Tim will buy twice as many CD's as Raul.

1 answer:

5 0

Let
$x$
represent the number of CDs Raul will buy.

Then Tim will buy , 2 times of it. That is,
$2x$

Since Tim will be waiting for Raul to buy before he doubles it, Raul has become the independent variable and Tim the dependent variable.

We can write the equation in function notation as,

$T(R)=2R$

Or

$f(x)=2x$

A van travels at a constant speed of x km/hr over a distance of 45km/hr. If the van increases its speed by 4km/h, it will be abl

harkovskaia [24]

Speed = Distance/Time. Let speed be V, distance D and time T

a)Given: D₁ =45km, V₁=x km/h
V₁=D₁/T
V₁=45/T OR T= 45/V₁

b) Given : D₂ =48 km and V₂ = V₁ + 4 km/h
V₂ = 48/T, but V₂ = V₁+4, then:

V₁+4 = 48/T OR T=48/(V₁+4). Since Time is same, then we can write:
45/V₁ =48/(V₁+4), solve for V₁:
45V₁ + 180 = 48V₁

3V₁ =180 and V₁ = x = 60 km/h
