Answer:
8 = m, No solution
Step-by-step explanation:
1. -88 = -3(4m + 5) - (1 - 3m)
-88 = -12m - 15 - 1 + 3m : distributed into parentheses
-88 = -9m - 16 : combined like terms
+16 + 16 : adding to cancel out
-72 = -9m
/-9 /-9 : dividing by -9 to cancel
8 = m
2. -4(5k - 7) + 2k = -2(9k + 5)
-20k + 28 + 2k = -18k - 10 : distributed into parentheses
-18k + 28 = -18k - 10 : combined like terms
+ 10 + 10 : adding to cancel out
-18k + 38 = -18k
+18k +18k : adding to cancel out
38 = 0k (No solution)
182.5 + 50 = 232.5. 267.5 was spent
Answer:
(-4,-5)
Step-by-step explanation:
The slope of the line passing through (3,5) and (-2,1) would be:
It would be:
y2 - y1 / 2 and x2 - x1 / 2
= 1 -5 / 2 and -2 -3 /2
= -4/2 and -5/2
= (-4,-5)

Answer:
<em>The approximate probability that a random vehicle is a passenger car is 74.67%</em>
Step-by-step explanation:
<u>Probability</u>
The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.
We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:
p = 0.7467
p = 74.67%
The approximate probability that a random vehicle is a passenger car is 74.67%
