Answer: 5742

================================================

Work Shown:

x = number of yes votes

(number who said yes)/(number who said no) = 4/5

x/3190 = 4/5

5x = 3190*4 .... cross multiply

5x = 12760

x = 12760/5 ... divide both sides by 5

x = 2552

There were 2552 people who voted yes

The total number of votes is 2552+3190 = 5742

What is the equation of the line in slope-intercept form?

Bingel [31]

Y= Mx+b

In the equation of a straight line,the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

Irina18 [472]

Answer:

There are 1240 students who attended Washington Middle School.

Step-by-step explanation:

Given:

Students who attend Washington Middle School are either in seventh or eighth grade.

At the end of the first semester 25% of the students at Washington Middle School were on the honor roll.

Seventh graders represented 60% of the students on the honor roll.

If 124 students on the honor roll were in eighth grade.

Now, to find the students attend Washington Middle School.

Let the total number of students be $x.$

So, the students at Washington Middle School were on the honor roll:

25% of $x$

$=\frac{25}{100} \times x$

$=\frac{25x}{100}$

$=\frac{x}{4}$

As, given seventh graders represented 60% of the students.

So, the students on the honor roll represented as seventh graders:

$60\%\ of\ \frac{x}{4}$

$=\frac{60}{100} \times \frac{x}{4}$

$=0.6\times \frac{x}{4}$

$=\frac{0.6x}{4}$

As, 124 students on the honor roll were in eighth graders.

Thus,

According to question:

$\frac{x}{4} -\frac{0.6x}{4} =124$

$\frac{x-0.6x}{4} =124$

$\frac{0.4x}{4} =124$

Multiplying both sides by 4 we get:

$0.4x=496$

Dividing both sides by 0.4 we get:

$x=1240.$

Therefore, there are 1240 students who attended Washington Middle School.

A vendor sells hot dogs, bags of potato chips, and soft drinks. A customer buys 4 hot dogs, 3 bags of potato chips, and 4 soft d

makkiz [27]

Hi, Siyasi2 ! Let x = the number of hot dogs, y = the number of chips, and z = the number of drinks. Then we know:

5x + 4y + 5z = 15.75

x = y + 0.75

z = 2x - 1

Let's substitute the 3rd equation into the first one.

5x + 4y + 5(2x - 1) = 15.75

5x + 4y+ 10x - 5 = 15.75

15x + 4y = 20.75

Now, let's re-write the 2nd equation as x - y = 0.75

We now have a system of two equations with two unknowns.

15x + 4y = 20.75

x - y = 0.75

To solve this, we can multiply the bottom equation by 4 and add.

15x + 4y = 20.75

+ 4(x - y = 0.75)

19x = 23.75

or x = 1.25

If x = 1.25, then using the one of the equations above, we can solve for y.

x - y = 1.25 - y = 0.75

.50 = y

Since z = 2x - 1, then z = 2(1.25) - 1 = 2.5 - 1 = 1.50

So, a hot dog is $1.25, chips are 50 cents, and a soft drink is $1.50. Please let me know if you have any questions.
