Whitepunk [10]

Answer:

<em><u>The</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u>,</u></em><em><u> </u></em><em><u>q</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>16</u></em><em><u>.</u></em>

Step-by-step explanation:

1) Divide both sides by 3.

q - 7 =  \frac{27}{3}

2) Simplify 27/3 to 9.

q - 7 = 9

3) Add 7 to both sides.

q = 9 + 7

4) Simplify 9 + 7 to 16.

q = 16

What do you do to both sides to<br> r? What is r? 3/8 r = 6 HELP ME
faust18 [17]

Answer:

r = 16

Step-by-step explanation:

\frac{3}{8}r = 6 \\\\

Multiply both sides by 8

8*\frac{3}{8}r = 6*8\\\\3r = 48\\

Divide both side by 3

\frac{3}{3}r=\frac{48}{3}\\\\r = 16

OR

Multiply both side by (8/3)

\frac{8}{3}*\frac{3}{8}r=6*\frac{8}{3}\\\\r = 2*8\\\\r = 16

write an equation to represent the information in this problem. Jerel runs five days each week. on each of 4 days, he runs 2.3 km. if jerel runs a total of 14km, how many kilometers does he run on the fifth day?

Let x be the distance run on the fifth day

Total distance run on all the four days = 2.3 * 4 = 9.2 km

Required equation : x + 9.2 = 14

x = 14 - 9.2

x = 4.8 km
