The length of hours Gilbert drove is 7.5 hours.
The length of hours Brian drove is 4.1 hours.
<u>Step-by-step explanation</u>:
- Gilbert averaged = 45 miles per hour
- Brain averaged = 65 miles per hour
- Total hours = 11.6 hours
- Total distance = 604 miles
Let 'x' be the hours Gilbert drove.
Let 'y' be the hours Brian drove.
x+y = 11.6 -----(1)
45x+65y = 604 -----(2)
Multiply (1) by 45 and subtract (2) from (1)
45x+45y = 522
-(<u>45x+65y = 604</u>)
<u> -20y = -82 </u>
y = 82/20
y = 4.1 hours
The length of hours Brian drove = 4.1 hours
Substitute y=4.1 in (1)
x+4.1 = 11.6
x = 7.5 hours
The length of hours Gilbert drove = 7.5 hours
Answer:
Three terms, which makes this expression a trinomial.
5x²-4x -12
Step-by-step explanation:
(5x + 6)(x-2)
5x² -10x + 6x -12
5x²-4x -12
50-10=40 then you would divide 40 by 3 so... it would be 13 banana's.
Answer:
Step-by-step explanation:
2x > 10 Divide by 2
2x/2 >10/2
x > 5
x cannot be 5 or anything smaller.
In English, x >5 reads as x must be greater than 5. (It can't be equal to 5 because 5 is not greater than 5)
The only two items that work are
8 which is greater than 5 and
30 which is also greater than 5

Answer:
- 2/5 cups oats per cup water
- 2.5 cups water per cup oats
Step-by-step explanation:
The denominator of the fraction is the unit you want 1 of.
(6 cups oats)/(15 cups water) = (6/15) cups oats/(1 cup water)
= (2/5 cups oats)/(1 cup water)
1 cup of water would need 2/5 cups of oats.
__
Obviously, the other ratio is the reciprocal of this.
(1 cup water)/(2/5 cups oats) = (5/2 cups water)/(1 cup oats)
1 cup of oats would need 2.5 cups of water
