Set up a proportion.

\frac{3~minutes}{2~questions} = \frac{x~minutes}{12~questions}

Cross multiply.

2x=36
x=12

It would take her 12 minutes.

-----------------------------------------

Formula for surface area of a cube: 6a² where a=20.

6 x (20)²
6 x 400
= 2400

Surface area: 2400 cm

----------------------------------------------

Mean absolute deviation: The average distance from each number in the set to the mean of the set.

Mean of the set: \frac{(3+8+10+12+15)}{5} =  \frac{48}{5} = 9.6

9.6-3=6.6
9.6-8=1.6
10-9.6=0.4
12-9.6=11.4
15-9.6=5.4

Mean of 6.6, 1.6, 0.4, 11.4, and 5.4: \frac{(6.6+1.6+0.4+11.4+5.4)}{5} =  \frac{25.4}{5} = 5.08

3x+30+x=10+2x+5x+2 <br> i need help fast
kupik [55]

Answer:

x=6

Step-by-step explanation:

Group Like Terms:

3x+x+30=10+2x+5x+2

Add similar elements 3x+x=4x:

4x+30=10+2x+5x+2

Add similar elements 2x+5x=7x:

4x+30=10+7x+2

Group like terms:

4x+30=7x+10+2

Add the numbers 10+2=12:

4x+30=7x+12

Subtract 30 from both sides:

4x+30-30=7x+12-30

Simplify:

4x=7x-18

Subtract 7x from both sides:

4x-7x=7x-18-7x

Simplify:

-3x=-18

Divide both sides by -3:

\frac{-3x}{-3} =\frac{-18}{-3}

Simplify:

x=6

Hence, the correct answer is 6
