Answer:

A) 12.

Step-by-step explanation:

Plug in 12 for x in the given equation:

x/4 + 9 = x

(12)/4 + 9 = 12

Simplify. Remember to follow PEMDAS. First, divide, then add:

(12/4) + 9 = 12

(3) + 9 = 12

12 = 12 (True).

I would like to know what 1.34 as a fraction in simplest form would be
Paha777 [63]
1.34 = 1 \dfrac{34}{100} = 1 \dfrac{34 \div 2}{100 \div 2} = 1 \dfrac{17}{50}





-------- Edited to include more explanation --------------

1.34 = 1 whole 34 hundredth 

\text { 1 whole 34 hundredth written as a fraction =} 1 \dfrac{34}{100}

Then we simplified it by dividing the numerator and the denominator by 2:

1 \dfrac{34}{100}  = 1 \dfrac{34 \div 2}{100 \div 2}

34 divided by 2 will give us 17 and 100 divided by 2 will give us 50:

1 \dfrac{34 \div 2}{100 \div 2} = 1 \dfrac{17}{50}

16. ∠2 = 53° because it is supplementary.

- You are given the measurement of ∠1, which is 128°. From the picture you can see that ∠1 and ∠2 combined equal 180° (they are supplementary angles).
- So to find ∠2, simply subtract 128° from 180°. The answer is 53°.

------------------------------------------------

17. 12° because it is vertical.

- Vertical angles, like 48° and 4x in the image, are always equal.
- So if 4x = 48°, then you can divide both sides to get  x = 12°.

kotykmax [81]
To solve this relationship simply make them equal to each other and find the correct value to multiply both the top and cotton numbers and solve,
In this case because of the initial ratio of 1:9, if the bonsai ficus is 6 then 54 inches would be the full size.
