Answer:
student 1
Step-by-step explanation:
48x+56=8(6x+7)
To draw a histogram, you need two axes. The horizontal axis is the day and the vertical axis is the number of text messages. For the first day, there are 20 text messages. This is represented by a bar starting from the horizontal axis labeled Day 1 going up to the point where the vertical axis indicates 20 text messages. This is done for the rest of the data. Afterwards, a line is drawn from the vertex of the axes connected to the top of the first bar. Then from the top of the first bar, a line connects it to the top of the next bar. This is done for all the bars before producing a histogram.
Alrighty, let's think of it like this: You are trying to fill a box with a bunch of sports balls. You have tiny little golf balls, and you have giant bowling balls. You need to fill this same box all the way up.
If you fill it with the tiny golf balls, you are going to need a <em>whole lot of them!</em>
If you are putting in bowling balls, only a few of them will fit, because they are so much bigger.
When it comes to your fraction, the box is the the number 8/10. That number will not change because we are not changing the size of the box.
We are just changing what we are filling it with. Manny, can fit 8 parts, or in this case balls, into the box.
It says Ana uses fewer parts, so she cannot fit as many in as Manny.
This means that Manny would have the golf balls, since he can fit more in than Ana, who must have the bowling balls.
So which is bigger? A bowling ball or a golf ball?
A bowling ball, which is what Ana has. So <u><em>Ana's part will be bigger</em></u> in size.
x = 6 ± √30
x² + 2( -6)x + 36 = - 6 + 36
(x - 6)² = 30 ( take the square root of both sides )
x - 6 = ± √30 ( note plus or minus )
add 6 to both sides
x = 6 ± √30 ( exact solutions )
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
