So i did 220 ÷ 8 and got 27.5 then multiplied by 5 to find how many miles and its 137.5
98
2 49
7 7
so the answer is 2 x 7 x 7, which is 2 x 7^2
5136/8 is equal to 642.
You can use a calculator if you'd like.
Answer:
a) 4(t - r) = 4(6 - 2.5) = 4 x 3.5 = 14
b) 4t - r = (4 x 6) - 2.5 = 24 - 2.5 = 21.5
c) 2(3t - 10) = 2(3 x 6 - 10) = 2(18 - 10) = 2 x 8 = 16
d) (t - 2)² = (6 - 2)² = 4² = 4 x 4 = 16
e) cannot decipher the equation
f) 6r + t = 6 x 2.5 + 6 = 15 + 6 = 21
