Answer:
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour
Step-by-step explanation:
Ex: If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
120/3 = 40/1
The unit rate of 120 students for every 3 buses is 40 students per bus. You could also find the unit rate by dividing the first term of the ratio by the second term.
Answer:
Step-by-step explanation:
19) 340-76= 264 ft
20) -320+23 = -297 F
21) 50-85-12+93 = 46 points
22) 26-5-2+1-6 = 14$
23) -3 + 18 = 15 F

Hike 3: Final elevation = 62 + -100 = -38.
Answer:
y = x - 6
Step-by-step explanation:
the slope-intercept form for any line is y = mx + b, where m is the slope and b is the y-intercept.
now, let's calculate the slope:
1-2/7-8= -1/-1 = 1
here is the equation we currently have solved: y = x + b
now we have to solve for the y-intercept. to do this, we substitute one of the given points into the equation, and solve for b.
let's use (8, 2). in this ordered pair, the 8 is the x, and the 2 is the y.
2= 8 +b
2 -8=b
b=-6
and now we have our final equation!
y = x - 6
