From the text of the task we can write the following equation:

\frac{2x}{5}+\frac{x}{3}=22\\
\\
Solving: multiplying \ all \ terms \ by \ 15:\\
\\
6x+5x=330\\
\\
11x=330\\
\\
x=\frac{330}{11}\\
\\
\boxed{x=30}

<u>2/5 x + 1/3 x = 22</u>

First of all, I've been answering so many of these things lately that I'm
getting really tired of 'x'.  Let's call the unknown number ' Q ' instead.

<u>2/5 Q + 1/3 Q = 22</u>

Multiply each side by 5 :

2Q + 5/3 Q = 110

Multiply each side by 3 :

6Q + 5Q = 330

Add the like terms on the left side:

11Q = 330

Divide each side by 11 :

<u>Q = 30</u> .

Can someone please help me with this question please ?
EleoNora [17]

Answer:

x=43

Step-by-step explanation:

Since the lines are parrallel, the angle underneath the one you are finding is equal to 65. To find the total value of (x+72) you subtract 65 from 180, giving you 115.

x+72 = 115

then you subtract 72 from both sides

x=43

What is the solution to the system of equations?
s344n2d4d5 [400]

Answer:

(3,2)

Step-by-step explanation:

Here's your given:

y = 4x - 10

y = 2

Because they both equal y, that means they equal each other:

2 = 4x - 10

Add 10 on both sides:

12 = 4x

Then, divide 4 on both sides:

3 = x

This represents the x coordinate.

Normally you would put this value into one of the equations to figure out y, but they already gave us that in the beginning:

y = 2

This represents the y coordinate.

Put the two values together to get: (3,2)
