X+x-x+y+y-z+z-z is equal to x+2y-z (combining like terms)
First, we set up our problem.
5/7+3/8.
Then we find our least common denominator.
Our LCD is 56.
We multiply what we did in the bottom to the top.
Here's our problem so far.
40/56+21/56
Next, we add 40 and 56.
40+21=61.
Now we have 61/56.
An improper fraction.
We simplify it.
Our final answer is 1 5/56. (Fully simplified)
Have a nice day! :)
Answer:
22,440
Step-by-step explanation:
204 = 2 * 2 * 3 * 17
1320 = 2 * 2 * 2 * 3 * 5 * 11
They both have 2 2's and a 3 in common, so use them once
2 * 2 * 3 * 17 * 2 * 5 * 11 = 22,440
Answer:
x = 1
y = -3/2
Step-by-step explanation:
Step 1: Arrange the equations with like terms in column.
Step 2: You want 1 set of coefficients that are opposites. This problem already has opposites: -2y and +2y.
Step 3: Solve for x.
4x-2y=7
3x+2y=0
--------------
7x = 7
x = 1
Step 4: Substitute the value of x and solve for y.
4(1)-2y=7
4-2y=7
-2y=7-4
-2y=3
y=-3/2
C. Divide the previous value by 5
