An inequality I believe so:
p should be larger than 7.0 but less than 7.8 for a normal pH balance.
Only one answer is between 7.0 and 7.8 therefore 7.3 is the answer.
Hope this helps!
Answer:
Step-by-step explanation:
<u>As per the diagram we got:</u>
<u>As FH = 7x + 4 and EH = 9x - 2, we solve the following equation for x:</u>
- 7x + 4 = 9x - 2
- 9x - 7x = 4 + 2
- 2x = 6
- x = 3
<u>So each segment is:</u>
<u>Therefore</u>:
<u>So the variables are:</u>
Answer
C = -1
Step-by-step explanation:
substitute
6(3)-2(3-c)=10
18-6+2c=10
12+2c=10
12-12+2c=10-12
2c=-2
c=-1
