Answer:
the percent change would be 40 percent
Step-by-step explanation:
think of 10 as a base so like 100 ok and you know if 50 of that is 50 percent 40 would just be forty percent
Answer:
Step-by-step explanation:
a. 3-4x=-7-4x
3=-7. no solution
b. 15 - 2x = -7x
15 = -5x
x=-3. one solution
c. 7y-21=6y-21
y=0
1. -3x+4=-3x+7
4=7
2. 10+2x = 5x+2
8=3x
x=3/8
3. x+5=x+5
Answer:
30 inches
Step-by-step explanation:
The circumference of a circle can be found by using 2
r, or
* d.
Since we are given the circumference of the circle, 30
, you can find the diameter by solving for the diameter (after substituting in the circumference) in the formula for circumference.

To cancel out
you can divide both sides of the equation by pi. Now you have:
30 = d
Therefore the diameter of the circle is 30 inches.
Po ^2 = 6^2 + 8^2
Po^2 = 36 + 64 = 100
So Po = 10
Sin x = 8/po = 8/10= 0.8
Cos y = 6/po = 6/10=0.6
