Answer:

a. Equation: 0.8x+30 = 1.2x+14

b. Solution: 40 Stickers

Step-by-step explanation:

"per sticker" means there will be a variable which will be how many stickers he buys next to the price and the fee is the amount of money that will be added onto the fee price.

Company A equation: 0.8x+30

Company B equation: 1.2x+14

You will set these equal to each other to find the number of stickers which cost the same for both companies, then solve for x by doing inverse operations.

0.8x+30 = 1.2x+14 [subtract 14 from both sides]

0.8x+16 = 1.2x [subtract 0.8x from both sides]

16 = 0.4x [divide 0.4 from both sides]

x = 40 [The solution is 40 stickers]

You are correct for the first part, you would be 16 and your Mom would be 44. After 8 years, you would be 24 and your mother would be 52. You solve the second part by adding 8 to 16 which equals 24. Then multiply 24 times 3 which equals 72. Lastly, subtract 20 from 72 to find your mother's new age. Which would be 52.

Hope this helps !

The sum of two consecutive odd numbers is 52. what are the two odd numbers

schepotkina [342]

Let assume two consecutive odd numbers 2x+1 and 2x+3
It is given their sum is 52.
So we can write equation as
$2x+1 + 2x+3 = 52$
$4x+4 = 52$

On subtraction 4 on both sides of equation

$4x+4 - 4 = 52-4$
$4x = 48$
$\frac{4x}{4} = \frac{48}{4}$
x = 12
So the numbers are
first number is = $2*12 + 1 = 25$
Second number is = $2*12 + 3 = 27$

So the required numbers are 25 and 27.
