paul paints a room in 6 hours. joel paints the room in 3 hours. how long will it take them to paint togather?

Answers

Paul paints 1/6 of the room each hour.
Joel paints 1/3 of the room each hour.

Working together, they paint (1/6 + 1/3) of the room each hour.

In order to add the fractions, you need a common denominator.
6 will work:

(1/6 + 1/3) = (1/6 + 2/6) = 3/6 = 1/2

Together, they can paint at the rate of 1/2 room/hour .

This rate of work produces 2 hour/room.

$(1)/(6)+(1)/(3)=(1)/(x)\n (1)/(6)+(2)/(6)=(1)/(x)\n (3)/(6)=(1)/(x)\n (1)/(2)=(1)/(x)\n x=2$

2 hours

Angela scored 15 points less than twice the lowest score on a math test. If her score was95, what was the lowest score on the test?

Answers

Answer:

Step-by-step explanation:

To find the lowest score on the math test, we can set up an equation based on the information given.

Let's denote the lowest score as "x".

According to the information given, Angela scored 15 points less than twice the lowest score.

Twice the lowest score is 2x, and Angela's score is 15 points less than that, so her score can be represented as 2x - 15.

Given that Angela's score is 95, we can set up the equation: 2x - 15 = 95

To solve for x, we can add 15 to both sides of the equation: 2x - 15 + 15 = 95 + 15

Simplifying, we have: 2x = 110

Finally, we can divide both sides of the equation by 2 to isolate x: 2x/2 = 110/2

Simplifying further, we get: x = 55

Therefore, the lowest score on the math test was 55.
