-2(p - 1) = 15 helllp plss slol

Answers

Answer 1

Answer:

-13/2

Step-by-step explanation:

Answer 2

Answer:

P = -6.5

Step-by-step explanation:

Multiply -2 x p and -2 x -1

The equation now is -2p + 2 = 15

Subtract the 2 to both sides to cancel it out

The equation now is -2p = 13

Divided both sides by -2 to isolate the p variable

p = -6.5

You can check your answer by subtracting -6.5 by -1 (which equals -7.5)

And then multiply -7.5 by -2 which equals 15

Is the point (10,-2) a solution to the equation y = -2x + 16? Explain,
??? pls answer

Answers

Answer:

no

Step-by-step explanation:

y = -2x + 16

-2 = -2(10) + 16

-2 = -20 + 16

-2 = -4

which is wrong

Plug the point (10,-2) into y = -2x + 16 and solve. If the equation is a true, then yes, it is a point on the equation.

y = -2x + 16 > -2 = -2(10) + 16

Now, solve.

-2 = -2(10) + 16 > -2 = -20 + 16  - Start by multiplying out parenthesis.

-2 = -20 + 16 > -2 = -4 - Add.

-2 = -4

The equation cannot be simplified any further. Since -2 is not equal to -4, we can conclude that no, (10,-2) is not a solution to the equation y = -2x + 16.

The answer is 10

Answers

Answer:

x = 10

Step-by-step explanation:

Since ΔCDE ~ ΔQRS, we can find the actual length of x + 8 first before finding the value of x.

Length of x + 8 = [tex]\frac{12}{20}[/tex] × 30

                         = 18

x + 8 = 18

x = 18 - 8

x = 10
