Answer:
w=-1
Step-by-step explanation:
w-6=-4w-11
5w=-5
w=-1
3x + 2y + y - 3x = 180
3y = 180
y = 180/3
y = 60
3x = y - 3x
Let y = 60
3x = 60 - 3x
3x + 3x = 60
6x = 60
x = 60/6
x = 10
Answer: x = 10, y = 60
Answer:
A=SqRt(c^2-b^2)
Step-by-step explanation:
a^2 + b^2 = c^2
rearrange to solve for a^2
a^2= c^2-b^2
take the square root of each side
a= square root (c^2-b^2)
Answer:
5
Step-by-step explanation:
If their average is 6 and there are three numbers in total, the total sum of the three numbers would be:
6×3 = 18
You know that two of them is 6 and 7, so you can find the last number easily.
18-6-7 = 5
Answer:15 pi
Step-by-step explanation:
The scope is 10(r)*2*pi
XPY is 3 quarters of the slope, which equals to 0.75*20*pi=15pi
