Try D), Correct me if I'm wrong
Because the spacing is in inches, the total length of the string is 28 * 12 = 336 inches long
subtract the distance to the first light: 336 - 16 = 320 inches left
the spacing is 4 inches so now you would divide the length by the spacing to get the quantity of lights:
320 / 4 = 80 lights
Answer:
the value of 3b ÷ a is 3 ÷ 70
Step-by-step explanation:
The computation is shown below:
Given that
a × b = 70
So it could be write as
a = 70 ÷ b
And, the value of 3b ÷ a is
= 3b ÷ 70 ÷ b ÷ 1
= 3b ÷ 70b
= 3 ÷ 70
Hence, the value of 3b ÷ a is 3 ÷ 70
