Answer:
The anwser is B
Step-by-step explanation:
yes, because you need to convert the repeating number into a decimal. In this case, you can assume that x is the fraction form of 0.7 repeating.
First, distribute (turning everything into a decimal at first to make more sense) : .4x - 3 + .6x = 4.25
Combine like terms : x - 3 = 4.25
Add 3 to both sides : x = 7.25
As a fraction : 7 1/4

Answer: the system of equations are
x + y = 22
x + 1.5y = 30
Step-by-step explanation:
Let x represent the number of math problems that Olivia solved.
Let y represent the number of pages that Olivia read.
Olivia completed a total of 22 math problems and pages of reading. This means that
x + y = 22- - - - - - - - - - - - - - -1
Olivia can solve each math problem in 1 minute and she can read each page in 1.5 minutes. Olivia completed a total of 22 math problems and pages of reading in 30 minutes. This means that
x + 1.5y = 30 - -- - - - - - - - - -2
Answer:
Step-by-step explanation:
Derive the equation of the parabola with a focus at (6, 2) and a directrix of y = 1. A f(x) = −1/2 (x − 6)2 + 3/2. B f(x) = 1/2 (x − 6)2 + 3/2. C f(x) = −1/2 (x + 3/2)2 + 6.
