Combined rates
Susan = 2 car / 3 hr
= 2/3
Joe = 3 car / 4 hr
= 3/4
add the rates to get the new combined rate as 17 cars in "t" hours.
2/3 + 3/4 = 17/t
Need common denominator
2/3(4/4) + 3/4(3/3) = 17/t
8/12 + 9/12 = 17/t
17/12 = 17/t
see that "t" is 12 hours
1/4 divided by 3. Dividing by a number is the same as multiplying by its reciprocal.
So it's the same as 1/4 * 1/3. And when multiplying fractions you just multiply the numerator and denominator of each straight across.
(1*1)/(4*3) = 1/12
6.708 / 78. I would just type it into the calculator. You get 0.086
3 in 350 is 3 hundred
3 in 403 is 3
3 hundred is 100 times of 3
Answer:
y=-2x-94
Step-by-step explanation:
You can do anything with the y-intercept. The line is parallel (same slope) and the y-intercept can be literally any number in the world. I would advise to not use negative or positive infinity though.
