Michael is 4 times as old as Brandon and is also 27 years older than Brandon. how old is Brandon

Answers

Answer 1

Answer: let's represent Brandon's age by x and Michael is 4 times as old as Brandon so 4x andx+ 27. The equation is
4x=x+27 Therefore Brandon is 9 years old.
4x-x=x-x+27 4x=4*9=36
3x=27 x+27=9+27=36
3x/3=27/3
x=9

Find two consecutive odd integers whose sum is 176

Answers

consecutive odd integers aer 2 apart

they are n and n+2
the sum is add
n+n+2=176
2n+2=176
minus 2 both sides
2n=174
divide both sides by 2
n=87
n+2=89
the numbers are 87 and 89

What's the formula to perimeter

Answers

The formula is:

Perimeter = (the distance all the way around the outside of the figure) .

How to calculate the distance all the way around the outside of the figure
is different for every shape.

A few of them are:

Square . . . . . 4 x the length of one side

Rectangle . . . . . (2) x (length + width)

Circle . . . . . (2 pi) x (radius)

etc.

as a puppy, kim's dog weighs 15 ounces. as an adult, kim's dog weighs 8 pounds. how many ounces did kim's dog gain

Answers

The answer is 113 ounces.

Kim's dog weighs 8 pounds. Since 1 pound is 16 ounces, Kim's dog weighs 8 × 16 ounces = 128 ounces.
As a puppy, Kim's dog weighs 15 ounces.
So, the weigh that Kim's dog gained is subtraction of 128 ounces and 15 ounces:
128 ounces - 15 ounces = 113 ounces.

Therefore, Kim's dog gained 113 ounces.
