How kany doulutions does this equation have 25 - 4x=15-3x+10-x
natima [27]
Since it's a one-variable equation, it has only one solution:

25 - 4x = 15 - 3x + 10 - x

25 - 4x + x = 15 - 3x + 10

25 - 3x = 15 - 3x + 10

- 3x = 15 - 3x + 10 - 25

- 3x = 15 - 3x - 15

- 3x + 3x = 15 - 15

0 = 15 - 15

0 = 0




Hope it helped,

A company has two large computers. The slower computer can send all the company's email in 35 minutes. The faster computer can c
Naddik [55]

The rate for the first is 1 job / 35 minutes and for the second is 1 job / 15 minutes.  So combined we get

r = 1/35 + 1/15

3×5×7r = 3 + 7 = 10

r = 10/(105) jobs per minute

We're interested in 1/r

1/r = 105/10 = 10.5 minutes per job

Answer: 10.5 minutes

If two trucks leave a given city on highways making an angle of 132 degrees with one another, traveling at 45 and 55 miles per h
Law Incorporation [45]

Answer:

183 miles to the nearest mile.

Step-by-step explanation:

Distance =Speed X Time

Distance of Truck B from point A=45 X2 =90 miles

Distance of Truck C from point A=55 X2 =110 miles

Angles between them, BAC=132°

We want to find the Distance BC denoted by a between the trucks.

Using Cosine Rule,

a²=b²+c²-2bcCos A

=90²+110²-(2X90X110XCos132°)

=33448.79

a=√33448.79

BC=182.89 miles

The distance between the trucks is 183 miles to the nearest mile.
