6 x 2 x 3 x 7 = 252
I am very sure
1 notebook costs $3.45
let's turn this into 2 equations, n being notebook price, and b being binder price ->
mandy -> 3n + b = 5.85
jordan -> 2n + b = 4.65
we need to take one equation, simplify for b, and plug it into the other equation, let's take jordan's equation for this ->
b = 4.65 - 2n
plug it into mandy's equation
3n + (4.65 - 2n) = 5.85
simpify until you get n = 1.20
take this and plug it back into jordan's equation ->
2(1.20) + b = 4.65
simplify until you get b = 2.25
plus this value into mnady's equation ->
3n + (2.25) = 5.85
simplify until you get that n = 2.25
Answer:
Step-by-step explanation:
so 20% of the total price equals $ 30
let x represent the total price
turn ur percent to a decimal
0.20x = 30
x = 30 / 0.20
x = 150 <=== total price
Answer:
hello your question is incomplete attached below is the missing data
answer : Y = 206.0859 - 1.3191 X
Step-by-step explanation:
Determine the regression equation using the data on revenue and distance
The regression line equation is written as :
Y = 206.0859 - 1.3191 X
applying the regression equation to data given to determine the value of Y and residual value
