Answer:
x = 6
Step-by-step explanation:
We can see that the the 32 degree angle plus the equation (9x + 4) is equal to 90 degrees.
We know this because the bottom line is a 180 degree angle, and we can see on the other side that it is a right angle.
If we were to turn that into an equation it would like like this:
(9x + 4) + 32 = 90
Now you just have to solve for x.
9x + 4 + 32 = 90
Combine like terms:
9x + 36 = 90
Subtract 36 from both sides
9x = 54
divide both sides by 9
x = 6
and you are left with the answer.
Answer:
9/4 *(x-2)
Step-by-step explanation:
Replace xa and y in the given function then solve for y
950 is a real number, and it is a rational number since it can be expressed as 950/1. Therefore, it falls into all of the categories expect irrational numbers.
Answer:
-15
Step-by-step explanation:
Given:
Simply plug in and see if the statement is true. If not, isolate x.
Test for truth:
Isolate x in original equation:
- -14+7=x+8
- -14+7-8=x
- -7-8=x
- -15=x
For the first question you just need to add up all the sides. so first add all the x numbers and then add all the plain numbers.
a perimeter is the total length around the shape.
