260+(20x) =140+(30x)
x represents the number of months.
subtract 20x from both sides and subtract 140 from both sides
120=10x
divide each side by 10
12=x
So in 12 months, Jamal will have paid the same amount to both shops.
To check your answer, you plug in 12 for x.
260+20(12)=140+30(12)
260+240=140+360
500=500
Hope this helps.
Answer:
If 12 and 14 are both side lengths then we solve for the hypotenuse:
hypotenuse^2 = 12^2 + 14^2
hypotenuse^2 = 144 + 196
hypotenuse^2 = 340
hypotenuse = sq root (340) = 18.4390889146
If hypotenuse = 14, then third side equals:
(3rd side)^2 = 14^2 - 12^2
(3rd side)^2 = 196 -144
(3rd side)^2 = 52
3rd side = sq root (52) = 7.2111025509

Answer:
18.84
Step-by-step explanation:
To find the diameter of an question, multiple the radius by 2, since the radius always covers half of the circular clock. Then multiple 12 x pi = 18.84.
(pi = 3.14)
