The measure of an angle is seven times the measure of its supplementary angle. What is the measure of each angle?
Step-by-step explanation:
7x= 180-x
7x+x= 180
8x= 180
x= 22.5
the angle is 22.5
its supplementary angle is 157.5

9514 1404 393
Answer:
A) {( –2, 5), (–3, 3), (6, 4), (–7, –1)}
Step-by-step explanation:
The ordered pairs of an inverse relation are the reverse of the ordered pairs of the original relation.
You will be looking for ordered pairs that have first values the same as the original relation's second values: {-2, -3, 6, -7}. That list is found in choice A.
How many pounds of green tea, worth $40 a pound, should be mixed with herbal tea, worth $50 a pound, to produce 20 pounds of blend worth $42 a pound?
Answer:
840
Step-by-step explanation:
First you have to multiply 42 by 20. Because you have to find the total cost of the whole bag. Then a little guess and check you would get 16 lb of green tea and 4 lb of herbal tea. They both have to equal 20 lbs and $840. Multiply 16 by 40 then 50 by 4 then add them together you will get 840.
Hope this was helpful.

Which of the following rational functions is graphed below?
Answer:
Lets start by looking at the y and x asymptotesX=1 and x=5 Hence we need to look for (x-1) and (x-5)Hence A is your answerFind the solution to the system: y=4x and 3x+2y=55
Answer:
x = 5, y = 20
Step-by-step explanation:
if y = 4x and 3x+2y = 55 then we can subtitude y as x.
We know that y = 4x so we can write 4x wherever we see y.
3x + 2y = 3x + 2(4x) = 55
3x + 8x = 55
11x = 55
x = 5.
And if y = 4x = 4(5)
y = 20

Simplify each expression by using the distributive property and combining like terms.
3 ● (2x - 4) - 4x
Answer:
2x - 12
Step-by-step explanation:
Hello!
So, let's simplify using the distributive property.
Let's look at 3(2x - 4). You want to multiply 3 by every term inside the parentheses.
3*2x = 6x
3*-4= - 12
So now our expression looks like this:
(6x - 12) - 4x
Now we combine like terms. Our only like terms are 6x and -4x.
6x - 4x = 2x. So, our simplified expression is:
2x - 12.
