Whats is 7 = 12v - 24?

Answers

Answer:

To the nearest tenth: v = 2.6

To the nearest hundredth: v = 2.58

Fraction form = 31/12

Step-by-step explanation:

1. Add 24 to both sides to cancel it out on the right

7 = 12v - 24

+24          +24

2. Divide each side by 12

31 = 12v

31/12 = 2.5833333

12/12 = 1v = v

v = 2.583333

It’s V=31/12

(1). 7=12v-24 (12v is a variable so you move it left hand side and change its sign)

(2). 7-12v=-24 (7 is a constant so move it to the right hand side and change its sign)

(3). -12v=-24-7 (now calculate the difference -24-7)

(4). Now it’s -12v=-31, now after that divide both sides of the equation by -12

(5). So the answer is V=31/12

Find the length of the segment indicated. Round your answer to the nearest tenth if necessary

Answers

okay so we know that a circle is 360°

the one angle is 135 degrees and to find the other one we can just subtract 360 - 135

the other angle is 225°



we can set it up as:

12 yd x
——— = ——-
225 135


to find x, cross multiply 135 and 12 which gives you 1,620
1,620 / 225 = 7.2

the other angle is 7.2 yards!

Karl needs to build a stage that has an area of 84 square feet. The length of the stage should be longer than the width. What are the possible whole number measurements for the length and width of the stage?

Complete the table with possible measurements of the stage.

Answers

Answer:

84 = L x w

84 = 84 x 1

84 = 42 x 2

84 = 28 x 3

84 = 21 x 4

84 = 14 x 6

84 = 12 x 7

Each 5 minutes represent 1 mile. This can be also referred as independent and dependent variables. It takes 5 minutes for 1 mile. Or T=5m (m=minutes) D=1

so 5 x 2 (5 minutes x 2) = 10 minutes and 10 minutes equal to 2 miles, each 5 minutes is another mile. For example, 60 minutes (1 hour) 60 divided by 5 = 12 so in 1 hour (60 mins) equal to 12 miles in total! hope this helps at least a bit! :)
