Select a value: addition property of equality

Mathematics
1 answer:
Whitepunk [10]3 years ago
3 0

Answer:

Addition prop of equality,    multiplication prop of equality,     multiplication prop. of equality

Step-by-step explanation:

For the first one, we know that in order to solve the equation, we need to add 3 to both sides of the equation. When you add a value to both sides of the equation, you're using the addition property of equality.

For the second one, we know that in order to solve the equation, we need to multiply both side by 1/6 (to cancel the 6 out on the left side). When you multiply something to both sides of the equation, you're using the multiplication property of equality.

For the third one, we know that in order to solve the equation, we must multiply both sides of the equation by 5. Like the second problem, this would be the multiplication property of equality (since you're multiplying both sides of the equation by the same thing).

Alexxx [7]

Hi,

Let  the

Youngest brothers age = x+2

Middle brothers age = x+4

Oldest brothers age = x+6  

So,

Youngest brothers age = x+2 = 28+2 = 30 years of age

Middle brothers age = x+4 = 28+4 = 32 years of age

Oldest brothers age = x+6 = 28+6 = 34 years of age

Have a great day!

Three boxes have a total weight of 640 pounds. Box A weights twice as much as Box B. Box C weight 30 pounds more than Box A. How
Zarrin [17]

Answer:

  A: 244 pounds

  B: 122 pounds

  C: 274 pounds

Step-by-step explanation:

We have A+B+C = 640; A=2B; C=A+30. Substituting the last into the first gives ...

  A + B + (A +30) = 640

  2A +B = 610 . . . . . . . . . . . . subtract 30

Substituting the second into this equation gives ...

  2(2B) +B = 610

  B = 610/5 = 122 . . . . . divide by 5

  A = 2B = 244 . . . . . . . .find A from B

  C = A+30 = 274 . . . . . find C from A

Box A weighs 244 pounds; box B weighs 122 pounds; box C weighs 274 pounds.
