Isolate the variable by putting numbers over the equal sign and multiplying/dividing. I'll do them for you
A. 7+3m=-29
3m=-29-7
3m=-36
M=-12
B. -5x+7=26
-5x=26-7
-5x=19
X=-3.8
C. 31=4-9y
31-4=-9y
27=-9y
-3=y
D. -52-3u=8
-3u=8+52
-3u=60
U=-20
E. 6-x=15
-x=15-6
-1x=9
X=-9
Hope this helps

marin [14]

Answer:

70 minutes

Step-by-step explanation:

Mary can type the number of letters in 20 minutes = 6

Maggie can type the number of letters in 20 minutes = 5

Su Ying can type the number of letters in 20 minutes = 2

Working together they can type the number of letters in 20 minutes

= 6 + 5 + 2

= 13 letters

Working together they can type the number of letters in 1 minute = $\frac{13}{20}$

To type 45 letters time taken by them = $\frac{45}{\frac{13}{20} }$

= $45\times \frac{20}{13}$

= $\frac{900}{13}$

= 69.230 ≈ 70 minutes

It will take them 70 minutes to type 45 letters.
