Answer:
x = 27
Step-by-step explanation:
line AC and DE are parallels, so the extra angle in the triangle would be 2x because they are corresponding angles.
A triangle adds up to 180, so the equation would be 180 = 72 + 2x + 2x
Answer:
7 games
Step-by-step explanation:
<u>First Person:</u>
Fixed Cost of 99.26
Variable Cost of 4.50 per game (program cost)
<u>Second Person:</u>
No Fixed Cost
Variable cost of 18.68 per game (ticket cost)
Now, we let the number of games be "x", so we can write 2 equations for each person. Then we equate and find at what number of games, the amount paid by both person would be same. Shown below:
<u>First Person Equation:</u>
99.26 + 4.50x
<u>Second Person Equation:</u>
18.68x
Now, equate and solve for x:
99.26 + 4.50x = 18.68x
99.26 = 18.68x - 4.50x
99.26 = 14.18x
x = 99.26/14.18
x = 7
So, the answer is 7 games
Answer:
Step-by-step explanation:
Freddie rate of mowing=3/2=1.5 lawns /hr.
Tom's rate of mowimg=2 lawns/hr
so Tom can mow Smith's lawn faster.
Answer:
True.
Step-by-step explanation:
It explains itself right
B^2 - 4ac
(-9)^2 - 4 (2)(9)
= 81 - 72
=9 >0 yet it is a perfect square (3^2 =9)
So , it is 2 real and rational roots
(x-3) ( 2x-3) =0
x = 3 , x = 3/2
