Answer:
65
Step by step explanation:
If 15 students drink nothing, the total of students who drink is 110-15=95.
Out of this 95, 70 drink tea and 30 drink coffee. 70+30=100 but there are only 95 students who drink so that must mean that 5 students (100-95=5) drink both. So you have to subtract five from botht the group of tea drinkers and coffee drinkers (65+5+25=95)
Answer: Crickets make 172 chirps/min at 80 degrees Fahrenheit
Step-by-step explanation:
Step 1
Using the point slope formulae for Linear functions , we have that
y - y1 = m(x - x1)
where x and y are two points representing the temperature and chirps /min respectively
And
m= slope
Step 2 : Finding the slope , m
where x1=60
y1=92
x2= 75
y2=152
m= (y2-y1)/ (x2-x1)
= (152- 92)/(75-60)
=60/15 =4
Bringing down the point/slope formula and imputing the known values to find our equation to show the relationship cricket make per minute and the temperature
y - y1 = m(x - x1)
y - 92= 4(x - 60)
y - 92 = 4x -240
y = 4x - 240 + 92
y = 4x - 148
Step 3
To find the number of chirps be per minute (y) if the temperature is 80 degrees Fahrenheit( x)
y = 4(80) - 160
y = 320 - 148
y = 172 chirps/min at 80 degrees Fahrenheit

Hi there!

I believe your answer is:
MN = 66
x = 5
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
- A midpoint separates a line segment into two congruent parts.
- Knowing that one half of the line segment, LN, measures 33, we can double it to get 66, the whole measurement of the segment.
MN = 66
⸻⸻⸻⸻
⸻⸻⸻⸻
The value of 'x' is equal to 5.
⸻⸻⸻⸻
The equation was the measurements of both sides set equal to each other.
⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
