Answer:
15
Step-by-step explanation:
if EG is equal to 21 and EF is equal to 6, just subtract EF from EG to get the value of FG
Answer:
8/5=x
Step-by-step explanation:
1/2x+12=8x
Subtract 1/2x from both sides
12=15/2x
Multiply 2/15 on both sides
8/5=x
5x-5=-7y
3x+2y=-8
First, you need to rearrange the first equation so it is in the same format as the second one.
5x-5=-7y
Add 5 to both sides
5x-5+5=-7y+5
Add 7y to both sides
5x+7y=-7y+7y+5
So you have 5x+7y=5
Now you need to multiply that equation by 3
3(5x+7y=5)
15x+21y=15
Multiply the second equation by -5
-5(3x+2y=-8)
-15x-10y=40
Now add them together
15x+21y=15
+(-15x-10y=40)
---------------------
11y=55
y=5
Now plug y=5 into one of the original equations and solve for x.
3x+2(5)=-8
3x+10=-8
3x=-8-10
3x=-18
x=-6
To check the solution plug them both into the other equation:
5(-6)-5=-7(5)
-30-5=-35
-35=-35
It checks.
Hope that helps.
Answer:
They would have the same area.
Step-by-step explanation:
The area of a circle = pi x the circumfrence. or pi x the radious squared. so if they had the same circumfrence they would have the same area.
Answer:
Hey there!
We have the absolute value of x is greater than two.
Thus, to solve absolute value inequalities, we want to break the inequality down.
We break this down to
x>2
x<-2
Thus, we don't need to simplify this any further, and have our answer.
Hope this helps :)
