X=7
(15x+3)=108
x=7
if you plug 7 in for x
(15(7)+3) it equals 108
answer is either A or D
I hope this help. but I'm not really sure.
Answer:
22 and 158
Step-by-step explanation:
Supplementary angles add to 180. This is means there is a small and large angle. Adding together, they make 180.
- "the larger angle measures four degrees more than seven times the measure of a smaller angle" is represented as 7x+4.
- "x represents the measure of the smaller angle" is represented as x.
x + 7x+4 =180
8x+4=180
8x=176
x= 22
This is the measure of the smaller angle. The larger angle is 7(22)+4 = 158
Answer:
10 tickets
Step-by-step explanation:
25 + 5x = 35 + 4x
solve for x:
subtract 25 from both sides...
5x = 35 - 25 + 4x
subtract 4x from both sides...
5x - 4x = 10
x = 10, 10 tickets.
Just reflect C and D across the y-axis
C is (-4, -4) so A is (-4, 4)
D is (4, -4) so B is (4, 4)
