You reduce then evaluate the power. which would be 15-(-6+2+9)÷3-27. then you calculate and then work out the denominator and then divide. I got 13 2/3
Answer:
is this by any chance about simultaneous equations? If so,
Step-by-step explanation:
Step 1 is telling us to decide on whether x and y should be the unknown. For instance, you want x to be the unknown, so u solve for x.
Step 2 is telling us to write equations with x and y.
For example,
7x + 5y = 12
7x - 2y = 9
This may not be accurate but it is an equation.
Step 4 is telling us to check whether the solution is accurate or not. For instance, we say 7 is x. so we substitude 7 into the original equation to see whether the answer we found is correct.
For step 5, im not really sure.
hope this helps though???

Answer B
Step-by-step explanation:
I took the test and got it right
It is only asking for the 3/4 length buttons
There are 3 of them
Lining them up means adding them together
3/4 + 3/4 + 3/4 = 9/4, or 2 1/4
2 1/4 should be your answer
hope this helps
