Y=72 for the first option,as for the second one i don't know. Hope i helped on the first equation though :)
Perimeter = 2(L + W)
2(L + 10) = 50
2L + 20 = 50
2L = 30, L = 15
Solution: the length is 15 inches
Answer:
660
Step-by-step explanation:
Let A = number of buttons in Box A
and B = number of buttons in Box B
We have two conditions:
(1) A + B = 1200
(2) B + 360 = 3(A – 360) Remove parentheses
B + 360 = 3A - 1080 Subtract 360 from each side
(3) B = 3A - 1440 Substitute (3) into (1)
A + 3A - 1440 = 1200 Combine like terms
4A - 1440 = 1200 Add 1440 to each side
4A = 2640 Divide each side by 4
A = 660
If the value is 5 and the equation is
I = 48t
then
I = 48*5 = 240
option B
