Answer:
students.
Step-by-step explanation:
We have been given that of the students that attended Roosevelt Elementary 6/8 of the school play a sport. Of the students are playing a sport 3/5 of the students are also involved in the drama club.
To find the students are both play a sport and a part of the drama club, we need to find 3/5 part of 6/8 as:




Therefore,
students play sport and part of the drama club.
Divide both sides by 5
4x + 7 = 59
Subtract 7 on both sides
4x = 52
Divide 4 on both sides
x = 13
Answer:

Step-by-step explanation:
<em>Hey there!</em>
<em />
In most cases "the number" would be x.
So if the statement says 8 <u><em>"more than a number",</em></u>
It is saying 8 plus x or 8 + x.

Answer:

Step-by-step explanation:
The standard form is called the scientific notation expressed generally as;

A is an integer between 1 and 10
n is ant integer or fraction
Given the decimal value 98.704, we ill shift the decimal point to the back once to have;
98.704 = 
<u>Note the when the decimal point is shifted backwards the value of n is always positive</u>. Hence the expansion in power of 10 is 
If she went 10 miles upstream in the same time as she went 20 miles downstream, that means the downstream speed is twice the upstream speed.
The speed is still water is 9 mph.
The speed of the current is c.
Going downstream, the current adds speed, so the sped downstream is 9 + c.
The speed upstream is 9 - c.
9 + c is twice 9 - c.
9 + c = 2(9 - c)
9 + c = 18 - 2c
3c = 9
c = 3
Answer: The speed of the current is 3 mph.
Check:
9 + c = 12
9 - c = 6
By taking into the account the speed of the current, the downstream speed, 12 mph, is indeed twice the upstream sped, 6 mph.
