We just have to find the closest number that can be multiplied by 32 and still be under 300. Do this by following this step:
Divide by 32 on both sides.
x < 9.375
We can't buy 9.375 sweatshirts though, and we can't add more decimals or it will go over 300, so you round down to 9.
Dominique can buy 9 sweatshirts without going over $300!
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
Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (4, - 1)
m = 
= -
