Answers

Answer 1

Answer:

Point Form:

(-1/4, -7/8)

Equation Form:

x= -1/4, y= -7/8

Step-by-step explanation:

Answer 2

Answer:

x=-4, y=-6.5

Step-by-step explanation:

First, we need to find the value of x so

x+2=-2

-2 -2

x=-4

now plug the value of x, in the second equation

-3(-4)+2y=-1

12+2y=-1

minus 12 from both sides

12+2y=-1

-12 -12

2y=-13

divide by 2 to get the value of y

y=-6.5

Melanie can run around the track 9 times in 28 minutes. At this rate, how many laps can she run in 1 hour and 15 minutes?

Answers

Step-by-step explanation:

First step is to identify what the problem is asking for and what is given.

9 laps in 28 minutes

Searching for number of laps in 1 hour and 15 min.

1 hour + 15 min. = 75 minutes convert to minutes

9 laps / 28 minutes = x laps / 75 minutes create an equation

9/28 = x/75

9*75 = 28x cross multiply

675 = 28x

x = 675/28 = 24.12 simplify

Melanie can run 24 complete laps in 1 hour and 15 minutes.

C. There are 5 more girls than boys in the class.

D. There is 1 boy out of the 6 students in the class.

Thanks and have a great day! <)

Answers

Answer:

B. There is 1 boy for every 6 girls in the class.

Step-by-step explanation:

Since the ratio is 1 boy per 6 girls and we don't know how many students there are then B is the best answer

hope this helped :))

Answer:

B. There is one boy for every 6 girls in class.

Step-by-step explanation:

When you have a ratio, it compares two numbers. When you have a ratio 1:6 the colon  there can be read as "is to" or "for every".  

That means that ratio can be read as 1 is to 6 or "there is 1 for every 6."

In this case 1:6 represents the number of boys to the number of girls to class. This means that there is 1 boy for every 6 girls in class.

Hope

The variable in the equation 26 = 1 – 3r is r. Remembering the form ax + b = c, what are the values of the constants, a, b, and c in the equation?

Answers

The value of the constant a, b and c in the equation are -3, 1 and 26 respectively.

What is variable?

Variable are numbers represented by letters in a mathematical equation. Therefore,

26 = 1 - 3r

Using the form ax + b = c, where a, b and c are constant.  

The value of a, b and c in the expression 26 = 1 - 3r can be solve as follows:

-3r + 1 = 26

Therefore,

a = -3b = 1c = 26
