Answer:

See Below

Step-by-step explanation:

We are given 3 equations.

3x + 8

5x - 20

and

5x + 4y

First lets solve for x using the first two

3x + 8 = 5x -20

Move the variables to one side

3x + 8 = 5x -20

-3x        -3x

8 = 2x -20

+20     +20

28 =2x

28/2 =2x /2

14 = x

Now we have x = 14

Lets plug this into the second equation to solve for the angle

3(14) + 8

42 + 8 = 50

5(14) - 20

70 - 20 =50

Now, lets plug the x and the angle into the third equation to find y

5 (14) +4y = 50

70 + 4y = 50

-70           -70

4y = -20

4y/4 = -20/4

y = -5

So now we have:

x = 14

y = -5

and the angle = 50

Hope this helps!

The ratio of John's money to Jimmy's money is 5:8. Jimmy spent 1/4
erma4kov [3.2K]

Answer:

a. $3600

b. 6:5

Step-by-step explanation:

Put the question into an equation:

8x - 1/4 x 8x = 5x + 450

(simplify before solving) 6x = 5x + 450

(solve) 6x-5x = 450

x = 450

This means that Jimmy had 8 x 450 $ to start with = 3600

you can check this by subtracting a quarter of 3600 from 3600 and also multiplying 450 by 5 and then obtaining their difference. You get 450!

Now ratio of new amounts:

Jimmy now has: $2700

John still has: $2250

so ratio is 2700:2250

simplify to 6:5

Hope this helps

Mrs. Lee's store is running a sale on two different brands of green beans. Earth's Best is 3 cans for $5 and Kroger is 2 cans fo
Snezhnost [94]

Answer: Earth’s Best $1.67 Kroger $2

Step-by-step explanation:

$0.80 multiplied by 3 is $2.40 and $1.33 multiplied by 2 is $2.66.

$1.25 multiplied by 3 is $3.75 and $0.75 multiplied by 2 would be $1.50.

$0.80 multiplied by 3 is $2.40 and $0.75 multiplied by 2 is $1.50.

$1.67 multiplied by 3 is $5.01, but if you round it to the nearest cent, it’s $5 and $2 multiplied by 2 is $4, of course.

Hope this helps!
