What is the value of X?

zepelin [54]

The 3 inside angles of a triangle need to equal 180 degrees.

The angle below the 100 degrees would be 180-100 = 80 degrees.

Now you have 80 and 70, which equals 150 degrees.

Angle X = 180 -150 = 30 degrees

Gabriella drives her car 320 miles and averages a certain speed. If the average speed has been 6 miles less she could have trave

arsen [322]

Answer:

Her average speed is 48 miles per hour.

Step-by-step explanation:

We solve this question using a system of equations.

The speed equation is:

$s = \frac{d}{t}$

In which s is the speed, d is the distance, and t is the time.

Gabriella drives her car 320 miles and averages a certain speed.

So $d = 320$

Then

$s = \frac{320}{t}$

If the average speed has been 6 miles less she could have traveled only 280 miles in the same length of time.

So, which s - 6, d = 280.

$s - 6 = \frac{280}{t}$

From the first equation:

$s = \frac{320}{t}$

$st = 320$

$t = \frac{320}{s}$

Replacing:

$s - 6 = \frac{280}{t}$

$s - 6 = \frac{280}{\frac{320}{s}}$

$320(s - 6) = 280s$

$320s - 1920 = 280s$

$40s = 1920$

$s = \frac{1920}{40}$

$s = 48$

Her average speed is 48 miles per hour.

A student worked 46 hr during a week one summer the student earned $4.90 per hour for the first 40 hr and $7.35 per hour for ove

marysya [2.9K]

First you multiply how much they make per hour by the number of hours they worked that weren’t overtime. So you would multiply 4.9 and 40.
4.9(40)=$196
Then you multiply 7.35 and the number of hours worked overtime. To find the number of hours worked overtime you would subtract 40 from 46.
46-40=6
Now you multiply again.
7.35(6)=$44.10
Then you add the two amounts made together.
196+44.10=$240.10
The student makes $240.10.
