Answer: 39

Step-by-step explanation:

I started with simplifying 15/5 to 3

3+9+(14 - 5)*3

Than Simplified (14 - 5) to 9

3+9+9*3

Next, I did 9*3 due to PEMDAS

3+9+27

Finally, I added it all together to get 39

What is an equation of the line that passes through the point (5, 4) and is parallel to

weqwewe [10]

Answer & Step-by-step explanation:

When two lines are parallel, their slopes are the same. To find the slope of the given equation, convert to slope-intercept form:

$y=mx+b\\\\$

m is the slope
b is the y-intercept, which is the value of y when the value of x is zero
x and y are the corresponding coordinate points (x,y)

$6x-5y=15$

Solve for y. Subtract 6x from both sides:

$6x-6x-5y=15-6x\\\\-5y=-6x+15$

Divide both sides by -5:

$\frac{-5y}{-5} =\frac{-6x}{-5} +\frac{15}{-5} \\\\y=\frac{6}{5}x-3$

The slope is $\frac{6}{5}$ .

Now you need to make an equation in point-slope form:

$y-y_{1}=m(x-x_{1})$

m is the slope
$x_{1}$ and $y_{1}$ are the coordinate points

Insert known values:

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

You can use this equation, or you can convert to slope-intercept form by solving for y:

Use the distributive property:

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

Add 4 to both sides:

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

Kate has 3 quarts of a 5% sugar solution she wants to mix this with 2478% sugar solution and X quarts of a 12% sugar solution to

jeka57 [31]

Answer:

The volume of the 12% sugar solution required, 'X' for a given volume of the 8% sugar solution, 'Y' is;

X = (2·Y + 15)/2

When the volume of the 8% sugar solution, Y = 2 quartz, the volume of the 12% sugar solution required, X = 9.5 gallons

Step-by-step explanation:

The data of the sugar solutions are;

The volume of 5% sugar solution Kate has = 3 quarts

The volume of the 12% sugar solution = X

Let 'Y' represent the volume of the 8% sugar solution, we have;

The volume of the resultant solution, Z = X + Y + 3

The concentration of the resultant solution = 10%

0.05 × 3 + 0.08·Y + 0.12·X = 0.1·(X + Y + 3)

Solving gives the relationship between the volume of the 12% sugar solution, 'X', and the 8% sugar solution, 'Y' in quartz, as follows;

X = (2·Y + 15)/2

When the volume of the 8% sugar solution, Y = 2 quartz, we have;

X = (2 × 2 + 15)/2 = 9.5

Therefore, the volume of the 12% sugar solution Katie requires to make the 10% sugar solution is 9.5 quartz.

Suppose that there are 25 students in a class, each either a freshman, a sophomore, or a junior. How many students must be in th

Yakvenalex [24]

Answer:

at least 9 students in each cohort.

Step-by-step explanation:

Given that :

In a class, there are 25 students and each of them is either a sophomore, a freshman or a junior. We have to determine the number students in the same cohort.

Let us suppose there are equal number of students in each of the cohort.

Now let us assume that the number of the students in each cohort be 8, i.e. each as a freshman, a junior or a sophomore. Therefore, the total number in the all the cohorts will be 24 students only.

Thus, we can say that there are at least $9$ freshman, at least $9$ sophomore or at least $9$ junior in each of the cohort.
