Answer: He received a discount of $11.40.

Step-by-step explanation:

To answer this problem we can look at the discount he was given, in this case, it would be 30%.

We can then turn that 30% into a decimal by dividing it by 100.

30/100

This gives us 0.3

After knowing this, we simply multiply 0.3 by the original price of $38.00 and it gives us a discount of $11.40.

What is the value of x in the equation 8 + x = 3?<br><br> −5<br> 5<br> 11<br> 24
Dvinal [7]

Answer: 8 + x = 3

To solve for this, we need to get x by itself on one side of the equation.

Currently, we have 8 being added to x, so we need to perform the opposite order of equations to get rid of 8.

The opposite of +8 is -8, so subtract 8.

Remember, if you add, subract, multiply or divide by any new number, you must do it to both sides of the equation.

8 + x = 3

Subtract 8 from both sides.

8 - 8 = 0

3 - 8 = -5

We're now left with:

x = -5

Your answer is A.) -5.

tester [92]

Answer:

multiply the first equation by -2, then add them

Step-by-step explanation:

7x+4y=-4         *-2 7x+4y=-4 *-2 = -14x-8y=8

5x+8y=28

-14x-8y=8                       x=-4, y=6

-9x=36

x=-4

7(-4)+4y=-4

-28+4y=-4

4y=24

y=6

What is the equation of <br> 3(5x+2)=8x+20
Ivan

Answer:

x=2

Step-by-step explanation:

3(5x+2)=8x+20

Distribute the 3

15x +6 = 8x+20

Subtract 8x from each side

15x-8x +6 = 8x-8x+20

7x+6 = 20

Subtract 6 from each side

7x+6-6=20-6

7x=14

Divide each side by 7

7x/7 = 14/7

x=2
