Step-by-step explanation:
Given:
Fifty-six students in a gymnastics club participated in the last fundraiser.
In the gymnastics club 80% of the students in the club participated in the fundraiser.
Now, to find the total number of students in the gymnastics.
Let the total number of students be
Number of students participated in the club = 56.
Percent of students participated in the club = 80%.
According to question:
<em>Dividing both sides by 0.8 we get:</em>
Therefore, the total number of students in the gymnastics are 70.

Answer:
1/3
Step-by-step explanation:
When working with balanced expressions (stuff on both sides of the equal sign), "what you do to one side, you do to the other", which keeps it balanced.
The first thing we notice is the exponent 1/4, which is one both sides, so we can get rid of it on both sides by using the <u>reverse operation</u>.
The reverse of exponents is <u>square root</u>.
Isolate x to solve. Separate the variables and non-variables.
4x + 10 = 9 + 7x
4x - 4x + 10 = 9 + 7x - 4x Subtract 4x from both sides
10 = 9 + 3x
10 - 9 = 9 - 9 + 3x Subtract 9 from both sides
1 = 3x Divide both sides by 3 to isolate x
x = 1/3 Answer
