87% i think but don't hold me to that
you just do 65/5=13% so 13% is missing so you take that from 100 which gives 87
This is the answer. Let me know if i'm correct.
Step-by-step explanation:

<h3>Given</h3>
- Equation ax² + bx + c = 0
- One of the roots is twice the other
<h3>To find</h3>
<h3>Solution</h3>
Let the roots be p and q
<u>The sum and product of the roots:</u>
<u>The sum of the roots, considering p = 2q,</u>
And
<u>The product of the roots, considering p = 2q:</u>
And
<u>Substitute q with -b/(3a)</u>
- 2(-b/(3a))² = c/a
- 2b²/(9a²) = c/a
- 2b² = 9a²(c/a)
- 2b² = 9ac

<h3>Given</h3>
Quadratic equation
- ax² = bx + c = 0, with equal roots
<h3>To find</h3>
<h3>Solution</h3>
<u>Equal roots means the discriminant is zero:</u>
- D = √b² - 4ac
- √b² - 4ac = 0
- b² - 4ac = 0
- b² = 4ac
Answer:
Car 1 - 25
Car 2 - 30
Step-by-step explanation:
Assuming we use car 2 as much as possible than car 2 consumed 30 gallons while car 1 consumed 25
(35x30)+(15x25)=1425
30+25=55
Sorry if this is wrong. I tried my best, if it is wrong than tell me so I will know and can try to improve.
The least common multiple of six and three is six multiply the numerator and denominator of each fraction by whatever value will result and the denominator of each fraction being equal to the least common factor which is six.
When they have like denominators which is the same ones you can add
1/6+2/3
1/6+2/3 times 2 by 2 and 3 by 2 with the 2/3 fraction
Then u get 1/6+4/6
=1+4/6
=5/6
Mark brainliest if I helped/answer correct !
