A system of linear equations is shown below 5x = 3y - 2
y= x + 4
What is the x-coordinate of the solution?

A. 2
B. 4
C. 5
D. 1

Answers

Answer 1

Answer: If you would like to find the x-coordinate of the solution, you can calculate this using the following steps:

5x = 3y - 2
y = x + 4
_________
5x = 3 * (x + 4) - 2
5x = 3x + 12 - 2
2x = 10
x = 5

The correct result would be C. 5.

How is the process of finding equivalent ratios like the process of finding equivalent fractions?

Answers

It's generally the same, because each ratio can be written as a fraction and each fraction can be written as a ratio. For example:

1 : 2 = 1/2
5 : 7 = 5/7
3.5 : 4.3 = 3.5/4.3 = 35/43
etc.

Finding equivalent ratios is just multiplying or dividing both sides by the same number. Finding equivalent fractions is multiplying or dividing both numerator and denominator by the same number, so it's the same. For example:

1 : 2 = 2 : 4
1/2 = 2/4

5 : 7 = 10 : 14
5/7 = 10/14

3.5 : 4.3 = 7 : 8.6
35/43 = 70/86

etc.

Answer: On Friday, he spend the least amount of time on the running machine.

Step-by-step explanation:

Since we have given that

Monday 0.3 = $0.3* 100\%=30\%$

Tuesday = 15%

Wednesday = $(1)/(6)* 100\%=16.67\%$

Thursday = $0.2* 100\%=20\%$

Friday = $(1)/(8)* 100\%=12.5\%$

Hence, we can compare all the days, and we get that

On Friday, he spend the least amount of time on the running machine.
