What is this and how do i solve

Mathematics
1 answer:
Troyanec [42]4 years ago
8 0

Answer:

<h2>x = 20</h2>

Step-by-step explanation:

The angles 7x° and (x + 20)° are supplementary angles.

Supplementary angles add up to 180°.

Therefore we have the equation:

7x + (x + 20) = 180

7x + x + 20 = 180            <em>subtract 20 from both sides</em>

8x = 160         <em>divide both sides by 8</em>

x = 20

Please answer the following questions I will give out brainliest!!!
riadik2000 [5.3K]
Question 14:
We are given that:
C = πd
To solve for d, we need to isolate the d on one side of the equation. This means that we need to get rid of the π next to the d.
In order to do so, we can simply divide both sides of the equation by π as follows:
C/π = πd/π
d = C/π .........> The first option 

Question (15):
We are given that:
d = rt
To solve for r, we need to isolate the r on one side of the equation. This means that we need to get rid of the t next to the r.
In order to do so, we can simply divide both sides of the equation by t as follows:
d/t = rt/t
r = d/t.........> The third option 

Hope this helps :)

Find the mistake in the following : 3 x ( 4 + 2 ) = 12 + 2
Lyrx [107]

Answer: The mistake is improper use of distribution property.

Step-by-step explanation:

It is given that 3\times (4+2)=12+2.

We need to find the mistake.

The given expression is

3\times (4+2)

Using distribution property, we get

3\times (4)+3\times(2)

12+6

So, 3\times (4+2)=12+6.

In the given calculation the 3 is not distributed properly because 3 is not multiplied with 2.

Therefore, the mistake is improper use of distribution property.
