Answer:
X=13
Step-by-step explanation:
Answer:
x=13
Step-by-step explanation:
21=8+x
Swap sides so that all variable terms are on the left hand side.
8+x=21
Subtract 8 from both sides.
x=21−8
Subtract 8 from 21 to get 13.
x=13

Answer:
A: -16/3
B: 16/3
C: -6
D: -6
E: 6
Step-by-step explanation:
A would be -16/3 because you multiply -2 time 8 which is 116. And the denominator is 3.
B would be 16/3. It is the same as problem A but there are two negatives which make positive.
C is -6. You just divide -18/3.
D is the exact same as C. It just has parenthesis but the answer is still -6.
E is 6 because there are two negatives which make a positive.
Lin lines the bottom of her first pan with aluminum foil. The area of the rectangular piece of foil is 11 1/4 square inches. Its length is 4 1/2 inches. What is the width of the foil?
Answer: the answer is 2.5
Step-by-step explanation:
Answer:
w= 5/2 inches or 2 1/2 inches
Step-by-step explanation:
area = length × width (w)
45/4 = 9/2 × w
45/4 =9w/2
45×2 = 9w×4
90 = 9w×4
9w= 90/4= 45/2
w= 45/2 × 1/9
w= 5/2 inches or 2 1/2 inches

In 2017 the SAT had a mean score of 1060 with standard deviation of 195 (max score of 1600) while the ACT had a mean of 20.9 with standard deviation of 5.6 (max composite score of 36). Reed and Maria apply to the same college. Maria took the SAT and received a score of 1270 while Reed took the ACT and received a score of 27. Which student performed better in relationship to their peers
Answer:
Due to the higher z-score, Reed performed better in relationship to their peers
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
Whoever had the higher z-score performed better in relation to their peers.
Maria:
Took the SAT, grade 1270, so [tex]X = 1270[/tex]
Mean score of 1060 with standard deviation of 195 (max score of 1600). This means that [tex]\mu = 1060, \sigma = 295[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1270 - 1060}{295}[/tex]
[tex]Z = 0.71[/tex]
Reed:
Took the ACT, score of 27, so [tex]X = 27[/tex]
Mean of 20.9 with standard deviation of 5.6, which means that [tex]\mu = 20.9, \sigma = 5.6[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{27 - 20.9}{5.6}[/tex]
[tex]Z = 1.09[/tex]
Due to the higher z-score, Reed performed better in relationship to their peers
In AGHI, GI is extended through point I to point J, mZGHI = (2x - 3)º,
mZIGH = (2x + 15)°, and m_HIJ = (7x – 18)'. Find mZGHI.
Answer:
m<GHI = 17°
Step-by-step explanation:
m<GHI = (2x - 3)°
m<IGH = (2x + 15)°
m<HIJ = (7x - 18)°
<HIJ is an exterior angle of ∆GHI
<GHI and <HIJ are both interior angles of ∆GHI that are opposite to the exterior angle.
Therefore, based on the exterior angle theorem of a triangle, we would have the following equation:
m<GHI + m<IGH = m<HIJ
(2x - 3)° + (2x + 15)° = (7x - 18)° (substitution)
Solve for x
2x - 3 + 2x + 15 = 7x - 18
Add like terms
4x + 12 = 7x - 18
4x - 7x = -12 - 18
-3x = -30
Divide both sides by -3
x = 10
✔️m<GHI = (2x - 3)°
Plug in the value of x
m<GHI = 2(10) - 3 = 20 - 3
m<GHI = 17°

y = -½x - 8
Step-by-step explanation:
You can see that (0,-8) and (2,-9) are points on the line. Use their coordinates to find the slope of the line.
Then use the slope and one of the points to write an equation in point-slope form.
The tables show the amount earned by James and Paco working at the same store.
James's Hours Amount Earned
3 $35.40
5 $59.00
8 $94.40
Paco's Hours Amount Earned
2 $24.00
4 $48.00
7 $84.00
What are the two equations that can represent James and Paco's hourly wages, where h is the number of hours worked and d is the amount of money earned?
Compare the equations to determine if there is any difference between what James and Paco make each hour.
its pacos hour because as you can see he makes more i just know trust me its pacos

Answer:
Step-by-step explanation:
x - 2y =8
-2y = -x + 8
[tex]y = \frac{-1}{-2}x+ \frac{8}{-2}\\\\y =\frac{1}{2}x - 4[/tex]
When x = 4,
[tex]y = \frac{1}{2}*4-4\\\\ = 2-4\\\\y = -2[/tex]
(4, - 2)
When x = -4,
[tex]y =\frac{1}{2}*(-4) - 4\\\\ = -2 - 4\\\\= - 6[/tex]
(-4, -6)
Plot the points (4, -2) and (-4 , -6) in the graph and Join the points
