Answer:
Step-by-step explanation:
<u>Given:</u>
- Total number = 700
- Off grid class = 450
- Online class = 320
- Both = 275
<u>Based on the given we find the following</u>
1) <u>Off-grid class only:</u>
3) <u>Online class only:</u>
2) <u>None of the classes:</u>
- 700 - (175 + 275 + 45) = 205

5) <u>Not off-grid:</u>
Answer:
The third one or the first one
Step-by-step explanation:
Can't be +4 or -4
Normally it is x ininput and f(x)=y
solve for y and replace y with f(x)
minus 5x from both sides
2y=10-5x
divide both sides by 2
y=5-2.5x
f(x)=5-2.5x
1 sunflower = $?
8 sunflowers = $18
Divide $18 by 8 = 2.25
1 sunflower is $2.25.
