Answer:
x=3 and y=2
Step-by-step explanation:
1.) 4x+3(5x-13)=18
expand into 4x+15x-39=18
18+39= 57
15x+4x= 19x
57/19= 3 so x=3
substitute 3 into y= 5x - 13
and you get 2 so y=2
We can do like we did before, distribute the denominator,
Answer:
1. The second number line, the third number line, the first number line.
2.
First, convert 5 hours into minutes:
5 hours 60 min
------------ * --------------- = 300 min
1 1 hr
Next, find the unit rate in m/min:
9673.6 m
--------------- = 32.24 m/min
300 min
Now find the distance you can walk in 70 minutes at this rate:
32.24 m
------------- * 70 min = 2247 meters (answer)
1 min
You could walk 2247 meters (to the nearest meter) in 70 minutes.
Answer:
-4/151
Step-by-step explanation:
We can find the slope by
m = (y2-y1)/*x2-x1)
= (3.6 - 4.8)/(2.65 - -42.65)
= (3.6 - 4.8)/(2.65 +42.65)
= -1.2 / 45.3
-4/151
