It seems that you are trying to solve for X. The first steps would be to use inverse operations in order to isolate and then solve for X. You would have to distribute the 4 into x+8, giving you 4x+32-4 = 34-2x. Then simplify it a bit, giving you 4x+28=34-2x. Add 2x to both sides and subtract 28 from both sides. This gives you 6x=6. Divide by 6 on both sides and you get X=1.

Answer: X=1

Not sure exactly what you are supposed to be doing but, I foiled the 4(x+8) and it became 4x+32-4=34-2x. I then did 32-4 which makes it 4x+28=34-2x. Then I added 2x to both sides making 6x+28=34 and then subtracted 28 from both sides making 6x=6 then divided both sides by 6 and got x=1.

What is the area of Vivian’s garage door?

sergey [27]

The area of Vivian’s garage door is 62.5 square feet

<h3>Area of composite shape.</h3>

The Vivian garage is made up of a trapezoid and a rectangle. The area of the door is expressed as;

Area = Area of rectangle + area of trapezoid

Area = (5 * 8) + 0.5(7 + 8)*3
Area= 40 +22.5
Area = 62.5 square feet

Hence the area of Vivian’s garage door is 62.5 square feet

A ship is carrying gold bars and silver bars in the ratio 13:17. The ship's load

andreyandreev [35.5K]

Using proportions, considering the weight of each bar and the ratio, it is found that the ship is carrying 52 gold bars.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Each bar weighs 5 kg, and the total weight is of 600 kg, hence the number of bars is given by:

n = 600/5 = 120.

The proportion of gold bars is given by:

p = 13/(13 + 17) = 13/30

Hence, out of 120 bars, the number of gold bars is given by:

nG = 120 x 13/30 = 4 x 13 = 52.

Trash Cans: Elliot's family has a cylinder shaped trash can. It takes the family a few days to fill the trash can up. Elliot wan

Elza [17]

The volume of cylinder shaped trash can is 4698 cubic inches, if the trash can has a height of 24.90 inches and a diameter of 15.50 inches.

Step-by-step explanation:

The given is,

Trash can has a height of 24.90 inches

Diameter of 15.50 inches

Step:1

Formula to calculate the volume of cylinder,

$Volume, V = \pi r^{2} h$ .............................(1)

Where, r - radius of cylinder

h - Height of cylinder

From given,

h - 24.90 inches

D - 15.50 inches

Diameter to radius conversion,

$Radius, r = \frac{d}{2}$

$= \frac{15.50}{2}$

r = 7.75 inches

Equation (1) becomes,

$V = \pi (7.75^{2} )(24.90)$

$= \pi (60.0625)(24.90)$

$=\pi (1495.556)$

$=(3.1416) (1495.556)$ (∵ $\pi = 3.1416$ )

= 4698.42

≅ 4698 cubic inches

Volume of trash can, V = 4698 cubic inches

Result:

The volume of cylinder shaped trash can is 4698 cubic inches, if the trash can has a height of 24.90 inches and a diameter of 15.50 inches.

If you are driving 20 meters per second, what would be the equivalent of that in miles per hour?

melomori [17]

$\frac{20 meters}{1 second} \frac{60 seconds}{1 minute} \frac{60 minutes}{1 hour}$

the fractions are set up so that each unit cancels out until its only meters/hour

you can multiply all the numerators together to get 72000 and all the denominators to get 1

72000 meters/1 hour

72000 meters in 1 hour

hope this helped
