(Solving for a). b=(4*a)-3/4

Answers

Answer 1

Answer:

a = 3/28

Step-by-step explanation:

To start solving for a variable, you need to isolate it.

-4/3b = 4a

-4/3 divided by 4 equals -4/12 or -1/3

a = -1/3b

To completely solve for a we need to plug it back in and solve for b.

b = (4(-1/3b)) - 3/4

b = -4/3b - 3/4

7/3b = -3/4

b = -9/28

Finally, we can plug b back in to the previous equation we got for a to solve for a.

a = -1/3(-9/28)

a = 3/28

Furthermore, we can check if this is correct by plugging in 3/28 for a into the original problem and see if we get what we got for b (-9/28)

Answers

Answer

392in³

Step-by-step explanation:

Volume=base X height divided by 3 OR length X width X height divided by 3

length=8in

width=7in

height=21in

So, Volume = 8x7x21

1,176in³

Now divide by 392in³

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.

Answers

Answer:

The relation is [tex]y = -1.5x[/tex]

Step-by-step explanation:

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

[tex]y = ax[/tex]

[tex]6 = -4a[/tex]

[tex]a = -frac{6}{4}[/tex]

[tex]a = -1.5[/tex]

The relation is [tex]y = -1.5x[/tex]

Answers

Answer:

domain: all natural numbers greater than zero and less than or equal to 21

You cannot go for zero nights, and the maximum number of nights you can stay is 21. You also cannot have fractional night, so your answer has to be in natural numbers.

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

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.

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.

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

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
