The difference of two numbers is 4 and their sum is -7. What is their product?
1 answer:
Answer:
The product is 8.25
Step-by-step explanation:
Let
x-----> one number
y ----> the other number
I assume x>y
x-y=4 ----> equation A
x+y=-7 ---> equation B
Solve the system by elimination
Adds equation A and equation B
x-y=4
x+y=-7
-----------
2x=-3
x=-1.5
Find the value of y
x-y=4
-1.5-y=4
y=-1.5-4=-5.5
The numbers are -1.5 and -5.5
Find their product
(-1.5)(-5.5)=8.25

Answer:
Well to find 1/3 of something you have to multiply it by 1/3.
1/3 in decimal form is .33 repeating.
17.55 * .33 = 5.79
17.55 + 5.79 = $23.34
$23.34 is the total profit.
A factor of 24 but not 2 it would be 3
