Answer:
x is 30
Step-by-step explanation:
1/2 ( x + 6 ) = 18
1/2x + 3 = 18
- 3 - 3
1/2x = 15
· 2 · 2
x = 30
The left sides of the equations are the same and the right sides of the equations are different, therefore the system of equations is inconsistent.
Answer: B. inconsistent.
Answer:
7 , 1/4
Step-by-step explanation:
Answer:
-9 + 21 = t t = 12°C.
Step-by-step explanation:
For this problem lets have t be equal to the original temperature in the beginning of the day. The equation -9 + 21 = t represents this situation because it states that if we add the degrees that dropped to the current degrees it will give us our original degrees. Solve. -9 + 21 = t (Simply add -9 + 21) -9 + 21 = (+12) 12 = t So, the original degrees in the beginning of the day was 12°C.
Original formula:
P/2-5 when p=14
You just need to plug in 14 in place of where the variable p is at. This is called substitution.
14/2-5
By the rules of PEMDAS, we will execute 14/2 first. (7)
7-5
2 is your final answer.
