You bought a book for $10 and 5 pens. You spent a total of $40. How much did each pen
cost?

Answers

Answer 1

Answer:

Each pen costs $6

Step-by-step explanation: $40 total -$10 from the book=$30 left.

$30 left divided by 5 pens = $6 each pen.

Answer 2

Answer: $6

Step-by-step explanation:

This is because you got a book for $10 so you would first minus 10 for the $40 you have and then you have $30 dollars left and 6 x 5 is 30 so then when you add back 10 and the 30 dollars you get the total amount of money.

How do you find ratio?

Answers

Answer:

To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2.

Answer:

Add the ratio terms to get the whole. Use this as the denominator.  Eg: 1 : 2 => 1 + 2 = 3.

Convert the ratio into fractions. Each ratio term becomes a numerator in a fraction.  Eg: 1 : 2 => 1/3, 2/3.

Therefore, in the part-to-part ratio 1 : 2, 1 is 1/3 of the whole and 2 is 2/3 of the whole.

answer for 1a: 0.40, which is 40 cents.

what you need to do is you need to divide the amount of money of the drink which is £3.20, by the quantity of the drink which is 8, since £3.20 is the total amount of money for 8 cans.
£3.20 divided by 8 is 0.4, which logically would mean in your question it calculates to 40 cents.
another proof that the answer is 40 cents is when you multiply 0.40 by 8, it calculates to 3.2, which would mean in your question it calculates to £3.20 in total.
the answer to 1a is 40 cents.


answer for 1b: 0.35, which is 35 cents.
same thing as the first question, you need to divide the total amount of money of the drink which is £5.25, by the quantity of the drink which is 15, to calculate the actual price of the drink.
5.25 divided by 15 calculates to 0.35.
as said, the proof that the answer is right is if you multiply 0.35 by 15, it will calculate to 5.25.
the answer to 1b is 35 cents.

answer for 1c: the best value is shop A, because we have worked out that shop A sells the drink for 40 cents, and shop B sells the drink for 35 cents. therefore, shop A gets 5c more profit than shop B.

Answers

It’s 20 because the only 2 multiple of 5 that lie between 18 and 30 are 20 and 25

The GCF is 2 and 25 is not divisible by whereas 20 is

Therefore the answer is 20

Hope this helps! Any questions let me know :)

The answer is 20.

Given that,

The GCF of 18, 36, and me is 2. i am a multiple of 5. i am greater than 18 and less than 30.

Based on the above information, the information is as follows:

It should be 20 because the only 2 should be multiple of 5 that lies between 18 and 30 that are 20 andn 25But the GCF is 2 and 25 should not be divisible on the other hand 20 should be divisible

Step-by-step explanation:

We  are below the line which means less than ( since the line is dotted)

We need to determine the equation for the line

The y intercept is 7 and the slope is

( 0,7) and (2,3)

m = ( 3-7)/( 2-0) = -4/2 = -2

In slope intercept form ( y=mx+b)

y = -2x+7

Changing this to an inequality

y < -2x+7

Add 2x to each side

1 tank is 2 times as much as half a tank

so u double the half tank for a whole tank

then you double the miles you can drive on a half tank to find the number of miles you can drive on a full tank

so

1/2(2)= 180(2)

2 = 360

Four typists can type a total of 600 memos in three days. At that rate, how many memos can three typists type in one day?

Answers

150 memos for 3 typists

The number of memos three typists can type in one day is given by the equation A = 150 memos

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of memos three typists can type in one day be A

Now , the equation will be

The number of typists = 4

The total number of memos by 4 typists = 600 words in 3 days

So , the number of memos by one typist for 3 days = total number of memos by 4 typists / 4

Substituting the values in the equation , we get

The number of memos by one typist for 3 days = 600/4

The number of memos by one typist for 3 days = 150 memos

So ,

The number of memos by one typist for 1 day = number of memos by one typist for 3 days / 3

Substituting the values in the equation , we get

The number of memos by one typist for 1 day = 150/3

The number of memos by one typist for 1 day = 50 memos

So ,

Number of memos three typists can type in one day A = number of memos by one typist for 1 day x 3

Substituting the values in the equation , we get

Number of memos three typists can type in one day A = 50 x 3

Number of memos three typists can type in one day A = 150 memos

Therefore , the value of A is 150 memos

Hence , the number of memos is 150 memos

Find 5 solutions for the linear equation x+5y=21 and plot the solutions as points on a coordinate plane

Answers

Answer:

(21, 0), (16, 1), (11, 2), (6, 3), (1, 4) are solutions of  [tex]x + 5\cdot y = 21[/tex]. Please see the image attached below to know the plot on the coordinate plane.

Step-by-step explanation:

Let [tex]x + 5\cdot y = 21[/tex], we can determine five distinct points by transforming this function into its explicit form. That is:

[tex]x = 21 - 5\cdot y[/tex]

Then, we evaluate the function at five distinct values of [tex]y[/tex]:

y = 0

[tex]x = 21-5\cdot (0)[/tex]

[tex]x = 21[/tex]

y = 1

[tex]x = 21-5\cdot (1)[/tex]

[tex]x = 16[/tex]

y = 2

[tex]x = 21 - 5\cdot (2)[/tex]

[tex]x = 11[/tex]

y = 3

[tex]x = 21-5\cdot (3)[/tex]

[tex]x = 6[/tex]

y = 4

[tex]x = 21-5\cdot (4)[/tex]

[tex]x = 1[/tex]

(21, 0), (16, 1), (11, 2), (6, 3), (1, 4) are solutions of  [tex]x + 5\cdot y = 21[/tex].
