14 pencils cost £3.36. How much would 8 pencils cost?

Answer:

Step-by-step explanation:

6x-12y

trust me

Answer:

9x-7y-3x-5y

= 6x-12y

Step-by-step explanation:

9x and -3x are like terms as they both are "x" values

-7y and -5y are like terms as they both are "y" values

To receive the x value you subtract 3x from 9x giving you 6x

To receive the y value you subtract -5y from -7y giving you -12y

Hope that helps (:

Answer:

54 1/3 yards

Step-by-step explanation:

Yards needed = Required net yards - Yards already ran

We know that Required net yards = 20

We can set yards already ran to -34 1/3

Yards needed = (20) - (-34 1/3)

= 20 + 34 1/3                   Subtracting a negative makes it a +

= 54 1/3

They have to get 54 1/3 yards on their next play to get a first down

thats the graph for the equation.

hope it helps

Answer:

x=5 and y=7

Step-by-step explanation:

The opposite parallel sides of any rhombus are going to be equal.

a.) Knowing this you take (x+14) and make it equal to (5x-2). Then you subtract the x from (x+14), and add the 2 from (5x+2), making the new equation 16=4x. You divide 4 by x and by 16, getting the final simplified answer of x=4.

b.) Using the same method you take 3y-3 and set it equal to (2y+4). Then you subtract the 2y from (2y+4) and add the 3 from (3y-3) to bother sides. Now you have your new equation and answer being y=7.

a.) x+14 = 5x-2

b.) 3y-3 = 2y+4

Answer:

There are 7456 seats on the lower level and there are 5044 seats on the middle level.

Step-by-step explanation:

Let 'X" be the number of seats on the upper level. Then we can find how many seats are on the lower level by solving the following equation...

# of seats on the lower level = 3x - 50

# of seats on the lower level = 3(2502) - 50

# of seats on the lower level = 7456

Now we just make the equation for the number of seats on the middle level, and so we get...

# of seats on the middle level = 2x + 40

# of seats on the middle level = 2(2502) + 40

# of seats on the middle level = 5044

Answer:

There are 7456 seats on the lower level and there are 5044 seats on the middle level.

Answer:

x = 9

Step-by-step explanation:

Given

(x + [tex]\frac{2}{3}[/tex] x ) - [tex]\frac{1}{3}[/tex](x + [tex]\frac{2}{3}[/tex] x ) = 10 ← distribute parenthesis

x + [tex]\frac{2}{3}[/tex] x - [tex]\frac{1}{3}[/tex] x - [tex]\frac{2}{9}[/tex] x = 10

Multiply through by 9 ( the LCM of 3 and 9 ) to clear the fractions

9x + 6x - 3x - 2x = 90

10x = 90 ( divide both sides by 10 )

x = 9

Answer: 41/50

Step-by-step explanation:

Step 1: Write down the percent divided by 100 like this:

282% = 282/100

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As 282 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(282,100) = 2. So,

(282÷2)/(100÷2) = 141/50 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 282/100 is also equal to 2 41/50 when expressed as a mixed number.

Frank's pet store

Step-by-step explanation:

Assuming they want the most fish with 12 gallons, lets see how many we can get from each place

Sally's. 12/4 = 3

3 goldfish

Franks. 12/3 = 4

4* 4 = 16.

Frank's place can get you more fish

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Find AB using the Law of Sine:

[tex] \frac{AB}{sin(C)} = \frac{AC}{sin(B)} [/tex]

Thus:

[tex] \frac{AB}{sin(40)} = \frac{47}{sin(103)} [/tex]

Multiply both sides by sin(40)

[tex] \frac{AB}{sin(40)}*sin(40) = \frac{47}{sin(103)}*sin(40) [/tex]

[tex] AB = \frac{47*Sin(40)}{sin(103)} [/tex]

AB = 31.0056916 ≈ 31.0 cm (nearest tenth)

Answers:

Graph A is a function

Graph B is not a function

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

Explanation:

To check if we have function or not, we apply the vertical line test. This test is where you ask yourself: "Is it possible to draw a single vertical line through more than one point on the curve?"

If the answer to that question is "yes it is possible", then we do not have a function. Graph B shows that we can draw a line through say x = 2 and have the vertical line intersect at points (2,2) and (2,4). The input x = 2 leads to multiple outputs y = 2 and y = 4 simultaneously. This is why graph B is not a function.

A function is only possible when any x input from the domain leads to exactly one y output in the range. Graph A is a function because we cannot draw a single vertical line to intersect through that curve more than once.

Answer:1/10

Step-by-step explanation:

Answer:

4/10

Step-by-step explanation:

Answer:

Initial population is 2,466,000 ( p0 )

Growth is 1.1% each year ( r=1.1

p(t)=p0(1+r)t

After 30 years, the population of Jamaica should be 3.42 million by that calculation, but it is only 2.95 million, so apparently that growth rate was a little high, or wasn’t sustained.

Answer:

16.8

Step-by-step explanation:

just look at the length to the side of it (the "28") and look at the given answers. 4 seems way too small and because the line is shorter than 28 it cant be 43, so 16.8 is the most reasonable option.
