Step-by-step explanation:
If we let the width be w, then the length is w+3.5.
This means that w(w+3.5)=11
w^2 + 3.5w - 11 = 0
2w^2 + 7w - 22 = 0 (multiply both sides by 2)
(2w+11)(w-2)=0
w = -11/2 or w = 2 (disregard w = -11/2 as distance is positive)
This means that w=2, and thus the length is 2+3.5=5.5
Answer:
205 square ft
Step-by-step explanation:
1. Since his room is 12ft by 15.75ft, we can multiply to find the square ft needed to cover his room.
2. Since his closet is 2ft by 8ft, we can multiply to find the square ft needed to cover his closet.
3. Then, we add them to find how much carpeting is needed total.
4. (12*15.75)+(2*8)=189+16=205
-2 + Y = 8
Y = 10
Plug in Y to the first equation, 10 + 4 = X
X = 14
A) write an equation you can solve to find the cost of one ticket
x=cost of one ticket.
9x+5=104
b)
I have to solve this equation.
1)adding -5 to each side
2) dividing both sides by 9
c)
9x+5=104
1) 9x+5-5=104-5
9x=99
2) 9x/9=99/9
x=11
the cost of each ticket was $11
