To solve this question simply find the common denominator or the same number for the denominator for all 3 fractions by multiplying both the top and bottom number for the fractions that do not have the largest bottom number which is 12.
1/2 = 6/12 is you multiply the top and bottom by 6
3/4 = 9/12 is you multiply the top and bottom by 3
6/12 + 9/12 + 3/12 = 18/12 = 1 6/12 = 1 1/2.
The correct answer is C.
Answer:
First number 2
Second number 1
Step-by-step explanation:
Let the first number = x
Let the second number = 3x - 5
Equation
x + 3x - 5 = 3
Solution
x + 3x- 5 = 3 Combine
4x - 5 = 3 Add 5 to both sides
4x - 5 + 5 = 3 + 5 Combine
4x = 8 Divide by 4
4x/4 = 8/4 Combine
x = 2
3x -5 = 3(2)- 5 = 1
PEMDAS
When solving an equation we do them in reverse order
AS adding and subtracting
MD multiplication and division
E exponents
Basically we are trying to get the variable alone.
12=10-3x
subtract 10 from each side
then divide by -3 on each side
3/5 x -12 = 18
first add 12 to each side
then multiply by 5/3 to each side
Answer:
(-6127) + 0 = (-6127)
(+18) + 2 = (+20)
(+27) - 7 = (+20)
(+63) + (-13) = (+50)
(+21) - 4 = (+17)
