<span>3/5 + 7/10 = 6/10 + 7/10 = 13/10 = 1 and 3/10 lbs. needed
She has 4/5 *3/1 bags = 12/5 = 2 and 2/5 pounds
2 2/5 - 1 3/10 = 2 4/10 - 1 3/10 = 1 and 1/10 pounds left over
Hope I helped:P</span>
Answer:
Step-by-step explanation:
you can think of it backwards,
-50 = 3x - 8y
x = 6y
X x 3 = 3x
6y x 3 = 18y
3x = 18y
18y - 8y = -50
10y = -50
y = -5
6 x -5 = -30
x = -30
Draw out a number line. Make sure -28 is on the number line, along with other optional values (such as 0 perhaps). At -28, plot an open circle or hole. This indicates this value is not part of the solution set. This is because there is no "or equal to" as part of the inequality sign. Then shade to the left to indicate values smaller than -28.
So in summary, you'll have an open hole at -28 and shading to the left.
The mode is the most common number in a series of given numbers. If 85 was the mode it would mean that it had to occur the most out of any other number. So it has to be 85.
