Slope is 0 and the y intercept is 3
the x's are multiply
that is the associative poprety of multiplcation
so
(ab)c=a(bc)
so
(3x10)x8=3x(10x8)
Answer:
44.0 cm.
Step-by-step explanation:
The formula for the circumference of a circle is

So we can substitute 7 for r and 3.14 for pi:
cm
And since we're rounding to the nearest tenth, the answer is 44.0 cm.
Answer:
a =9
b= 28
Step-by-step explanation:
The parts of the ratio must be equal
5:7:a = 20:b:36
How do we get from 5 to 20
We multiply by 4
So multiply the first by 4
5*4:7*4:a*4 = 20:b:36
Ratio 1
5*4 =20 true
Ratio 2
7*4 =b
28 = b
Ratio 3
4a = 36
Divide by 4
4a/4 = 36/4
a = 9
Answer:

Step-by-step explanation:

Subtract 1 from both sides:


Divide both sides by -7:
