At that rate, how many miles (d) will the train travel in 9 h ?

A.
d = 99 + 9

B.
d = 99 ÷ 9

C.
d = 9 ÷ 99

D.
d = 99 • 9

Answers

Answer 1

Answer: it is D you will have to Multiply because its say How many mile so thats how i find out

Answer 2

Answer: The equation is D. If the train goes 99 miles per 1 hour thats 99 multiplied by 1. But if you substitue the 9 in for the 1 then its 99 times 9:)

Evaluate -3+y/5 when y = –2.5

Answers

If you would like to evaluate - 3 + y / 5 when y = - 2.5, you can calculatethis using the following steps:

- 3 + y / 5 = -3 + (- 2.5) / 5 = - 3 - 0.5 = - 3.5 = - 7/2

Thecorrect result would be - 3.5.

If you would like to evaluate (- 3 + y) / 5 when y = - 2.5, you can calculate this using the following steps:

(- 3 + y ) / 5 = (- 3 + (- 2.5)) / 5 = - 5.5 / 5 = - 1.1

The correct result would be - 1.1

When we have the value for the variable, all we have to do is apply the number to replace the variable, then solve.

-3+y/5 will turn into :- -3+-2.5 -5.5
------------------ = -------------= -1.1
5 5

Now we need to divide -5.5 by 5. We get -1.1

Our final answer: -1.1

beyonce michelle and kelly shared a carton of soft drink containing 2 dozen cans. Beyonce takes 3/8 Michelle takes 5/12 and kelly takes 5./24/ How many cans does each person receive?

Answers

Beyonce gets 9 cans worth, Michelle drinks 10 cans worth of soft drink and kelly receives 5 cans worth.

Dozen = 12 so 2 dozens = 12x2=24

3/8 = 9/24 because 8x3=24 & 3x3=9
5/12 =10/24 because 12x2=24 & 5x2=10
5/24 is fine because it is already out of 24
