Answer:

x= -3

y= -6

Step-by-step explanation:

8x - 3y= -6 .........equation 1

-8y + 7y= -18..........equation 2

Using elumination method

Multiply equation 1 by -8 and multiply equation 2 by 8

-64x + 24y = 48

-

64x + 56y =-144

-32y = 192

y = 192/-32

y= -6

Substitute -6 for y in equation 1

8x - 3(-6) = -6

8x + 18= -6

8x= -6 -18

8x=-24

x= -24/8

x= -3

Hence x = -3 and y = -6

Answer:15/20 3/4

Step-by-step explanation:

Because 3 times 5 =15 and 4 times 5= 20 so that will be 15/20

Then if you multiply 3 and 4 by 1 it will give you 3/4

Answer:

15/20 3/4

Step-by-step explanation:

Step-by-step explanation:

To find coordinates, we need the equation of the line segment with restrictions. I think you meant to say “line segment” as lines go infinitely in 2 directions and could not be broken up into ratios. Let’s say your segment is 24 feet long. You could then label AB as 5x and BC as x since that is a ratio of 5:1 …………We’d then have an equation

5x + x = 24 … or 6x = 24…..or x = 4 which would make AB = 20 and BC = 4…but this would not give us coordinates of points.

Answer:

1. Ron paid 4 dollars on sales tax and 2. The total Ron paid was 28.99

Step-by-step explanation:

Answer:

Answer to Part A: To solve this we must first find out how much of a discount is there. First we must divide 49.99 by 2 which equals about 24.99. After that we minis the discount with the original price, which equals 25.00. Then we divide 25.00 by 8 which equals 3.12. So then the sales tax must be 3.12 dollars.

Answer to Part B- First do all the math from Part A, then just add 3.12 to the price of 25.00. Which equals 28.12 so the answer must be 28.12 Dollars.

Answer:

F = 9/5C + 32

Step-by-step explanation:

F = 9/5C + 32

Since F means Fahrenheit and C means Celsius

Therefore the answer is already written

Answer: F = 9/5C + 32

Answer: C = 5/9 ( F - 32 )

Answer:

4 days

Step-by-step explanation:

to find this our you must add 78 and 25 before doing anything as they are both part of the daily pass rates

78 + 25 = 103

now you must divide 350 by 103

350/103 = 3.39805825

because you want to find when the season pass is less expensive than the daily pass you must round up

4 is your answer

Answer:

5.4miles

Step-by-step explanation:

Step one:

given

Casey traveled 4 3/5 miles

She traveled another 1/2 mile

Then,  an additional 1/4 mile

Required:

the total distance travelled

Step two;

the total distance is the summation of the individual distances covered

=4 3/5  + 1/2 + 1/4

= 23/5+1/2+1/4

lcm = 20

92+11+6/20

=109/20

=5.4miles

Answer:

-6 < n < -4

Step-by-step explanation:

Solving the inequality 5 + 7n > -37  :

5 + 7n > -37

⇔ 7n > -37 - 5

⇔ 7n > -42

⇔ n > -42/7

⇔ n > -6

Solving the inequality n + 8 < 4 :

n + 8 < 4

⇔ n < 4 - 8

⇔ n < -4

Then , the solution to the compound inequality

5 + 7n > -37 and n + 8 < 4 is :

All real numbers n ,where -6 < n < -4

The solution in interval notation (-6 , -4)

Answer: $462.5

Step-by-step explanation:

1.) You are going to multiply 24.50 and 5

(24.50×5= 122.5)

2.) Then subtract your answer with the money that's in the account:

(450-122.5= 327.5)

3.) Now he added money to his account so you add but first you figure out the amount

(45×3= 135)

Now you can add the amount to the remaining balance

(327.5+135= 462.5)

The answer will be 2.

If you add 2+2+2 it will equal 6 + the 2 on the scale will be 8 that makes it equal to the other scale
