You can write this ratio in two other ways:
7 to 13
7 : 13
Answer:
x=11
Step-by-step explanation:
Add 7 to both sides
-3x+5x=22
combine like terms(-3x and 5x)
2x=22
divide by 2
x=11
Answer:
60 degrees

A triangle adds up to 180 degrees. 180 divided by 3 is 60. The answer is 60 degrees.
Answer:
y = 3x - 9
Step-by-step explanation:
We first need to find the slope (m)
m =
=
=
= 3
y = mx + b
y = 3x + b
(4, 3)
y = 3x + b
3 = 3(4) + b
3 = 12 + b
-12 -12
-9 = b
(1, –6)
y = 3x + b
-6 = 3(1) + b
-6 = 3 + b
-3 -3
-9 = b
y = 3x - 9
To check: (1, –6)
y = 3x - 9
-6 = 3(1) - 9
-6 = 3 - 9
-6 = -6
Hope this helps!
