8.50+23.25+18+10.75 +x /5=14
Multiply both sides by 5.
60.50. + x =70
Subtract 60.50 from both sides
X= 9.50. The other candy bar costs 9.50
Answer:
the final price is $87.84
Fist find the slope. The equation is m=y2-y1/x2-x1. Then use slope point form and select a point. Then use the equation y-y1=m(x-x1). Simplify and isolate y.
Surface Area Formula
A = 2(lw + hl + wh)
l = 3x
w = x
h = x + 1
A = 2( (3x * x) + (3x * (x + 1)) + (x * (x +1)) )
(Simplify)
A = 2(3x^2 + (3x^2 + 3x) + (x^2 + x))
A = 2(7x^2 + 4x)
A = 14x^2 + 8x
FINAL ANSWER: C
first you should try to find the closest multiple of 19 which you should multiply 19 by 5 and get 95. then subtract 97.75-95 which equals 2.75. 2.75 then needs to be divided by the cost per extra minute 0.07 so 2.75 divided by .07 which gets you 39. 39 minutes
