What's w?
Well without W, we just have to trial and error.
R could be 2.
7w - 3r = 15
7w - 3(2) = 15
7w - 6 = 15
7w = 21
/7 /7
w = 3
So if W = 3, R could be 2.
Answer:
2 units
Step-by-step explanation:
because the only whole number factor pair to 10 is 2x5 and luckily, it turned out that 5-3=2, so there are no decimals or fractions. Yay!
No it depends on the sum of the two numbers
