1/2 × 40 = 2x + 8
⇔ 20 = 2x + 8
⇔ 12 = 2x
⇔ x = 6
Answer: C) 12
Step-by-step explanation:
This problem makes use of Cross Multiplying.
Simply do:
2x*3y=9*8
6xy=9*8
6xy=72
xy=12

This answer is 1.1.
It is because:
5 goes into 5.5 ... 1.1 time. You would divide each 5 by 5 and then put the decimal in the middle.
On a model it would be something like this, 5 sections of 100 and 10 combined together.
Take a closer look!
Draw 6 100 by 100 graphs,
Color in 5 and 50 hundredths of the models.
Divide the colored sections by 1 and 10 hundredths.
Key:
The models are the 6 squares.
The 5.5 is the color red
The black is the division of 1.1
Hope this helps:
X = 8/15
6x - 1/5 = 3/1
6x - 1/5 = 3
6x = 3 + 1/5
6x = 15 + 1 over 5
6x = 16/5
x = 16/30
Then, you simplify.
x = 8/15
Answer:
the one with the most parts citric acid
Step-by-step explanation:
