Alvin is 12 years younger than Elga. The sum of their ages is 86 what is Algas age
Ede4ka [16]

9514 1404 393

Answer:

  • Alvin: 37
  • Elga: 49

Step-by-step explanation:

Let 'a' and 'e' represent Alvin's and Elga's ages, respectively.

  a = e-12 . . . . . Alvin is 12 years younger

  a + e = 86 . . . the sum of their ages is 86

__

Substituting for 'a' gives ...

  (e -12) +e = 86

  2e = 98

  e = 49

  a = 49 -12 = 37

Alvin is 37; Elga is 49.

A cone has a volume 7065in and a height of 30 in what is the radius of the cone?use 3.14 for pi
ASHA 777 [7]

Answer:

15 inches.

Step-by-step explanation:

V = 1/3 pi r^2 h

7065 = 1/3 * 3.14 * 30 * r^2

r^2  = 7065 / (1/3 * 3.14 * 30)

r^2 = 7065 / 31.4 = 225

r = sqrt 225 = 15.

What is the answer for 1/4 ( 12x + 24 ) -9x
Gekata [30.6K]

The final expression is -6x+6

Step-by-step explanation:

The expression that we have is

\frac{1}{4}(12x+24)-9x

In order to solve the expression, we start by applying the  distributive property to the bracket. We get:

\frac{1}{4}\cdot 12x + \frac{1}{4}24 -9x

Simplifying,

3x+6-9x

Now we add the two terms in x, and we find:

(3x-9x)+6=\\-6x+6

Which is the final expression.
