Answer:

[tex]\frac{35}{7} =\frac{70}{14} =\frac{105}{21} =\frac{140}{28} =\frac{5}{1}[/tex]

Step-by-step explanation:

The unit rate is x:1, like 60 miles to 1 hour, or 60/1. To find the answer, put the number of textbooks over the number of students and then simplify the fractions- you will see that they all boil down to 5/1, or 5 textbooks per 1 student.

Answer:

[tex](\frac{16}{3},- \frac{1}{9} )[/tex] or [tex]x=\frac{16}{3}, y=- \frac{1}{9}[/tex]

Step-by-step explanation:

Hello again!

We are given these two systems:

4x+1=5(x-3y)-6

3(x+6y)+4=9y+19

And we want to solve them for x and y.

First, let's do the distributive property to expand out what is in the parentheses.
4x+1=5(x-3y)-6 --> 4x+1=5x-15y-6

Now simplify 4x+1=5x-15y-6

Subtract 5x from both sides

4x+1=5x-15y-6

-5x   -5x

__________

-x+1=-15y-6

Now add 15y to both sides

-x+1=-15y-6

+15y  +15y

___________

-x+15y+1=-6

Subtract 1 from both sides

-x+15y=-7

Now for 3(x+6y)+4=9y+19:

3x + 18y + 4 = 9y + 19

Subtract 9y from both sides

3x + 9y + 4 = 19

Subtract 4 from both sides

3x + 9y = 15

Here is our system now:

-x+15y=-7

3x+9y=15

On 3x+9y=15, because all of the values are multiples of 3, we can actually divide it by 3.

3x+9y=15

÷3      ÷3

x + 3y = 5

So here it is again:

-x+15y=-7

x+3y=5

These equations can actually be solved using elimination! We will be adding these equations together to clear out a variable, solve for the uncleared variable, and then use the value of the uncleared variable to find the value of the cleared variable

So, add -x+15y=-7 and x+3y=5 together.

-x+15y=-7
+

x+3y=5

_____

18y=-2

Divide both sides by 18

y=[tex]-\frac{1}{9}[/tex]

Now substitute -1/9 as y into either -x+15y=7 or x+3y=5

Taking x+3y=5 for example,

x+3(-1/9)=5

multiply

x-1/3+5

Add 1/3 to both sides

x=5+1/3=16/3

So the answer is [tex]x=\frac{16}{3} , y=-\frac{1}{9}[/tex], or as a point, [tex](\frac{16}{3},- \frac{1}{9} )[/tex]

Hope this helps!

14 > 4

14 students prefer PE

4 prefer social studies

OR

4 ÷ 20 = 0.2

0.2 = 20%

70% > 20%

70% of the students prefer PE

Answer: 5,998,000

Step-by-step explanation:

2x10^3= 2,000

6x10^6= 6,000,000

In translation, Use 1 x The Initial SIG FIGS, or first numbers. 10x10 is 100, and notice how 10 and 10 have 2 zeros, so 1x1 = 1 +00 is a way to construct the number.

In this case, the 10^x, the x can represent the number of zeros after our first value.

So, 6 + six zeros, or 6,000,000

and, 2 + 3 zeros, or 2,000

To find the difference, subtract the numbers from eachother and extract the absolute value, (meaning the final answer won't be negative).

So, 6,000,000 - 2,000 = 5,998,000, which is the answer to the prompt!

Hope this Helped!

Answer:

P(pink) = 0.225

Step-by-step explanation:

We should ignore the spinner picture because it is a trick!

We need to use the data provided in the table

We need to find the probabilty of getting pink out of all the colors:

[tex]\frac{pink}{purple\ +\ pink\ +\ yellow\ +\ blue} = \frac{9}{12\ +\ 6\ +\ 9\ +\ 13}\\ = \frac{9}{40} = 0.225\ \ (22.5\%)[/tex]

We use the probability notation:

P(pink) = 0.225

Answer: 28 inches

Step by step explaination:  

First: You do inches over feet- In/Ft

Second: you do 4/60=x/420

Next: You do 60x=1680

                       60     60

Last- Your answer is 28 inches if you divide 1680 and 60.

Did this help you?

Answer:

[tex]\huge\boxed{\sf 28\ inches}[/tex]

Step-by-step explanation:

Given that:

Height of the building = 420 feet

According to the scale,

4 inches = 60 feet

×7                ×7         [Multiplying 7 to both sides]

28 inches = 420 feet

So, Height of scale model in inches is 28 inches.

angle 4+ angle 5 = 180

40+ angle 5 = 180

angle 5 = 140

Answer:

A. 140

Step-by-step explanation:

well, one way to look at it is that ∠4 + ∠5 = 180

we are GIVEN the info that ∠4 = 40

therefore 180 - 40 - ∠5

180 - 40 = 140

Answer:Liquid assets

Step-by-step explanation: Can be valued as cash

When paying for higher education, scholarships and grants can be considered liquid assets. Hence, option A is correct.

Liquid assets are assets that can be quickly converted into cash. Although while your assets are valuable possessions that may be traded for cash, not all of them can be sold immediately away for cash or without suffering a loss. A common liquid asset is cash.

Liquid assets include cash on hand, cash stored in a bank, and possessions that can be quickly and readily converted into cash. Common liquid assets include shares, bonds, certificates of deposit, and stocks.

No, an automobile is not considered to be a liquid asset. A car is regarded as a tangible asset that depreciates over time, is more difficult to sell, and is more subject to market swings. It is also challenging to make a quick turn.

Thus, option A is correct.

Answer:

True! Since if you replace x and y with 2 and 9, you will get 9 = 2 + 7 or 9 = 2 x 2 + 5 which makes the equation true.

Answer:

Step-by-step explanation:

In the question it is given that whether ( 2 , 9 ) is solution of system of equations that are y = x + 7 and y = 2x + 5 .

And we have to tell that it is true or false.

Solution : -

As in the question we're provided with ( 2 , 9 ) . So , Here :

( 1 )

[tex] \longmapsto \qquad \:y = x + 7[/tex]

Substituting value of x and y in equation :

[tex] \longmapsto \qquad \: 9 = 2 + 7[/tex]

[tex] \longmapsto \qquad \: \boxed{\bf{9 = 9}}[/tex]

As we see that left side is equal to right side .

( 2 )

[tex] \longmapsto \qquad \: y = 2x + 5[/tex]

Substituting value of x and y in equation :

[tex] \longmapsto \qquad \: 9 = 2(2) + 5[/tex]

[tex] \longmapsto \qquad \: 9 = 4 + 5[/tex]

[tex] \longmapsto \qquad \: \boxed{ \bf{9 = 9}}[/tex]
