Answer:

12 and 16

Step-by-step explanation:

set up an equation:

since one number is 4 less than the other, let x represent it. for the other number, let x+4 represent it since it's 4 greater than x. set the equation equal to 28 because the sum of the two numbers is 28.

x+x+4=28

now, we solve the equation:

x+x+4=28

2x+4=28

2x=24

x=12.

Since x equals 12, to find the other number, which would be 4 greater than x, we would add:

12+4=16

So, the two numbers are 12 and 16.

How do you solve 1-5+1×(4×4-31)×8

Alja [10]

Hey there!

In order to solve this, remember PEMDAS. First, start with solving whatever is in parentheses. Then, move on to exponents. Then, complete the multiplication and division. Lastly, add or subtract anything remaining. Omit any steps that aren't present.

Parentheses:

<span>1 – 5 + 1 × (4 × 4 – 31) × 8
</span>1 – 5 + 1 × (–15) × 8

Multiplication/Division (Left to Right):

1 – 5 + (–15) × 8
1 – 5 + (–120)
1 – 5 – 120

Addition/Subtraction (Left to Right):

–4 – 120
–124

Your answer is –124.

Hope this helped you out! :-)
