Answers

Answer:

Step-by-step explanation:

First you have to multiply both sides by 4

4 (3x - 1) by 4 > 3 x 4

Then simplify it:

3x-1 > 12

Now add one to both sides

3x - 1 + 1 > 12 + 1

Then simplify it again:

3x > 13

Now divide both sides by 3

3x ÷ 3 > 13 ÷ 3

Answer:

x = 13 ÷ 3

the answer is X=13/3

Draw a balanced hanger diagram for the equation 2x=4

Answers

Step-by-step explanation:

3360832553 ____ pass___ wZE2XQ

Answer:

See the attached picture.

Step-by-step explanation:

I had to look up 'balanced hanger' because that was not a term from my own math education, but I found it no problem.

See the attached picture.

There are 2 x's on the left and 4 1's on the right.

This means the equation has 2 x's on the left of the equal sign and 4 1's on the right.

Each unit of different size should be in a different shape.

The idea is that the hanger 'balances', just like a set of scales, or the same way an equation balances both sides.

Hope this helps.

A survey of students at a university shows that 4 out of 5 drink coffee. Of the students who drink coffee, 1 out of 6 adds cream to it. If the university has 18,000 students, find the number of students who drink coffee with cream.

How many students drink coffee with cream?

Answers

The number who drink coffee is 3/4 of 8000, so ...
... (3/4)×8000 = 6000.
Of those, 1/5 add cream, so the number of coffee drinkers who add cream to their coffee is ...
... (1/5)×6000 = 1200.
_____
Alternate solutions
We have computed ...
... (1/5)×((3/4)×8000) = 1200
Since multiplication is associative, you can multiply the fractions first, if you wish:
... ((1/5)×(3/4))×8000 = (3/20)×8000
... = 24000/20 = 1200
or
... = 3×(8000/20) = 3×400 = 1200

what is the rule when multiplying or dividing by a negative number to solve inequalities?

Answers

You flip the inequality.
Example: if x > -y and you divide both sides by (-1) then you flip the inequality so: -x < y

When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative YOU MUST FLIP THE INEQUALITY SIGN.

195 students went on a field trip, 21 students rode in cars and the rest of the students filled
six buses. How many students were in each bus?

Answers

Step-by-step explanation:

let x represent the bus

6x + 21 = 195

6x = 195 - 21

6x =174

x = 29

Answer:

29 students in each bus

Step-by-step explanation:

at first, 21 students rode by car. so the remaining students are 195-21=174 students.

Now if we divide the remaining number of students by the number of buses then,

[tex] \frac{174}{6} = 29[/tex]

which is 29 students in each bus.

To eliminate the x terms and solve for y in the fewest steps, by which constants should the equations be multiplied
by before adding the equations together?
First equation: 6x-5y=17
Second equation: 7x + 3y = 11
The first equation should be multiplied by 3 and the second equation by -5.
O The first equation should be multiplied by 3 and the second equation by 5.
O The first equation should be multiplied by 7 and the second equation by -6.
The first equation should be multiplied by 7 and the second equation by 6.

Answers

Based on the equation, to eliminate the x terms and solve for y in the fewest steps; the first equation should be multiplied by 3 and the second equation by 5.

Simultaneous equation

6x - 5y = 17

7x + 3y = 11

Using elimination method

Multiply equation (1) by 3 and (2) by 5

18x - 15y = 51

35x + 15y = 55

Add the equation

18x + 35x = 51 + 55

53x = 106

x = 106/53

x = 2

Substitute x = 2 into

6x - 5y = 17

6(2) - 5y = 17

12 - 5y = 17

-5y = 17 - 12

-5y = 5

y = 5/-5

y = -1

Therefore, the solution to the simultaneous equation; 6x - 5y = 17, 7x + 3y = 11 is x = 2 and y = -1

x and y are directly proportional:

This means that the equation is given by:

[tex]y = ax[/tex]

In which a is the multiplier that relates these two variables.

x= -4, y =6

We use this to find a. So
