Answer:
x = 27
Step-by-step explanation:
I'm assuming the equation looks like this:
Here's how to solve for x:
(subtract 5 from both sides)
(Find the GCF of 3 and 9, which is 3. Multiply 2/3 by 3/3. You get 6/9)
(add like terms)
(multiply 9/5 to both sides, which is the same as dividing both sides by 5/9)
x = 27

And the answer to the circumference of a circle with a radius of 177 is approximately:
≈ 1111.56
Answer:
x=12 and y=31
Step-by-step explanation:
First, ( 5x - 7 ) and ( 3x + 17 ) are alternate interior angles, which means they are congruent, or equal:
5x - 7 = 3x + 17
Add 7 to each side:
5x = 3x + 24
Subtract 3x from both sides:
2x = 24
Divide each side by 2:
x = 12
Now we can see that ( 5x - 7 ) and ( 4y + 3 ) are supplementary angles, which means they will add up to 180 degrees:
5x - 7 + 4y + 3 = 180
Substitute 12 in for x to solve for y:
5 ( 12 ) - 7 + 4y + 3 = 180
60 - 7 + 4y + 3 = 180
combine like terms:
( 60 + ( -7 ) + 3 ) + 4y = 180
56 + 4y = 180
Subtract 56 from each side:
4y = 124
Divide each side by 4:
y = 31
Answer:
-8x^3+4xy
Step-by-step explanation:
-4x·2x^2
Multiply the like terms
-8x^3
Two negatives equal a positive so
-4x(-y)
=+4xy
Therefor the answer is:
-8x^3+4xy
