What is "x" in 4/5 times x equals 2/5

1 answer:

5 0

The equation looks like this right now: 4/5x=2/5. In order to solve for x, you need to divide both sides by 4/5. When dividing fractions, you need to remember the rule KCF (keep, change, flip) So, you will keep the first fraction, change the division sign to a multiplication sign, and flip the last fraction. Now you have 2/5*5/4. When you do that, you get 10/20. Simplify it, and you end up with 1/2, and that is your answer. I hope that helped! :)

Do the ratios 4/5 and 12/20 form a proportion?

yKpoI14uk [10]

Answer:

No. They are not in proportion

Step-by-step explanation:

$\sf \dfrac{4}{5} \ \text{is in the simplest form}$

$\sf \text{Simplest form of $\dfrac{12}{20}$} = \dfrac{12 \div 4}{20 \div 4}=\dfrac{3}{5}$

So, they are not in proportion

Rewrite the equation for x, and express its value in terms of a. 3/a x - 4 = 20

My name is Ann [436]

For this case, we must clear variable "x" from the given equation, expressed in terms of "a".

We have:

3/a x-4=20

By clearing "x" we have:

Adding 4 to both sides of the equation:

3/a x = 20 + 4

Multiplying by a/3 on both sides of the equation:

x=24a/3

x=8a

So, x=8a

Answer:

x=8a

A golf tournament has five rounds. The players are given scores for each round based on how many strokes they are above or below

frozen [14]

We have the following table:

Round Number of Strokes Above or Below 72

1 -5

2 +6

3 -2

4 -4

5 +5

So, the expression that represents the total number of strokes is:

72 + (Number of strokes Above or below 72)

Therefore, for every round we get:

Round Number of Strokes Above or Below 72 Total number of strokes

1 -5 72 - 5 = 67

2 +6 72 + 6 = 78

3 -2 72 - 2 = 70

4 -4 72 - 4 = 68

5 +5 72 + 5 = 77

The total number of strokes is:

67 + 78 + 70 + 68 + 77 = 360

Additionally, the average is the total number of strokes divided by the number of rounds, so it is equal to:

$\frac{360}{5}=72$

Answer: Total: 360 Strokes

Average: 72 Strokes
