The answer is -3, Choice 1 because you only need to care about the x values, so what do you add/subtract from 8 you get 5? So the answer is -3

Answer:

A) -3

Step-by-step explanation:

Given,

When (8x + 12y) is added to (ax − 6y) the answer is (5x + 6y)

(8x+12y)+(ax-6y)=(5x+6y)

8x+12y+ax-6y=5x+6y

(8+a)x+6y = 5x+6y      ( By combining like terms )

By comparing,

8+a = 5

\implies a = 5 - 8 = -3

Hence, the value of x is -3,

Option A is correct.

<h3>You should pick:</h3>

The relationship is linear because each y-value is 5 more than the one before it.

<h3>Here's why I think so:</h3>

If we look at the relationship between the x values and the y values, we can tell that they both increase periodically. The x values increase by 1('s), while the y values increase by 5('s).

Think about it. If y starts off at 5 when x is at 0, and then goes to 10 by x becomes 1, and increases another 5 values when x increases by 1 (again), then we are witnessing a pattern. For every 1 x value, y increases by another 5 values. Such a repetitive relationship will clearly be shown with a line. Thus, the relationship is a linear one.

Since we know that the relationship of the table is linear, and that it is linear due to the fact that the y-value continuously increase by 5's without fail, the only answer that would make sense is the second one.

<em>Therefore, the answer is '</em><u><em>The relationship is </em></u><u><em>linear </em></u><u><em>because each y-value is 5 more than the one before it.</em></u><em>'</em>

A 4.3 ounce tomato has about 24 calories. How many calories are in one ounce ?
mafiozo [28]

Answer: approximately 5.5814 calories

==================================

We start off with this ratio

4.3 ounces : 24 calories

Divide both parts of the ratio by 4.3 so that we end up with 1 ounce on the left side

4.3 ounces : 24 calories

4.3/4.3 ounces : 24/4.3 calories

1 ounce : 5.5814 calories

This value is approximate to four decimal places.

2/4, 4/8, 2/5, 7/14
Oduvanchick [21]
2/4 --> Once simplified by dividing each fraction part by 2 can get 1/2 

4/8 --> Once simplified by dividing each fraction part by 4 can get to 1/2 

2/5 --> Cannot be simplified by any numbers 

7/14 --> Once simplified by dividing each fraction part by 7 can get to 1/2 

---------

2/5 is not equal to 1/2 <span>✔</span>
