Please help! Which one is it!

Mathematics
1 answer:
vlabodo [156]3 years ago

As far as can see there are 2 correct methods shown, although there are other more efficient ways to solve this.

The 2 correct methods shown are:

{First, distribute}\ \frac{3}{4}\ to\ (x-8).\ {Then, subtract}\ 6\ from\ both\ sides.\ Finally,\ multiply\ both\ sides\\ by\ \frac{4}{3} .

and

First,\ multiply\ by\ \frac{4}{3}\ on\ both\ sides.\ Then,\ add\ 8\ to\ both\ sides.

The reason for this is because if we want to solve for "x", we must first isolate it. Normally we would isolate the "y variable", but because there is none in this equation we have to automatically assume that the "y" value has been given to us.

If you would like to see the math behind these 2 solutions I'll be more than happy to add it, if I can still edit my answer at that point in time. Also if you find out that this answer is wrong please tell me in the comments below, and I promise that I will come back and rework my math. Thanks!

A sales person earns a commission based on the number and type of vehicle sold. A person selling 6 cars and 3 trucks earns 4,800
AURORKA [14]
Assign variables to you unknowns.

c = $ cars
t = $ trucks

6c + 3t = 4800
8c + t = 4600

use substitution or elimination to solve the system of equations.

using elimination.. multiply second equation by -3 and add to the other to combine equations into one.

6c + 3t = 4800
-3(8c + t = 4600)
---------------------------
-18c + 0 = -9000
c = 9000/18
c = 500 $

use this in one of the equations to find the cost of a truck.

8(500) + t = 4600
4000 + t = 4600
t = 4600 - 4000
t = 600 $

question asks
2(500) + 3(600) =
1000 + 1800 = 2800 $

Two trains leave the station at the same, one heading west and the other east. The westbound train travels at 55 miles per hour.
Mars2501 [29]

The time that taken for the two trains is 1.2 hours.

The computation of the time taken for the two trains is shown below:

Given that

The westbound train travels 55 miles per hour.

And, the eastbound train travels 75 miles per hour.

So, the total speed is

= 55 miles per hour + 75 miles per hour

= 130 miles per hour

The distance is 156 miles

So, the time taken is

= \frac{distance}{speed}\\\\= \frac{156\ miles}{130\  miles\ per\ hour}\\\\

= 1.2 hours

Therefore we can conclude that the time that taken for the two trains is 1.2 hours.

Solve for y. -3/y=6 Simplify your answer as much as possible.
Molodets [167]
Solving for "y" means that we need to get y to be on one side of the equation. It should look like y= something. To get the y by itself, we need to get rid of that -3. To do that, we'll have to divide by -3 (because even though there's a y being divided, the -3 is still the numerator). 6/-3 is -1/2. Therefore your answer is y=-1/2

Systems of equations with graphing
OlgaM077 [116]

Answer:

x= negative 1 and 2/5 y=1 and 3/5

Step-by-step explanation:

1. Start by putting both equations into slope-intercept form.  (y=mx+b)

-3x+3y=9

-3x+3x+3y=9+3x

3y=9+3x

3y/3=9+3x/3

y=3+x

2x-7y=-14

2x-2x-7y=-14-2x

-7y=-14-2x

-7y/-7=-14/-7-2x/-7

y=2+2/7x

2. Graph the equations and find where they intercept.
