Unit rate basically means by any one number so if the graph has a 1 on it then look at the number associated with 1 and thats your unit rate but if there is no 1 of something then u take any higher number and divide it by the lower number associated with it for example (look at the pic above)
Answer:
15r²-14r-8
Step-by-step explanation:
Use FOIL for this:
(5r+2)(3r-4)
First: 5r × 3r = 15r²
Outer: 5r × (-4) = -20r
Inner: 2 × 3r = 6r
Last: 2 × (-4) = -8
15r²-20r+6r-8=
15r²-14r-8
Answer:
146 ounces
Step-by-step explanation:
so we have 3 folks painting 4 walls, now each one of them works for 32 minutes
person 1............. 32 mins
person 2............. 32 mins
person 3............. 32 mins
for a total of 32+32+32 = <u>96 minutes worth of work</u>. That's for 4 walls, how many minutes worth is just 1 wall?
96 ÷ 4 = 24 mins.
so to paint a wall, it takes 24 mins of work worth.
so then, to paint 7 walls, that'd be 7 * 24 = 168 minutes worth of work.
what about for 4 folks doing it? How many times does 4 go into 168? 168 ÷ 4 = 42 mins.
