Find the value of x.

Mathematics
1 answer:
Karolina [17]2 years ago
6 0

Answer:

x=21

Step-by-step explanation:

Following the vertical angles, we can assume that the equation that has x and 87 are equal to each other. From then, you set them equal to each other and solve for x.

87=4x+3

84=4x                  subtract 3 from both sides

21=x                     divide by 4 to get the x alone on both sides

Use the following work shown below to answer the following question.​
zysi [14]

Answer:

\frac{3 + \sqrt{3x} }{3 - x}

Step-by-step explanation:

You can use the work they gave you and continue from there:

\frac{\sqrt{3}(\sqrt{3}) + \sqrt{3}(\sqrt{x})  }{(\sqrt{3}) ^{2} - (\sqrt{x} )^{2} }

First, simplify the numerator:

\frac{3 + \sqrt{3x} }{(\sqrt{3}) ^{2} - (\sqrt{x}) ^{2} }

Finally, simplify the denominator:

\frac{3 + \sqrt{3x} }{3 - x}

345 ft/min = ___________ ft/h
Pavlova-9 [17]

the rate given is 345 ft/min

this means within 1 min distance is - 345 ft

we have to convert this speed to ft/h

1 hour is equivalent to 60 minutes

so if 60 minutes equals 1 hour

1 minute is equal to - 1/60 hr

so the distance within 1 minute is - 345 ft

since 1 min = 1/60 hr

distance within 1/60 hour = 345 ft

therefore distance in 1 hour = \frac{345}{1/60} = 345 * 60 = 20 700 ft

answer is 20 700 ft/h
