1. 1*1/6= 1 /6=1.67

2. 9*7/10= 63/10= 6.3

3. 7*4/8= 28/8= 3.5

4. 1/2 of 2= 1/2*2= 0.5*2= 1

5. 1/12 of 2= 1/12*2= 8.33*2= 16.66

6.2/6 of 2= 2/6*2= 3.33*2= 6.66

7. 1/3 of 5= 1/3*5= 3.33*5= 16.65

Solve the following system of equations for a and for b:

viktelen [127]

Answer:

$a=3\\b=1$

Step-by-step explanation:

$9a+3b=30\\8a+4b=28$

Let's solve the second equation for a to later on replace it in the first equation.

$8a+4b=28\\8a=28-4b\\a=\frac{28-4b}{8}$

Now plug this into the first equation.

$9a+3b=30\\9(\frac{28-4b}{8})+3b=30$

Distribute the 9

$(\frac{252-36b}{8}) +3b=30$

Break down the fraction.

$\frac{252}{8}-\frac{36b}{8}+3b=30$

Simplify.

$\frac{63}{2}-\frac{9}{2}b+3b=30$

Subtract $\frac{63}{2}$

$-\frac{9}{2}b+3b=30-\frac{63}{2}$

Combine like terms.

$\frac{-9+2*3}{2}b=\frac{30*2-63}{2}$

$\frac{-9+6}{2}b=\frac{60-63}{2}$

$\frac{-3}{2}b=\frac{-3}{2}$

Muliply by the reciprocal or inverted fraction next to b.

$(-\frac{2}{3})(-\frac{3}{2}) b=-\frac{3}{2}(-\frac{2}{3})$

$b=1$

Now plug this value into any of the equations to find the value of a.

$8a+4b=28\\8a+4(1)=28\\8a+4=28\\8a=28-4\\8a=24\\a=\frac{24}{8}\\ a=3$

A planter shaped like a rectangular prism has a length of 4 meters, a width of 4 meters, and a height of 3 meters. Attached to t

Blababa [14]

Answer:

Planter 1 is 48 meters cubed

Planter 2 is 24 meters cubed

Total volume = 72

Step-by-step explanation:

The formula for the volume of a rectangular prism is length times width times height. So, 4*4*3. This equals 48. If the other planter is half the volume, divide 48 by 2 to get 24 meters cubed. To find the total area add both results to get a total of 72 meters cubed.
