Answer:
For the first one, the answer is 20.82
Step-by-step explanation:
you first add 2.65 to 2.56 and then add 5.9 to 5.9 and you add them together and you get 16.92 and then you subtract it from 37.74
also for the second one I don't understand. could you be a little more clear?
Step-by-step explanation:To add the three distances first align the decimal points, adding in place holder zeros if necessary. Then add each place value and rename when necessary.
Answer:
56
Step-by-step explanation:
The n th term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₆ = 17 and a₁₃ = 38, then
a₁ + 5d = 17 → (1)
a₁ + 12d = 38 → (2)
Subtract (1) from (2) term by term to eliminate a₁
7d = 21 ( divide both sides by 7 )
d = 3
Substitute d = 3 into (1) and evaluate for a₁
a₁ + 5(3) = 17
a₁ + 15 = 17 ( subtract 15 from both sides )
a₁ = 2
Thus
= 2 + (18 × 3) = 2 + 54 = 56
This would be +2 so I believe it would be B.
Answer: 3.33 miles per hour
Step-by-step explanation:
This is a fraction equal to
2.5 miles ÷ 0.75 hours
We want a unit rate where 1 is in the denominator,
so we divide top and bottom by 0.75
2.5 miles / 0.75 hours ÷ 0.75
÷ 0.75
= 3.33 miles per hour
