For twice a number we can use the variable x
For four times a number we can use the variable c

4c - 2x + 15

I believe this is correct although I'm not 100% sure

Steps on how to Solve 7 - 2p > -5

ale4655 [162]

Hello!

Answer:

p<6

*The answer must have a positive sign and less than symbol sign.

Step-by-step explanation:

First, you subtract by 7 from both sides of an equation.

$7-2p-7>-5-7$

Then, simplify.

$-2p>-12$

Next, multiply by -1 from both sides of an equation.

$(-2p)(-1)$

Simplify.

$2p$

You can also divide by 2 from both sides of an equation.

$\frac{2p}{2}$

And finally, simplify and solve. You can also divide by the numbers.

$12/2=6$

Final answer: $p$

Hope this helps!

Thanks!

Have a great day!

A stone is thrown at an angle of 30° above the horizontal from the top edge of a cliff with an initial speed of 12 m/s. a stop w

stellarik [79]

To solve this problem you must apply the proccedure shown below:
1. You must apply the following formula:
yo=-(Voy)t+gt²/2
2. You have that:
Voy=VoxSin(30°)
Voy=(12 m/s)(Sin(30°))
Voy=6 m/s
t=5.6 s
g=9.8 m/s²
2. When you susbtitute these values into the formula, you obtain:
yo=-(6 m/s)(5.6 s)+(9.8 m/s^2)(5.6 s)²/2
yo=120.06 m
Therefore, the answer is: 120.06 m
