Answer:
C. 300=60+30w
Step-by-step explanation:
Given:
Price of television-$300
Initial Payment-$60
Weekly payments-$30
Let weekly payments be w:
The initial payment plus the weekly installments should be equivalent to the television price:
The number of weekly payments is 8 weeks and the equation to solve for w is
300=60+30w
Answer: Choice A. (8, 4)
==========================================================
Explanation:
Because x = 2y, we can replace every copy of x with 2y
Let's do so in the second equation
3x - 4y = 8
3(x) - 4y = 8
3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y
6y - 4y = 8
2y = 8
y = 8/2 ..... divide both sides by 2
y = 4
Use this y value to find x
x = 2y
x = 2*4
x = 8
So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.
Answer:
Describe in detail how you would create a number line with the following points: 3, 2.25, the opposite of 4, and – (–1fraction of one-half). Please be sure to describe on which tick marks each point is plotted and how many tick marks are between each integer. It may help for you to draw this number line by hand on a sheet of paper first.

Answer: 1809.56
Step-by-step explanation: Find The Radius Of A Quarter (Half Of The Diameter) Then Square The Radius, Or Multiply It By Itself. Then, Multiply The Squared Radius By Pi, Or 3.14, To Get The Area.
The figure below shows the standard normal distribution or "bell-shaped" curve, plotted against the z-score.
The z-score is defined as
z = (x - μ)/σ
where
x = nrandom variable
μ = mean
σ = standard deviation.
As z-values decrease, areas to the left of z decrease as shown by the shaded area.
Answer:
Areas to the left of z decrease.
