Answer:

18/5

Step-by-step explanation:

From my understanding, this is 1 whole 2 upon 10

Step 1: Convert mixed fraction into fraction

Multiply whole number by denominator: 1 x 10 = 10

Add numerator: 10 + 2 = 12

Write the result as the numerator and use the same denominator.

12/10

Step 2: Find the total tape used

From my understanding, each student used 12/10 of the tap

So 3 students used: 12/10 x 3 = 18/5

Therefore, the total tape used for three students was 18/5.

1. Determine whether the lines given by the equations 2x + 3y = and y=3/2x+4

son4ous [18]

Answer:

1. Yes, the lines are perpendicular.

2. $y=\frac{5}{4}x+6$

Step-by-step explanation:

The first equation of Exercise 1 is incomplete. Let's assume that it is:

$2x + 3y =n$

Where "n" is a number.

First, it is important to remember that the equation of a line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

By definition, the slopes of perpendicular lines are negative reciprocals.

1 . If you solve for "y" from the first equation, you get:

$2x + 3y =n\\\\3y=-2x+n\\\\y=-\frac{2}{3}x+\frac{n}{3}$

You can identify that the slope is:

$m=-\frac{2}{3}$

The second equation of the line is:

$y=\frac{3}{2}x+4$

And its slope is:

$m=\frac{3}{2}$

Since the slopes are negative reciprocals, the lines are perpendicular.

2. Given the first equation of the line:

$y= -\frac{4}{5}x+6$

You can identify that:

$m=-\frac{4}{5}\\\\b=6$

Since the first line and the second one are perpendicular, you know that the slope of the other line is:

$m=\frac{5}{4}$

According to the information given in the exercise, both lines have the same y-intercept; therefore, the equation of the second line is:

$y=\frac{5}{4}x+6$

Given y=1/4x+2, i first isolate the constant. After doing so , i get the equation -1/4x+y=2.To remove the fraction, i multiply b

dexar [7]

Answer: this is wrong. The final answer should be x - 4y = 8

Step-by-step explanation:

y = 1/4x + 2

We'll first isolate the constant

-1/4x + y = 2

We remove the fraction by multiply through both sides of the equation

-4

x - 4y = 8
