First we should calculate the relation between how much they make and the fuel cost so we write
(1412.42+<span>1187.92)/418.91=6.21
So that means that for every 6.21 dollars made 1 dollar of fuel must be deducted so now we calculate what they need to be deducted by:
Dan deduction = 1412.42/6.21= 227.41
Aaron deduction= 1187.92/6.21 = 191.29</span>
Answer:
(-2 , -3) and (0.6 , 4.8)
Step-by-step explanation:
y=3x +3
(x - 2)² + y² = 25
(x - 2)² + (3x +3)² = 25
x²-4x+4+9x²+18x+9-25=0
10x²+14x-12=0
5x²+7x-6=0
(x+2)(5x-3)=0
x = -2 or x = 3/5 (-0.6)
y = -3 or y = 4 4/5 (4.8)
D. <span>Colby and Sarah sold newspapers this past summer. Colby earned $4.50 for each newspaper he sold. Sarah's earnings were $35 less than Colby's at the end of the summer. The following expression shows Sarah's earnings:
4.50y − 35</span>
I would be E and C

Answer:
Javier,16,12
Step-by-step explanation:
From the first bag, we can pull a 1,2 or 3. That would go on the first line of the tree diagram
From the 2nd bag, we can draw a 4,5, or 6. That goes on the the second line under each number
From the 3rd bag, we can draw a 7,8, or 9. That goes on the the third line under each number
Javier drew the correct tree diagram.
1,3,5,7,9 are odd numbers. We must have at least 2 of these numbers
1,4,7 2,5,7 3,4,7
1,4,9 2,5,9 3,4,9
1,5,7 3,5,7
1,5,8 3,5,8
1,5,9 3,5,9
1,6,7 3,6,7
1,6,9 3,6,9
There are 16 total where there are at least two odd numbers
Multiples of 4 are 4 and 8
We must have either a 4 or an 8 but not both
1,4,7 2,4,7 3,4,7
1,4,9 2,4,9 3,4,9
1,5,8 2,5,8 3,5,8
1,6,8 2,6,8 3,6,8
There are 12 outcomes
