Answer:
First number=22
Second number=28
Step-by-step explanation:
Since you don't know either of the numbers we can call the first number x. The second number is the first number plus 6 or x+6. The sum is 22 more than the larger number so x+6+22 or x+28. Using this we can create the equation x+x+6=x+28. In order to isolate x we would subract x from both sides ending up with x+6=28. Then subract 6 from both sides to get x=22. This means the first number equals 22. Then to solve for the second number you plug 22 in for x to get the equation 22+6= the second number, so the second number is equal to 28. Look below for just the equation.
x+x+6=x+6+22
2x+6=x+28
-x -x
x+6=28
-6. -6
x=22
22+6
=28
22+28= 28+22
50=50
Answer:
The first puppy would weigh 8.6 ounces, the second puppy would weigh 9.4 ounces, and the third puppy would weigh 8.5 ounces.
We will use the ratio and proportion method ( an equation formed with two ratios that are equal) to solve the question “if <span>it takes 18 gallons of gas to go 400 miles, how many gallons would it take to go 300 miles?” </span>
<span>Let x= the number of gallons for the gas to go 300 miles</span>
18:400=X:300
400x=300*18
400x=5400
X=5400/400
<span>X=13.5 so the answer is B.</span>
