Answer:
24.75 = 3*4.50 + x*4.50
x= 2.5 pounds of Granny Smith apples
Step-by-step explanation:
Gala apples = 3 lbs
Granny apples = x lbs
They cost 4.50 a pound
Total cost = 24.75
Total cost = gala apples * cost per pound + granny apples * cost per pound
Substitute in what we know
24.75 = 3*4.50 + x*4.50
24.75 = 13.50 + 4.5x
Subtract 13.50 from each side
24.75-13.50 = 13.50-13.50 + 4.5x
11.25 = 4.5x
Divide by 4.50 on each side
11.25/4.5 = 4.5x/4.5
2.5 =x
7x = -36+10x
X=12
You minus the 10 from 7 (7-10=-3) (-36/-3) gives you 12

Answer:
Decrease
Step-by-step explanation:
So, I encourage you to grab a calculator and see for yourself
Put in the function: 4/5 into a standard calculator. You will see that it will come out to .8
Put in the function: 3/5 into a standard calculator. You will see that it will come out to .6
.6 is less than .8, just as 3/5 is less than 4/5.
Another analogy that can be used is seeing the fraction as a real-life object.
Let's say that you make two pies. You cut the pie evenly into five slices. You set them on the table and leave them for whoever wants to eat them. You see that Pie 1 has two slices missing (3/5) and that Pie 2 has one slice missing. (4/5)
3 out of 5 slices are left of Pie 1.
4 out of 5 slices are left of Pie 2.
Pie 1 has less than Pie 2 does.
Hope this has helped!
