 = 0;
We solve this equation: w1 </span>≈ 6,24 > 0 (okay); w2 ≈ - 10,24 < 0 (not okay);
<span>Finally, h1 </span>≈ 10,24;<span>
</span>
It's impossible for 2 factors of 12 to add up to 16. So there would be no answer to that.
