Answer:
12
Step-by-step explanation:
So Josh is 6 years older than kims age and the sum of the ages is less than 31, the greatest number that is less than 31 is 30 so we can use that.
We can make an equation out of this and solve it.
n+(n+6)=30
2n+6=30
2n=24
n=12
12 is the oldest Kim could be.
12+(12+6)=12+18=30.
Answer:64pi
Step-by-step explanation:
Circumference(c)=16pi
Circumference(c)=2 x pi x radius(r)
Substituting we get
16pi=2 x pi x r
Divide both sides by 2pi
16pi/2pi=(2xpixr)/2pi
8=r
Radius(r)=8cm
Area(a)=pi x r^2
a=pi x 8^2
a=64pi
Therefore area of the circle=64pi
Answer:
gold
Step-by-step explanation:
It should be -101. Just plug in 9 into x so it would be like f(9)= 9^2-20. Which equals -101
Answer:
a x (b + c) or a x (b - c)
4 × (11 + 10)
or
4 × (22 - 1)
Step-by-step explanation:
20 + 64 = 84
84 ÷ 4 = 21
21 - 10 = 11
22 - 1 = 21
