Answer:
w=16, L=20
Step-by-step explanation:Length(L)=w+4
P=72
P=2L+2w
P=2(w+4)+ 2w
P=2w+8+2w
72=4w+8
4w=72-8
4w=64(/4)
w=16
L=16+4=20
Verification: 16+16+20+20=72
32+40=72
72=72 (T)
Answer:
18 and 15 i think
Step-by-step explanation:
Use proportions set up as hotdogs to minutes, then cross multiple 21×m =21m and 6×35 =210 divide by 21 gives you 10 minutes. It would take Mika 10 minutes to eat 35 hot dogs.
What we do first is subtract 11.50 from 16.90.
16.90 - 11.50 = 5.4.
<h3>$5.40 is how much the four drinks cost in total.</h3>
If you wanna find the amount for each drink separately, divide 5.4 by 4.
5.4 / 4 = 1.35.
<h3>Each drink cost $1.35.</h3>
