Answer:

We can say that

3x + x + 8 = 32

So:

3x + x + 8 = 32

4x = 32 - 8

4x = 24

x = 24/4

x = 6

How do you find the angle for n? If you can, please show work on how to get to the answer. Thank you!

PtichkaEL [24]

A triangle needs to add up to 180 degrees so 44 plus 37 is 81 so that last angle is 99 degrees then you do 180 minus that angle because those 2 angles need to equal up so not equals 81

A school had a girl:boy ratio 5.4.

Ilya [14]

Answer:

164

The 982 part seems wrong. Are you sure it isn't 981?

around 436 if I use 981 instead. 982 would give a decimal and that would be kinda weird for a part human.

Step-by-step explanation:

You can divide the 205 by 5 to simplify the ratio down. 205/5 = 41. Then you can multiply by 4 to find then number of boys.

981

So you can add the 5 and 4 together to 9 and then divide 981 by 9 to get 109. Then you can multiply by 4 to get 436.

Hope this helps!

d )

$3x + 2 = 14$

$x = 4$

One solution.

_________________________________

e )

${x}^{2} - 1 = 24$

${x}^{2} = 25$

$x =± \: 5$

Two solutions.

A circular racetrack has a diameter of 1/2 mile. How far does a car travel in one lap around the track? Round to the nearest ten

dlinn [17]

Given:
Circular racetrack with a diameter of 1/2 mile

Find: how far does a car travel in one lap around the track?

We need to find the circumference of the racetrack.

Circumference is multiplying pi to the diameter of the racetrack.

Circumference = 3.14 * 1/2 mile
Circumference = 3.14/2 mile
Circumference = 1.57 miles rounded to the nearest tenth is 1.60 miles.
