Answer:
C. 2y = (2x-1)/4
Step-by-step explanation:
An equation is linear when the exponents of the variables are 1 and the sum of the exponents of the variables in any term is 1.
a) 3xy = 4 . . . . sum of exponents is 1+1=2
b) f(x) = 2/3(1 -x^2) . . . . exponent is 2
c) 2y = (2x -1)/4 . . . . all exponents are 1 (linear)
d) y = 3/(x+1) ⇒ xy +y = 3 . . . . sum of exponents is 1+1 = 2
To make this easier to read, I'll be substituting 1/2 for .5; they mean the same thing, but it's less confusing to type it in its decimal form.
7x + .5 + 6x - 9.5
Combine like terms (x's can be added together, and so can reg. numbers)
(7x + 6x) + (.5 - 9.5)
13x - 9
Answer:
0.3
Step-by-step explanation
d is the feet so you would grab your calculator and do v35/4 and that would come out to (rounded to the nearest tenth) 1.4 and for the other one you would do the same thing but replace "35" with 23 and that would give you (rounded to the nearest tenth) 1.1, so what is the distance between this two? 0.3
First look to see if the largest denominator is divisible by the smaller denominator. In this case it is. So the lcd is the largest denominator 15.
Answer:
Penny needs 
cups of flour to make 3/4 of the recipe.
The recipe will make 18 cookies.
Step-by-step explanation:
We have been given that a recipe for oatmeal cookies makes 24 cookies. Penny wants to make 3/4 of the recipe.
To find the number of cookies that will 3/4 of the recipe will make, we need to find 3/4 of 24 as shown below:
Therefore, the recipe will make 18 cookies.
We are also told that recipe calls for 2 1/2 cups of flour. To find amount of flour needed for 3/4 of the recipe, we will multiply 2 1/2 cups by 3/4 as:
Therefore, Penny needs cups of flour to make 3/4 of the recipe.
