When adding fractions that have the same denominator (the number on the bottom), you simply add the numerators together and keep the denominator the same. So 7/10 + 4/10 = (7+4)/10 = 11/10 which is the same as 1 1/10
The answer is 20.679. Make sure to line up the decimal points before adding.
Divide both sides of the equation by -2 to get the y variable by itself, this will yield the equation y = -4.
When adding or subtracting equations with variables, you keep the variable as a unit. Think of the variable y as "apples", then the equation becomes 7 apples + 1 apple = 8 apples (or 8y)
Answer is 5 x 5 x 5 = 125, so none of the shown answers is correct
15% is equivalent to 15/100 or 0.15. You find 15% of 40 by multiplying 40 x .15 = 6
