Answer:
The answer is A :)) hehe.
Answer:
The number is 8.
Step-by-step explanation:
Rewrite the word problem as an equation.
The sum of (we will be adding.), half of a number (we can use x, this will be written as x/2.) and double the number (this will be written as 2x) is 20.
To find the number, solve the equation.
x/2 + 2x = 20
Multiply both sides by 2.
x + 4x = 40
Combine terms.
5x = 40
Divide both sides.
x = 8.
For this case we propose a rule of three to obtain the number that represents 25% of 37.
So, we have:
37 --------> 100%
x -----------> 25%
Where "x" is the number that represents 25% of 37.

Finally, we have that 25% of 37 is 9.25.
Answer:
25% of 37 is 9.25.
1.) (9*2)-(9*-1)
2.)4*(9+1)
3.)A:GCF=5
B:5*(20-15)
4.) 7x+14
