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

1. 42 ÷ 8 x 2 = 5.25 x 2
= 10.5
2. 24 - 10.5 + 4 = 17.5
I believe #7 would be 5:13, #8 to be 6:7, #9 to be 13:18, #10 to be 18:5.
I hope this helps.
