we are given

length =l=7t+1

width =w=5t+8

now, we can use

perimeter of rectangle formula

perimeter=2(l+w)

we can plug l and w

perimeter=2(7t+1+5t+8)

now, we are given

perimeter=162

so, we can set it equal

162=2(7t+1+5t+8)

now, we can solve for t

162=2(12t+9)

we can isolate t on anyone side

162=2*12t+2*9

162=24t+18

24t=144

t=6

so,

t=6ft...............Answer

box A has 4 marbles.box A has 5% of the marbles.what is the total amount of marbles in all four boxes
laila [671]
Box A is 4. 4 is 5% of the total boxes.
5% = 1/20, so multiply whatever number that's 5% of the total by 20 to get the total.
4 x 20 = 80.
There are 80 marbles total.
Hope this helps!
