Answer:

2 2/5

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. First convert the first into the improper fraction -8/5. Now because when dividing fractions you keep the first on, change to multiplication and flip the second equation you have

-8/5 x -3/2=?

Now you just multiply across as you would and normal time multiplying fractions. Remember a negative divided by a negative is a positive! And not after you keep, change, flip and multiply you are left with 24/10. Which is equal to 12/5 but you wanted a mixed number so we convert it into 2 2/5

Which value of p makes the equation 18+ 2 (3p – 8) = –37 true?

Volgvan

Answer:

p = -6.5

Step-by-step explanation:

Given:

18+ 2 (3p – 8) = –37

Solving for p:

18+ 2 (3p – 8) = –37
18 + 6p - 16 = -37
6p + 2 = -37
6p = -37 - 2
6p = -39
p = -39/6
p = -6.5

Answer:

36πin²

Step-by-step explanation:

Area of a circle: $A=\pi r^2$

r - radius

We are given the diameter of the circle. The radius is half the diameter.

12/2 = 6

The radius is 6cm.

$A=\pi (6)^2\\\\A=\pi 36\\\\\boxed{A=36\pi }$

The area of the circle is 36πin².
