Solve 5kx + 6 = 7kx for x.

Mathematics
1 answer:
Slav-nsk [51]3 years ago
4 0

Answer:

5kx + 6 = 7kx  

 

Subtract 6 on both sides  

 

5kx + 6 - 6 = 7kx - 6

5kx = 7kx - 6

 

Then subtract 7kx on both sides

5kx - 7kx = 7kx - 6 - 7kx  

-2kx = -6  

 

Now divide by -2k on both sides

-2kx/-2k = -6/-2k

x = -6/-2k

Simplify

x = 3/k  

These are algebriac equations that you keep doing. Maybe try practicing the simpiler algebriac equations then slowely do more complicated ones. Just letting you know.

Which possibly forms a triangle
svp [43]

Answer:

C. 17, 12, 7

Step-by-step explanation:

In a triangle, the sum of the lengths of any two sides must be greater then the length of the third side. If you can show any two segments, the sum of whose lengths is less than the length of the third segment, that cannot form a triangle.

In choices A, B, and D, there is at least one sum of the lengths of two segments that is less then the length of the third segment. That shows that choices A, B, and D cannot form triangles.

A. 8 + 7 = 15 < 16 No

B. 9 + 7 = 16 = 16 No

D. 11 + 5 = 16 < 17 No

C.

17 + 12 = 29 > 7

12 + 7 = 19 > 17

17 + 7 = 24 > 12

Yes

PLEASE HELP! THANK YOU!<br><br> Explain your answer!!!
Brrunno [24]

Answer:

1) y = 1/2 x + 3 and y = 1/2 x  are parallel

2) y = 1/2 x + 4   and   y = 1/2 x + 1  are parallel

Step-by-step explanation:

Two lines are parallel only if their slope is equal.

1)

In the first problem:

y = 1/2 x + 3 and y = 1/2 x have same slope ( i.e slope = 1/2)

That means these two equations are parallel to each other.

2)

In the second problem:

y = 1/2 x + 4   and   y = 1/2 x + 1 have same slope( i.e slope = 1/2)

Hence above two equations are parallel to each other.

Jose earns $9 commission for every phone and $4 commission for every accessory he sells. On a given day Jose makes $253 in commi
andrezito [222]

Answer:

9p + 34a = 253 and p + 8= a are the two required equations which will give us the number of phones and accessories sold by Jose

Step-by-step explanation:

Let us denote the number of phones as ‘p’ and number of accessories as ‘a’ So, we can write the following equations from the given data:

Given that levi made $ 253 commission

<u>9p + 4a = 253 (1) </u>

And,  Jose sold  sold 8 more accessories than phones. So we can frame a equation as follows:

<u>p + 8 = a (2)</u>

These two equations can be used and solved to determine the number of phones and accessories sold.
