so y = 5x becomes y = 5 x -5
y= -25

x=-5 and y=-25
Answer 2
Answer: 5x=2x-15 =  x=-5

A coin-operated machine sells plastic rings. It contains 6 yellow rings, 11 blue rings, 15 green rings, and 3 black rings. Suzy puts a coin into the machine. Find the theoretical probability that she will get a green ring. Express your answer as a fraction in simplest form.

Answers

1) you have to add all the rings together to find the denominator

6 + 11 + 15 + +3 = 35

2) the numerator is the amount of rings of the certain color you are trying to find the probability of

15

3) find the theoretical probability! 15/35

4) simplify

15/35 (divide both by 5) = 3/7

  • opposite vertical angle is the two opposite angles on a parallel line at the point of intersection.

         angle y=74°   (opposite vertical angle).

  • The angle on a straight line is 180°

        angle y+z=180°

A pound of seedless red grapes costs $2.75. Drew must spend less than $9.35 on a bunch of seedless red grapes.Inequality:

Solution:

Interpretation:

Answers

$2.75x > $9.35

$9.35/$2.75=3.4 lbs.

Drew can buy 3 lbs of seedless grapes for less than $9.35.

Inequality:          x = the number of pounds of grapes

2.75x < 9.35     [2.75x is less than 9.35, since Drew must spend less than $9.35]

Solution:

To find the solution, you need to isolate/get "x" by itself in the inequality.

2.75x < 9.35   Divide 2.75 on both sides to get "x" by itself

(2.75x)/(2.75) <(9.35)/(2.75)

x < 3.4  

Interpretation:

x is less than 3.4, so Drew has to buy less than 3.4 pounds of grapes in order to spend less than $9.35 [which is the most/maximum $ he has]

chris rented a truck for one day. there was a base fee of $16.95, and there was an additional charge of 87 cents for reach mile driven . chris had to pay $229.23 when he returned the truck . for how many miles did he drive the truck

Answers

if he rented the truck for only 1 day, you would have to take away the $16.95 away from the $229.23 which would equal $212.28 then further you would divide $212.28 by 87 cents
but first you'd have to turn 87 into dollars which would be $0.87


$212.28÷$0.87=224

hopefully this is correct and helps ♡♡~chyna
