HELP PLEASEEEEEEEEEEEEE!
Answer:
3.) x=3
4.) x=11
Step-by-step explanation:
3.) 80= 27x-1
x=3
4.) 5x+5+9x+21= 180
14x+26= 180
x=11
Answer: #3) x= 3. #4) x= 11
Step-by-step explanation:
For #3 these angles are alternate exterior angles. (Opposite sides of the transversal and outside of the parallel lines) Alternate exterior angles are equal, so set these two equal to each other to solve for x. 27x-1 = 80 Add 1 to both sides. 27x = 81. Divide both sides by 27. X = 3. For #4, these angles are same side interior angles. (Same side of the transversal and inside the parallel lines) Same side interior angles sum to 180 degrees. (5x+5) + (9x+21) = 180. Combine like terms. 14x + 26= 180. Subtract 26 from both sides. 14x = 154. Divide both sides by 14. X = 11

of completing the square. What number did Sarah add to
both sides of the equation during the process?
a. -8
b. 16
C. 10
d.-4

Angles 1 and 2 are supplementary.
• The measure of angle 1 is (2x - 3) ◦
• The measure of angle 2 is (-5x + 423) ◦
What is the measure of angle 2?
Answer:
1 = 157°
2 = 23°
Step-by-step explanation:
because the angles are supplementary, their angles will add up to 180°set up the equation (2x-3)+(-5x+423)=180combine like terms to get -3x+420=180subtract 420 from 180 to get -3x=-240divide by three and get x=80now plug in 80 for x in both equationsIf Juan gets 60 problems correct out 75, what percentage did he get correct?

What is the equation of a circle centered at the origin with radius 20
Answer:
we have a rule
(x-h)²+(y-v)²=r²
while h is the x intercept
v is y intercept
r is the radius
so the answer will be
x²+y²=400
or
x²+y²=20²

Step-by-step explanation:
The number of yodelers is twice the number of xylophones, how do I write this in a equation ?
Answer:
X=(Y*2) // Y=(X/2)
Step-by-step explanation:
Xylophones = "X"
Yodelers = "Y"
First Equation: X=(Y*2) essentially just explains that the xylophones is equal to the yodelers times 2
Second Equation: Basically the same thing, but rather than multiplying the yodelers by two, it divides the xylophones in half.

What is the equation in slope-intercept form of the line that passes through (2, 3) and is parallel to the line through (-2, 1) and (7, 1)?
9514 1404 393
Answer:
y = 3
Step-by-step explanation:
The slope formula can be used to find the slope of the parallel line.
m = (y2 -y1)/(x2 -x1)
m = (1 -1)/(7-(-2)) = 0
The line is a horizontal line, so the y-intercept must be chosen to match the y-value of the given point.
y = 3
_____
If you want to see the slope of zero in the slope-intercept form equation, you can write the equation as ...
y = 0x +3
It is pretty unusual to keep 0 terms in an equation. Usually, they are eliminated when the equation is simplified.

In the past month, Frank rented 5 video games and 6 DVDs. The rental price for each video game was 2.10 The rental price for each DVD was 3. 70 What is the total amount that Frank spent on video game and DVD rentals in the past month?
Answer: $32.70
Step-by-step explanation:
Total amount spent on Video game rentals:
= Number of video game rentals * rental price of video game
= 5 * 2.10
= $10.50
Total amount spent on DVD rentals:
= Number of DVD rentals * rental price of DVD
= 6 * 3.70
= $22.20
Total spent on both:
= 10.50 + 22.20
= $32.70
