Answer:
6) x = 40.5
8) x = 16.5
Step-by-step explanation:
6) 45/x = 20/18
simplify and cross-multiply to get:
45/x = 10/9
10x = 405
x = 40.5
8) 22/8 = x/6
11/4 = x/6
4x = 66
x = 33/2
x = 16.5
Use substitution
-x + 4 = 1/3x + 8
4 = 4/3x + 8
-4 = 4/3x
x = -4 * 3/4
x = -3
Then plug x into one of the original equations. In this case y = -x + 4 is the easiest.
y = -(-3) + 4
y = 7
Answer:
a rotation about point C
Step-by-step explanation:
I just took the test and I got it right
thank me with a like :P
It started at $37.
It went down $3.
37 - 3 = 34
It went up 1.
34 + 1 = 35
It went down 7.
35 - 7 = 28
It went up 4.
28 + 4 = 32
The price at the end of the day was $32.
