48% of 25 is 12. I hope this helps
The answer is c because 1.5 times 1 = 1.5 then you add 2.5 to get 3.5
Answer:
Population: All adults in the country
Sample: The 1,003 adults selected
Step-by-step explanation:
The sample always is a little part of the whole population. This part is the one that you are going use to study and make all the calculations (Example:average, median, percentage, standard deviation).
In that way, the sample represents all the population but is not the population, it's just a part.
Simplifying
0x + 7 + 5x = 2x + 30 + 40
Anything times zero is zero.
0x + 7 + 5x = 2x + 30 + 40
Combine like terms: 0 + 7 = 7
7 + 5x = 2x + 30 + 40
Reorder the terms:
7 + 5x = 30 + 40 + 2x
Combine like terms: 30 + 40 = 70
7 + 5x = 70 + 2x
Solving
7 + 5x = 70 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
7 + 5x + -2x = 70 + 2x + -2x
Combine like terms: 5x + -2x = 3x
7 + 3x = 70 + 2x + -2x
Combine like terms: 2x + -2x = 0
7 + 3x = 70 + 0
7 + 3x = 70
Add '-7' to each side of the equation.
7 + -7 + 3x = 70 + -7
Combine like terms: 7 + -7 = 0
0 + 3x = 70 + -7
3x = 70 + -7
Combine like terms: 70 + -7 = 63
3x = 63
Divide each side by '3'.
x = 21
Simplifying
x = 21
I'm guessing you want it factored since there is no solution. I got -3y+15 and its factored form would be -3(y-5).
