Answer: Hi, first lets give our variables some names.
Lets call Ks to Karen's salary and Js to Jason's salary.
then, in 1995:
Ks₁ - Js₁ = 2000$
in 1998:
Ks₂ - Js₂ = 2440$
now, we know that Ks₂ = (1 +p)*Ks₁ and Js₂ = (1+p)*Js₁
so we can write the second equation as:
p*(Ks₁ - Js₁ ) = 2440$
replacing the parentesis with the first equiation
(1+p)*(2000$) = 2440$
(1+p)= 2440/2000 = 1.22
so p = 0.22, or a 22%
Company A is cheaper by
Company A costs $0.11 per minute.
Company B costs $0.13 per minute.
To find out how much a company charges per minute, for example, company A, take $132 and divide it by 1200, which gives you $0.11.
The value of x is 30; hence 4x is equal to 120. That is because the sum of the angles of a triangle is 180. So, add x, x and 4x together, you get 6x. Divide 180 by 6, you get 30. Hope this helped!
Answer:
Since the slope of the line is (31/4 - 25/4) / (5/4 - 3/4) = 3 that means that for every 1 that x increases, y increases by 3 so an example could be 1 3/4 for x and 9 1/4 for y.
