The sum of two numbers is 25 and their difference is 13. Find their product.

solve it

Step-by-step explanation:

X+X=25-13

114

Step-by-step explanation:

Let x+y=25

Let x-y=13

Let's isolate one variable

x-y=13 can be re-written as x=13+y

Now that we isolated x we can replace it in the other equation

(x)+y=25

(13+y) +y=25

13 +2y=25

-13           -13

2y=12

12/2=6

We know that y=6

Let's replace y with 6 to find x

x+(y)=25

x+6=25

-6        -6

x=19

The goal of this problem was to find the product of x and y so now we have to multiply them

19*6=114

Your answer is 114

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
