Acarpenter makes chairs with slats that run across the back of the chairs as shown. each chair uses 7 slats . he needs to make 24 chairs . how many slats must he make?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .

brainliest is always apprectiated

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
