1200/8 = 150 thus, 150 per calorie. 150 x 3 = 450 :)
<u>Answer:</u>
2(-5 - 7j) = -10 - 14j
<u>Step-by-step explanation:</u>
Using the distributive property means that we have to multiply both -5 and -7j by 2:
2(-5 - 7j)
⇒ 2 × -5 + 2 × -7j
⇒ -10 - 14j
Add 7 on both sides to then left side cancels out and you end up with 13x=143 then you divide 13 on both sides and get x=11
X = 15
y = 21
First, solve for x on the right side triangle by adding angles and equaling to 180.
Now since you know the x value, solve the middle angle for the left side triangle. Add all angle on left triangle and equal them to 180.

Answer:
Option C. x=-3
Step-by-step explanation:
we have
----> inequality A
solve for x
subtract 60 both sides
![-15x\leq 105-60](https://tex.z-dn.net/?f=-15x%5Cleq%20105-60)
![-15x\leq 45](https://tex.z-dn.net/?f=-15x%5Cleq%2045)
Divide by -15 both sides
Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
![x\geq -3](https://tex.z-dn.net/?f=x%5Cgeq%20-3)
The solution of the inequality A is the interval [-3,∞)
we have
----> inequality B
Solve for x
subtract 11 both sides
![14x\leq -31-11](https://tex.z-dn.net/?f=14x%5Cleq%20-31-11)
![14x\leq -42](https://tex.z-dn.net/?f=14x%5Cleq%20-42)
Divide by 14 both sides
![x\leq -3](https://tex.z-dn.net/?f=x%5Cleq%20-3)
The solution of the inequality B is the interval (-∞,-3]
The solution of the system is
(-∞,-3] ∩ [-3,∞) =-3
therefore
The solution is x=-3
