Ryan runs 3 miles in 28 minutes. at the same rate, how many miles would he run in 42 minutes?

1 answer:

5 0

If 3mile=28 min
x mile=42 min
cross multiply
x=3/28
therefore if 3/28=1 min
then x mile= 42 min
cross multiply
42 x 3/28 =21 x 3/14
=3 x 3/1
=9
The answer is 9 miles

Solve the following equation for x: 5x + 3y = 15.

zepelin [54]

Answer:

B) x = (-3/5)y + 3

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

first, subtract 3y from btoh sides:

5x + 3y (-3y) = 15 (-3y)

5x = -3y + 15

Next, divide 5 from both sides:

(5x)/5 = (-3y +15)/5

x = (-3/5)y + 3

B) x = (-3/5)y + 3 is your answer.

2x-10+x-6=2<br> combing like terms..

maria [59]

First you will combine the “x’s” so x+2x=3x then you would add 10 and 6 16 and subtract it to move it to the other side of the = so 2-16= -14 then you would divide 3x and -14 by 3 then there is your answer hope this helps
