Answer:

y = 25 and x = 10

Step-by-step explanation:

the angles on top and on bottom are equal so...

5y - 25 = 100

5y - 25 + 25 = 100 + 25

5y = 125

5y/5 = 125/5

y = 25

Every line is 180 degrees so we know that if the top and bottom angles are 100 then the other angles need to equal 80

11x - 30 = 80

11x - 30 + 30 = 80 + 30

11x = 110

11x/11 = 110/11

x = 10

Answer: x=10 and y=25

Step-by-step explanation:

ok, so since we know straight angles=180 degrees, so since one part=100, the other smaller angle=80. This means that 11x-30=80 and 5y-25=100. 11*10=110, and 110-30=80, so x=10. 5*25=125, and 125-25=100, so y=25. And lol. me too. When I used to do these problems, I was stuck for a very, very long time. Just try to use logic most of the time.

Sharkira went bowling with her friends.She paid $3 to rent shoes and then 4.75 for each game of bowling. If she spent a total of

9966 [12]

$21 - $3 = $18

$18 - $4.75 = $13.25

$13.25 - $4.75 = $8.50

$8.50 - $4.75 = $3.75

Which means that she played 3 games, and has $3.75 left over.

But if you were to divide 4.75 from 21 it would equal 4 games and $2 left over.

21 - 4.75 = 16. 25

16.25 - 4.75 = 11.50

11.50 - 4.75 = 6.75

6.75 - 4.75 = 2

4 games and $2 dollars left over.

A = {a, b, c, d}

Rama09 [41]

Answer:

No, Johnny is not correct

A U B = {a,b,c,d,e,f,g,h}

Step-by-step explanation:

Johnny's answer does not have c and d, elements that are in A and B, so A U B must have all elements that belong to A or B.

The (U) represents the sum of elements between two sets. So If a set has three elements {@,#,$} and another set has 5 elements {%,^,&}, (U) equals the sum of these sets: {@,#,$,%,^,&}.

The same is true for the sets A and B.

A = {a, b, c, d}

B = {c, d, e, f, g, h}

A U B = {a,b,c,d,e,f,g,h}

Note: c, d are repeated, in A and B. It is not necessary to write them twice in the final answer.

Zach painted 92 square feet in the same amount of time that Blaise painted

Alika [10]

Answer:

The answer to your question is 252 in²

Step-by-step explanation:

Data

Zach = 92 ft²

Blaise = 13500 in²

Who painted more and how many more square inches? = ?

Process

1.- Convert the square feet to square inches

1 ft² ----------------- 144 in²

92 ft² ---------------- x

x = (92 x 144)/1

x = 13248 in²

2.- Subtract the lower value to the higher value

Area = 13500 in² - 13248 in²

Area = 252 in²

3.- Conclusion

Blaise painted 252 in² more than Zach.

Alicia took a friend for a birthday dinner. The total bill for dinner was $40.86 (including tax and a tip). If Alicia paid a 20.

solniwko [45]

Answer:

$33.85

Step-by-step explanation:

Let X be the initial bill:

(100 + 20.7)% of X was paid

120.7/100 × X = 40.86

X = 40.86 × 100/120.7

X = 33.85252693
