Simplifies the problem, you divide by a value which if plugged into x would equal 0. One example is dividing by (x-1) as x=1 results in 0
1300 = 1000 (1.08)^t
1.3 = (1.08)^t
log base 1.08 (1.3) = t
3.41 = t
36x34= 1224cm²
(36-4)x(34-4)= 32x30= 960cm²
Area of frame= 1224
Area of picture inside frame= 960
So border = 1224-960= 264
ANSWER = 264cm²
X=71°
X-21=50°
X-12=59°
Add all of the angle measurements to equal 180 so the equation would look like x+x-21+x-12=180. Add all like terms and you’ll then get 3x-33=180. Next add 33 on both sides to get x by itself and then you’ll get 3x= 213. Next divide 3 on both sides to isolate x and you’ll get x=71. Substitute all values of x for 71.
Answer: 35x=73.85, comgining moving terms
divide both sides by 0.35
x=211 quarters, which is $52.75 ANSWER
x+5=216 dimes, which is $21.60 ANSWER
That total is $74.35
