Answer:
15(
+b) or
15(b+)
Step-by-step explanation:
First we can subtract the 4.
458 + 15b
Now we need to find the GCF, but they do not share any kinds of factors together. This might look ugly, but it is what it is. We factor out 15 to get b by itself.
15(+b) or
15(b+)
Answer: (-1,4)
Step-by-step explanation:
y=-2x+2 y=7x+11 <----- substitute this equation for y in the
equation y=-2x+2
7x+11=-2x+2 Add 2x to both sides
9x+11=2 Subtract 11 from both sides
9x=-9 Divide both sides by 9
x=-1
y=-2(-1)+2 Plug in x to one of the equations, I chose y=-2x+2
y=2+2 because it was the easiest, then solve
y=4
Solution is (-1,4)
Answer:
14 4/9 cans
Step-by-step explanation:
We need to add the cans used on Saturday and Sunday
10 7/9 + 3 4/6
We can simplify the fraction 4/6 by dividing the top and bottom by 2
10 7/9 + 3 2/3
To add, we need the fractions to have a common denominator of 9
10 7/9 + 3 2/3*3/3
10 7/9 + 3 6/9
Add the whole numbers 10 +3 = 13
Add the fractions 7/9 + 6/9 = 13/9
13/9 = 1 4/9
Move the whole part of the fraction to the whole numbers
13 + 1 + 4/9
14 4/9
