3(5y + 6) - 4
First, distribute so that it will make the solving easier.
Second, since parentheses indicate multiplication, '3 × 5y = 15y'.
Third, multiply '3 × 6' to get '18'.
Fourth, subtract '18 - 4' to get '14'.
Answer:
C) 15y + 14
Let's imagine the integers are a, b, and c. Since we know the sum of these numbers is 50 more than the smallest (which is a), our equation would look like this:
a + b + c = a + 50
We need a common variable, though, which we don't have right now. Since we know that these are 3 consecutive <em>even </em>integers, we know that:
b = a +2, which means that the second number is 2 more than the first number.
Using that same logic, we know that c = b +2 and since we know what b equals, we can sub that into this:
c = b + 2
c = (a + 2) + 2
c = a +4
So now instead of having this:
a + b + c = a + 50
We have this:
a + (a + 2) + (a + 4) = a + 50
3a + 6 = a + 50
Subtract a + 6 from both sides:
3a + 6 - (a + 6) = a + 50 - (a + 6)
2a = 44
Divide both sides by 2
2a/2 = 44/2
a = 22
The smallest integer is 22 which means the set would be:
22, 24, and 26
Adding or subtracting both sides
It is equal to 5/10 or it is equal to 50%
Answer:
x=4
Step-by-step explanation:
x/3-1/2=5/6
Add 1/2 to each side
x/3-1/2+1/2=5/6+1/2
x/3 = 5/6+1/2
Get a common denominator on the right
x/3 = 5/6+3/6
x/3 = 8/6
x/3 = 4/3
Multiply each side by 3
x/3 *3 = 4/3*3
x = 4
