Focus on the angles at the bottom right
Those two angles add to 180 since they form a straight line. We consider them supplementary angles.
x+(4x-20) = 180
5x-20 = 180
5x = 180+20
5x = 200
x = 200/5
x = 40

Answer:
x = -6 (correct answer)
mistakes were made in Step 2 and Step 5.
Step-by-step explanation:
The mistake is made in Step 2, application of the distributive property. This is often a source of error. Here, the error is in signs.
Step 1: 12 = -2(x -4) -8
Step 2: 12 = -2x +8 -8 . . . . . . the correct step 2
Step 3: 12 = -2x . . . . . . . . . . . like terms combined
Step 4: -6 = x . . . . . . . . . . . . . divide by -2
__
Check
12 = -2(-6 -4) -8 = -2(-10) -8 = 20 -8 = 12 . . . . answer checks OK
__
Comment on other mistake
In the original Step 5, -2 was divided on the right and added on the left. This is a violation of the properties of equality, so guarantees a wrong answer. The same operation must be performed on both sides of the equation.
An additional mistake was made in that the answer was not checked.

Chris has 7/8 yards of purple ribbon and one whole one over 6 yards of ribbon Chris has a total of three holes to over 3 yards of ribbon how many yards of Chris's ribbon are neither purple nor green
Answers
Complete question :
Chris has 7/8 yards of purple ribbon and 1 1/6 yards of green ribbon. Chris has a total of 3 2/3 yards of ribbon. How many yards of Chris's ribbon are neither purple nor green.
Answer:
1.625 yards
Step-by-step explanation:
Purple ribbon = 7/8 yards
Green ribbon = 1 1/6 yards = 7/6 yards
Total ribbon = 3 2/3 yards = 11/3 yards
Ribbon that is neither purple nor green :
Total ribbon - (green + purple ribbon)
7/8 - (7/6 + 7/8)
11/3 - (28 + 21) / 24
11/3 - 49/24
= 1.625 yards

HELP!!!! BRAINLIEST!! Jason says that if you multiply each length in a Pythagorean triple by the same factor, you will get another Pythagorean triple. Explain why Jason is correct.
(kels and emily... PLZ DONT ANSWER!!)
Answers
Answer:
The Pythagorean theorem used in right-angled (equilateral) triangles is a relationship between the sides of a right-angled triangle, where the sum of the square of the legs is equal to the square of the hypotenuse.
If a and b are legs, and c is the hypotenuse, then
a2 + b2 = c2.
Because the triangle is right angled, there is no greater side length in the triangle, so an unlimited number of Pythagorean positions can be produced by flipping the sides.

Step-by-step explanation:
$37.00 + $42.00 = $79.00 < b (bill)
b + t (sales tax) = c (total cost)
(7%/100 = 0.07)
(0.07 * 79 = 5.53)
(t = $5.53)
$79.00 + $5.53 = $84.53

Complete question :
You randomly choose a tile. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth. The probability of choosing two even numbers is
Tiles : 7,6, 5, 8, 9, 10, 20
Answer:
2 /7
Step-by-step explanation:
The probability of a compound event in the scenario described above :
P(1st pick) * p(second pick)
Recall: this event is without replacement
P(choosing two even numbers)
Probability = required outcome / Total possible outcomes
Required outcome = even Number tiles = (6, 8, 10, 20) = 4
Total possible outcomes = number of tiles = 7
P(even number on first pick) = 4/7
P(even on second pick) = 3 / 6 = 1/2
P(compound event) = 4/7 * 1 /2 = 4 /14 = 2 /7
