Answer:
x=19, DE=84, EF=36
Step-by-step explanation:
Since the total value of DF is 120, DE and EF must add up to 120. Therefore:
4x+8+2x-2=120
Combine like terms:
6x+6=120
Divide both sides by 6:
x+1=20
Subtract 1 from both sides:
x=19
This means that DE is 4(19)+8=84, and EF is 2(19)-2=36.
Hope this helps!

Answer: 0.98 cents
Step-by-step explanation:
First you want to get the amount of apples to one pound.
3.5 to 1
3.5 divided by 3.5 equals to one.
Now you need to o the same thing to the cost

0.3:0.1
Step-by-step explanation:
first convert the % to decimals.
75%=0.75
25%=0.25
then look for a common factor and divide be that, in this case its 5.
0.75/5=0.15
0.25/5=0.5
now since these arent in the simplified form, you gotta divide again by 5.
0.15/5=0.3
0.5/5=0.1
