Answer:
34/95
Step-by-step explanation:
Since 38 students choose football and 23 students chose tennis, then 95 - 38 - 23 = 34 students chose running. The probability is 34 / 95.
Answer:
2 acres/hour
Step-by-step explanation:
Please share the possible answer choices. Thank you.
If two points on this straight line graph are (3, 1.5) and (5, 2.5), then we can find the slope of this line as follows:
As we move right from x = 3 to x = 5, x (the "run") increases by 2 and y (the "rise") increases by 1. Thus, the slope of this line is m = rise / run = 2/1, or
m = 2.
area mowed
The units of measurement here are m = ----------------------
time spent
and so we could conclude that the rate is 2 acres per hour.
Isolate the variable, note the equal sign, what you do to one side, you do to the other.
1) 4k = 24
Isolate the variable, k. Divide 4 from both sides of the equation:
(4k)/4 = (24)/4
k = 24/4
k = 6
2) 34 + h = 60
Isolate the variable, h. Subtract 34 from both sides of the equation:
34 (-34) + h = 60 (-34)
h = 60 - 34
h = 26
3) 1/5x = 30
Isolate the variable, x. Multiply 5 to both sides of the equation:
(5) * (1/5)x = (30) * (5)
x = 30 * 5
x = 150
4) m - 42 = 85
Isolate the variable, m. Add 42 to both sides of the equation:
m- 42 (+42) = 85 (+42)
m = 85 + 42
m = 127

Answer: 1:2
Step-by-step explanation:
BC= 6m
RS= 12m
BC/RS = 6/12
in simplest form 1/2
Answer:
(2, 3) lies on the line y = 5 - x.
Step-by-step explanation:
Were there only two possible answer choices?
We can determine whether or not a given point, such as (2, 3), is contained in a function such as y = x - 1, by substituting the given coordinates 2 and 3 for x and y respectively; is the resulting equation true or false?
Check out (2, 3) and y = x - 1: 3 = 2 - 1, or 3 = 1. False. (2, 3) does not lie on the line y = x - 1. Does (2, 3) lie on the line y = 5 - x? Is 3 = 5 - 2 true? Yes. So (2, 3) lies on the line y = 5 - x.
Check out (2, 3) and y = 7 - 2x. Is 3 = 7 - 2(1) true? No, it is not true.
