The first one is 75% i think I dont know if thats the answer though hold on and I'll get you the others
X+y=70
x=2y-5
x=larger number
y=smaller number
now plug in the value of x to only have one variable in the equation...
Way to solve for y:
(2y-5)+y=70
3y-5=70
add 5 on both sides...
3y=75
divide by 3 on both sides
y=25
1st way to solve for x:
now plug in y in the original equation...
x+25=70
subtract 25 on both sides...
x=45
2nd way to solve for x:
plug in y for the second equation...
x=25(2)-5
x=50-5
x=45
answer: the two numbers are 45 and 25.

Answer:</h3>
- sticker: $12,620
- dealer's cost: $10,712
<h3>
Step-by-step explanation:</h3>
The total cost of options is the sum of their individual costs.
total options = $542 +140 +318 +580 = 1580
The sticker price is ...
sticker price = base price + total options + destination charge
= $10600 +1580 +440
sticker price = $12,620
The dealer cost is ...
dealer cost = 82% × base price + 100% × total options + destination charge
= 0.82·$10600 +1580 +440
dealer cost = $10,712
Answer:
number 3 is 30, number 4 is 46 and the last one is 55
