Malcolm and Ravi raced each other. The average of their maximum speeds was 260\text{ km/h}260 km/h260, space, k, m, slash, h. If

nikdorinn [45]

Let m and r represent the maximum speeds of Malcolm and Ravi in km/h, respectively.

... (m + r)/2 = 260 . . . . . the average of their speeds was 260 kph

... 2m = r + 80 . . . . . . . . double Malcolm's speed is 80 kph more than Ravi's

The second equation can be solved for r and that expression substituted into the first equation.

... 2m - 80 = r . . . . . . . . . . . an expression for r from the second equation

... (m + 2m - 80)/2 = 260 . . . the result of substituting that into the first

... 3m - 80 = 520 . . . . . . . . multiply by 2

... m = 200 . . . . . . . . . . . . . add 80 and divide by 3

... 2·200 - 80 = r = 320 . . .substitute the value of m into the expression for r

Malcolm's maximum speed was 200 km/h.

Ravi's maximum speed was 320 km/h.

Answer:

The area of the rectangle is $A=12b^6+6b^3-18b^2$

Step-by-step explanation:

Area of a rectangle

A rectangle of height H and width W has an area of:

$A=H*W$

The rectangle shown in the figure has a height of:

$H=3b^2$

And a width of

$W=4b^4+2b-6$

The area is

$A=(3b^2)(4b^4+2b-6)$

Operating:

$A=(3b^2)*4b^4+(3b^2)*2b-(3b^2)6$

$A=12b^6+6b^3-18b^2$

The area of the rectangle is $A=12b^6+6b^3-18b^2$

Wilma earns $9 per hour at her job. Then she spent $15 on a birthday gift for her best friend. Write an expression to represent

frozen [14]

Answer:

Wilma has $12.

Step-by-step explanation:

Since we don't know how many hours she worked, we know that Wilma earned 9x dollars at her job. Then she spends $15, so we can just subtract 15 from 9x.

$9x-15$
