28 = 3x+4x
x = 4
3x = 12
4x = 16
12:16 = 3:4
<span>X= math problems
y= science problems
x +y =42
x= y+10
Substitute: (y+10) + y =42
Combine y: 2y +10=42
Solve for y: y= 16
There are 16 science questions and 26 math questions</span>
So if you wanted the factored form (exg. 1*2*3*4=24)
then this is (5 times 5 times 7)
48 qrts * 25 barrels per trip = 1200 qrts get picked up per trip
1200 qrts * 1 hr/7qrts = 171.43 hrs to fill all 25 barrels
171.43 hrs * 1 day/24hrs = 7.14 days
IF I want to rent the paddleboat I have to start with $10 and I have it for an hour it will be 18$. We are increasing by 8 for every hour we have the boat
c = 8h + 10
