Answer 1

Answer:

Point Form:  ( 4 , − 5 )

Equation Form:  x  =  4 ,  y  =  - 5

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point Form:  ( 4 , − 5 )

Equation Form:  x  =  4 ,  y  =  - 5

Answer 2

Answer:

(4, - 5)

Step-by-step explanation:

3x - 4y = 32 ........ (1)

5x + 2y = 10 ....... (2)

(2) × 2 + (1)

13x = 52 ⇒ x = 4

3(4) - 4y = 32 ⇒ y = - 5

(4, - 5)

First you need to get the same denominator on both fractions. You can do this buy multiplying the fraction by the other fractions denominator:

1/2 + 1/3

1/2 x 3 = 3/6

1/3 x 2 = 2/6

So the new expression with the same denominators is:

3/6 + 2/6

Then just add the numerators:

If Helena starts school at 8:00am and must spend 45 minutes in each of her 6 classes, with two 30 minute breaks, at what time will she be finished her classes?

Answers

Answer:

1:30 pm

Step-by-step explanation:

45 x 6 (6 classes and 45 min per class) = 270

30 x 2 (2 breaks and 30 min per break) = 60

270 + 60 (Add time together) = 330

330 / 60 (Only 60 minutes in an hour) = 5 1/2

8 + 5 1/2 (Add starting time and at school time together) = 13 1/2

13 1/2 = 1:30 pm (Calculate to actual time)

Clare knows that Priya has a bunch of nickels and dimes in her pocket and 2 points

that the total amount is $1.25. Write an equation that describes the

relationship between the number of dimes and the number of nickels in

Priya's pocket. Let x represent the number of nickels and y represent the

number of dimes.

Answers

Answer:

5x + 10y = 125

Step-by-step explanation:

Let :

Number of nickel = x

Number of dime = y

Nickel = 5 cent

Dime = 10 cent

Total value = $1.25

Total value should be converted to cent since both dime and nickel are both in cent

= $1.25 * 100 = 125 cents

Therefore,

5x + 10y = 125 cents

t
,
t, representing the number of chocolates remaining in the box
t
t days after Chase's birthday.

Answers

The number of chocolates remaining in the box after Chase birthday can be represented by the equation 18 - 4t = 6

Number if chocolates in the box = 18

Number of nights = 4

Remaining chocolates in the box = 6

Based on the information given, the number of chocolates remaining in the box after Chase birthday can be represented by the equation 18 - 4t = 6.

To get the number of chocolates that he takes each night will be:

18 - 4t = 6

Collect like terms

4t = 18 - 6

4t = 12

t = 12/4

t = 3

He takes 3 chocolates every night.

Olivia reads 2/5 of her book on Monday and on Tuesday she reads 1/6 of what is remaining and then on Wednesday she reads the final 35 pages. So how many pages are in the book

Answers

Answer:

Step-by-step explanation:

Here's what we know:

1/6 + 2/5 + x = 1 (the fractions read plus the 60 pages (currently an unknown fraction) makes one whole book)

First we need a common denominator. LCD is 30:

5/30 + 12/30 + x = 1

18/30 + x = 1

Subtract:

x = 30/30 - 18/30

x = 12/30

Now we have an equivalency. 60 pages out of the whole book is equal to 12/30. Or:

60/y = 12/30

Cross multiply:

60 * 30 = 12y

Divide both sides by 12:

60 * 30 / 12 = y

Factor out a 6:

10 * 30 / 2 = y

Factor out 2:

10 * 15 = y

150 = y

There are 150 pages in the book.

Answers

y² = 8y - 15 (alternate angles are equal)

y² - 8y + 15 = 0

(y - 5)(y - 3) = 0

y = 5 or 3

x + 8y - 15 = 180 (angles in a straight line add up to 180)

when y = 5

x + 40 - 15 = 180

x = 155°

when y = 3

x + 24 - 15 = 180

x = 171°

Answers

Answer:

Step-by-step explanation:

3 counselors for every 20 girls

Answer:

15 counselors

Step-by-step explanation:

The ratio of counselors to girls is 6:40. Set this as a proportion:

[tex]\frac{6}{40}[/tex]=[tex]\frac{x}{100}[/tex]

Cross multiply to solve: 6×100=40x

600=40x

x=15

To satisfy the ratio, there needs to be 15 counselors for 100 girls.
