190 = x + 2(x+20)
190 = x + 2x + 40
190 = 3x + 40
190 - 40 = 150
150/3 = 50
x = 50
190 = 50 + 2(50 + 20)
one side of the width (the "short side", as it says) is the barn, so you don't count that because its only asking for the fencing. the length (which would be the long side, which implies that theres only one short side, if that confused you at all) is 20m longer. we figured out that 50m is the width so if both sides are 20m longer, the dimensions of the fencing would be:
50m + 70m + 70m
<u>Answer:</u>
For 500 minutes, the costs of the two plans are equal.
<u>Step-by-step explanation:</u>
Let t be the time of calls in minutes; and
c be the cost of the monthly plan.
<u>1st plan:</u>
<u>2nd plan:</u>
Setting the monthly costs equal to each other to get:
when call minutes , then the cost of the plans are:
1st plan:
2nd plan:
Answer:
The answer is C. The slope is 3 and y-intercept is (0,-1(
I think it’s 84 you multiply 14 and 12 then divide by 2 since it is a triangular prism
Answer:
= -5 - 1/5
0r
-5 - 0.2
Step-by-step explanation:
Volume of a rectangular prism = area of base x height
-5 - 1 = 5x + 5 x area of the base
to determine the area of the base, divide both sides of the equation by (5x + 5)
area of the base = (-5 - 1) / (5x + 5)
= -5 - 1/5
0r
-5 - 0.2
