Let's use the variable 'p' to represent peaches.
p + 15 + 22 = 57
p + 37 = 57
p = 20
Ethan bought 20 peaches
area = pi * r^2
here, the radius is 2 as its the diameter/2.
so the area is 4pi.
circumference = 2*pi*r.
so the circumference is 4pi as well.
Answer:
Step-by-step explanation:
4.) y=2x
5.) y=5x+8
6.)y= (x/2)-6
Answer:
x = 7
y = -7/2
Step-by-step explanation:
(x+6i)=(3-i)+(4-2yi)
First look at the real parts
x = 3 +4
x = 7
Then look at the imaginary part
6i= -i -2yi
6 = -1-2y
Add 1 to each side
6+1 = -2y
7 = -2y
Divide by -2
7/-2 = y
Let the number be x.
2x-3=55
2x=55-3
2x=52
x=52/2
x=26
