Answer:
let the two number be x and y then,
x+y=12
x-y=-4
-----------
2x=8
or, x = 4 put the value of x in first equation
4+y= 12
or, y=12-4
or, y= 8 hence the two number is 4 and 8
Answer:
a. (b) 2.5
b. (b) 1.89
Step-by-step explanation:
E(X) =0(0.05)+1(0.25)+2(0.35)+3(0.15)+4(0.15)+5(0.15)= 2.5
A because, all the numbers multiplied by those factors equals their spot in the number
The equation would be 35c=x
So if C=20 then 35 x 20 = 700
So it would cost $700 to go to this yoga studio for 20 months
Hope this helps!
