Answer:
a = -92
Step-by-step explanation:
<u>Step 1: Subtract 29 from both sides</u>
a + 29 = -63
a + 29 - 29 = -63 - 29
<em>a = -92</em>

Answer: a = -92
Answer:
y=6
Step-by-step explanation:
y=kx
3=9k
k=3/9
k=1/3
y=kx
y=1/3 × 18
y=6
The answer would be -161z-3a
Answer:
- 32.823 kJ
- 190.4 kJ
- 260.00 kJ
- 180.012 kJ
Step-by-step explanation:
The conversion factor for food energy or thermochemical calorimetry* is ...
1 calorie = 4.184 J
1000 calorie = 4.184 kJ
__
a. 7845 cal = 7845·4.184 J = 32,823 J = 32.823 kJ
b. 4.55·10^4 cal = 4.55·10^4·4.184 J = 1.904·10^5 J = 190.4 kJ
c. 62.142 kcal = 62.142·4.184 kJ = 260.00 kJ
d. 43,024 cal = 43,024·4.184 J = 180,012 J = 180.012 kJ
_____
* The thermochemical calorie is defined in terms of the heat capacity of water. An international calorie of 4.1868 J is defined in terms of energy, without respect to the heat capacity of water.
