Answer:

<h3>The numbers are 20 and 9 </h3>

Step-by-step explanation:

Let the first number be x

Let the second number be y

<u>For the first equation </u>

One number is 7 less than 3 times the second number is written as

x = 3y - 7

<u>For the second equation</u>

The sum of the two numbers is 29

So we have

x + y = 29

Substitute the first equation into the second one

That's

3y - 7 + y = 29

4y = 29 + 7

4y = 36

Divide both sides by 4

<h3>y = 9</h3>

Substitute y = 9 into x = 3y - 7

That's

x = 3(9) - 7

x = 27 - 7

<h3>x = 20</h3>

The numbers are 20 and 9

Hope this helps you

Since the question is incomplete, answer will be subjective. An example of Evaluating Expressions is find h + 8 − 9 j − h; where h = 7 and j = 5.

<h3>What is the Evaluating Expressions?</h3>

The evaluating expressions  is known to be a form of digital and printable board work that can help students in working on substituting values in terms of variables of an algebraic expression.

Evaluating the Expression below:

h + 8 − 9 j − h;

Therefore, where h = 7 and j = 5

7+ 8 − 9 (5) − 7.

SO: 7 + 8 - 45 -7

=  -37

Therefore the answer to the Evaluating Expression is -37.

Triss [41]
<h3>Answer:</h3>

25°

<h3>Step-by-step explanation:</h3><h3></h3>

<em>Angles in a circle add up to 360°</em>

5a + (a + 60) + (2a + 100) = 360

5a + 3a + 160 = 360

5a + 3a = 8a

8a + 160 = 360

<em />

<em>Make a the subject</em>

8a + 160 = 360

8a = 200

200 ÷ 8 = 25°
