The reason fractions need a common denominator before adding or subtracting is so that the numbers of pieces you are adding/subtracting are all the same size. Note that the numerator of a fraction just tells you how many pieces you have of that size.
Answer:
1,300
Step-by-step explanation:
Order of operations tells us that we should do everything in parentheses first.
Multiplying out (4 x 300) and (4 x 25) gets
1200 + 100
From here, we add the two together to arrive at
1,300
22300 because the tenths place is below five
Answer:
y=0
Step-by-step explanation:
The equation for the slope is
m = ( y2-y1)/(x2-x1)
-2 = (4-y)/(1-3)
-2 = (4-y)/-2
Multiply each side by -2
4 = 4-y
Subtract 4 from each side
4-4 = 4-y-4
0 = -y
0=y
Answer:
24
Step-by-step explanation:
Convert the 2/5 into a decimal and multiply 0.40×60 to give you 24
