Enter the value for x that makes the equation 1/2 (4x+12)+5x=30 true.

1 answer:

8 0

First, distribute the (1/2) into (4x+12) by multiplying them.

The equation becomes:

2x + 6 + 5x = 30

On the left side, combine “like terms” through addition.

7x + 6 = 30

Subtract 6 from both sides:

7x = 24

Finally, get x alone by dividing both sides by 7:

x = 24/7, or if you wanted to round the decimal answer, it’s about 3.429.

Answer:

The playground is 160ft by 360ft.

The model is 4in by 9in

First, 1ft = 12 inches.

Then the measures of the playground, in inches, is:

160*12in = 1920 in

360*12in = 4320in

The playground is 1920in by 4320in.

Then, the ratios between the measures of the playground and the model are:

1920in/4in = 480

4320in/9in = 480

This means that each inch in the model, represents 480 inches in the actual playground.

nikitadnepr [17]

Answer: $A_2=\frac{\pi(2D)^{2}}{4}$

Step-by-step explanation:

1. You have the following formula for calculate the area of the original circular chip:

$A_1=\frac{\pi(D)^{2}}{4}$

Where D is the diameter of the circle.

2. Then, if the diameter of the original circular chip is doubled (2D) to use in a new board game, the area of the new chip can be calculated with the following formula:

$A_2=\frac{\pi(2D)^{2}}{4}$
