Answer:
x=7
y=2
Step-by-step explanation:
10 + 2x = -2y ➡y = -5-x
replace y with -5-x in the first equation
-5-x-x = 9➡ -2x-5 = 9 ➡-2x = 9+5 ➡ x = -7
now use this information to find value of y
y - (-7)=9 ➡y = 2
630/105=6 minutes per dish
630/70=9 minutes per dish
15 minutes:2 dishes
630/15=42
It will take them 42 minutes to rinse 630 dishes together.
Actual distance is 75 miles
1 inch = 15 miles
Multiply 5x15
Gives you 75
