2 answers:
Answer:
r = 29.82
Step-by-step explanation:
We have the equation r/7.1 = 4.2 and are asked to solve for r.
To solve, we need to isolate r, do as followed and multiply 7.1 from both sides:
r/7.1 = 4.2
r = 29.82
Answer:
r = 29.82
Step-by-step explanation:
The opposite of division is multiplication, you will need to multiply 7.1 to both sides.
That would leave:
r = 4.2 (7.1)
r = 29.82
If there are further instructions for rounding, you can round.
Have a nice day!

Black tiles = x
Purple tiles = x+50
Yellow tiles = 5x
-
Total = x + x+50 + 5x = 400
⇒ 7x + 50 = 400
⇒ 7x = 400-50 = 350
⇒ x = 350/7
⇒ x = 50
Black tiles = 50
Purple tiles = 50+50 = 100
Yellow tiles = 5 x 50 = 250
