A. The student followed all rules correctly and solved for c
Given the equation , the student followed all rules correctly because:step 1: He combined like terms correctly for c in the left side from the equation
step 2: he subtracted 6 from both sides
step 3: To isolate “c”, he substracted 12c from both sides
Step 4: finally he divided both sides by
And he got it:
Now we´ll check this work with the original equation:
Very good √
t = 3
Compute a value for t that satisfies the equation below.
t = 3
(pretty sure for B)
It is a I took the test and i got it right.
Option A- The equations always have to be balanced.
The equation is missing in the question, so he given equation is:
C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP
The correct answer is option A.
The mass of reactant is always equal to mass of the product because the equation has to be balanced.
The reactant for cellular respiration is carbohydrates and in the presence of oxygen it is being converted into carbon dioxide and water.
The mass of reactant will always have to equal to mass of product. The energy stored in the carbohydrates is converted into adenosine tri phosphate.
so the correct option from above equation is
The student did not properly apply the addition property of equality to isolate x.
SO its B
hope it helps
For b. I would multiply the entire equation by 3 to get rid of the fraction. So the new equation is now -2t-6=-9. Isolate the variable, t, again. So it is now -2t=-3. Multiply both sides by -1/2, and t=3/2
For c. Nothing seems to be wrong except for the fact that you forgot a negative sign in one of the steps
