Answer: The answers are
- Subtract 7 from both sides of the equation.
- Subtract 7 from 7.
- Substitute 5 for p to check the solution.
Step-by-step explanation:
p + 7 = 12
= p + 7 - 7 = 12 - 7
= p = 5
Then for the substituting part
5 + 7 = 12
Hope this helps!
Answer:
21/9
Step-by-step explanation:
Follow PEMDAS and Order of Operations
X is 9
12x + 17 = -1 + 14x
18 = 2x
x = 9
Answer:Yes, your answers are correct.
The volume of a cone is given by V = 1/3πr²h. Since the diameter of the first cone is 4, the radius is 2; therefore the volume is
V = 1/3π(2²)(8) = 32π/3
We divide the volume of the sink, 2000π/3, by the volume of the cone:
2000π/3 ÷ 32π/3 = 2000π/3 × 3/32π = 6000π/96π = 62.5 ≈ 63.
The diameter of the second conical cup is 8, so the radius is 4. The volume then is:
V = 1/3π(4²)(8) = 128π/3
Dividing the volume of the sink, 2000π/3, by 128π/3:
2000π/3 ÷ 128π/3 = 2000π/3 × 3/128π = 6000π/384π = 15.625 ≈ 16
Step-by-step explanation:
Evaluate : 8 - 9 + (-2)
8-9= -1 (because if you take away 9 from 8, you will end up with a negative number since there isn’t enough to take away.)
-1 + -2 = -3 (this is because when you are adding two negative numbers together, you will basically just add -1 and -2 as you would normally, then you would transfer the negative sign as well to make it -3)
Finally, your answer to this question is -3.
