Answer:

Solution 1

Step-by-step explanation:

Alternate interior angles are congruent (not supplementary), so the equation used in Solution 1 is the correct one.

Solution 2 incorrectly assumes that the given angles are supplementary. They would be if they were "same-side" interior angles, but they are not.

Answer:

Solution 2 is incorrect

Step-by-step explanation:

Alternate interior angles should equal each other if the lines are parallel

What is the value of X in this proportion? (image of the proportion included)

Answers

X = 5
4x/50 = 2/x take 4x and multiply it by the denominator in the other fraction it = 4x^2 do the same for the 2 &50 you get 100 now you have 4x^2=100 take the 4 divide it on both sides so 4/4=0 and 4/100=25 now you have
x^2=25 find the square root of 25= (5) so X=5

u have to cross multiply. (multiply 4x by x and 50 by 2)

Yolanda spends 8/23 hours per month playing soccer. Approximately how many hours does she play soccer in a year

Answers

Given:
8 2/3 hours per month
12 months in a year.

Number of hours she play soccer in a year.

8 2/3 must be converted to improper fraction.

((8*3)+2)/3 = 26/3

26/3 * 12 = (26 * 12)/3 = 312/3 = 104

Yolanda spends 104 hours in a year playing soccer.

(8+2/3)*12=96+2*12/3=96+2*4=96+8=104
Approximatively 104h per year

When their report cards came back, Pete, Chris, and Dina realized that the number of A's they each received was in the ratio 4:2:5. If Pete got 14 more A's than Chris, how many A's did Dina get?

Answers

Answer:

The number of A's Dina got = 5/11 × 77 = 385/11 = 35

Step-by-step explanation:

The number of A's Pete , Chris and Dina received are in the ratio of 4:2:5.

Let the total number of A's = y

Total from ratio = 4 + 2 + 5 = 11

chris A's = 2/11 × y

pete's A's = 2/11 × y + 14 = 4/11 × y

pete's A's

2/11 y + 14 = 4/11 y

14 = 4/11 (y) - 2/11 (y)

14 = 2/11 (y)

cross multiply

2y = 14 × 11

divide both sides by 2

y = 154/2

y = 77

Total number of A's = 77

The number of A's Dina got = 5/11 × 77 = 385/11 = 35
