Answer:

75-9d

Step-by-step explanation:

Hello,

The Answer to the question is 75-9d let me explain why,

you are asking, how much money is leftover. For me to get that I need to know that for every book it cost "d" dollars.

You know you have $75, and you need 9 books, we don't know how much they cost but we don't really need to.

75 - 9d

75 is the total. You need to subtract it by how many books your buying, 9.

The books are d amount of dollars, so we put 9d so that we know that for every 1 book it cost d amount so technically 9 is the amount of books times d, how much 1 book costs

Hope you can understand, I was having some trouble finding a way to explain it so my bad.

Also, I haven't done that in a while so sorry if I'm wrong

Answer:

Y=-2

Step-by-step explanation:

Hope that helps you

Answer:

y=-2

Step-by-step explanation:

first, you have to leave y alone so you have to add 2 on both sides to delete -2

y-2+2=-4+2

now -2+2=0 so that's gone and -4+2 is -2

Now you have the answer UvU

y=-2

Answer:

y = 3[tex]\sqrt{7}[/tex]

Step-by-step explanation:

The 2 right triangles inside the right triangle are similar, then ratios of corresponding sides are equal, that is

[tex]\frac{y}{9}[/tex] = [tex]\frac{7}{y}[/tex] ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = [tex]\sqrt{63}[/tex] = 3[tex]\sqrt{7}[/tex]

Answer:

17. x=11  18. x=18

Step-by-step explanation:

For 17, 14x-25=129, add 25 to 129 to get 154, then divide 154 by 14x to get x=11. The conditional for 17. would be "If J║K then alternate interior angles are congruent.

For 18. 2x-8+9x-10=180, combine like terms to get 11x - 18 =180, add 18 to 180 to get 198 than divide 198 by 11x and get x = 18. Converse statement would be, "If J║K then consecutive interior angles are supplementary.

Answer:

$365.93

$368.26

Step-by-step explanation:

The true balance :

Statement balance - outstanding cheques

Statement balance = 414.25

Outstanding cheques = 26.54 and 21.76

414.25−26.54−21.78 = 365.93

Adjusted Chequebook balance

(Hi!!) I do not know what you need in this Problem but first of all, if your looking for who typed the fastest it was Ray.

Answer:

Step-by-step explanation:

length=1 m

base of triangle=10 m

height=5m

volume= 1/2×10×5×1=25 m cube.

slant height l=√(5²+5²)=√50=5√2

slant surface area=2[5√2×1]=10√2

area of front and back=2×1/2(10×5)=50

total surface area=50+10√2≈50+14.14≈64.14 m²

It's been awhile since I've done this but I believe that's the answer, here's a picture of a pug. Smile and have a good day!

Answer:

She would need to order 11.5 pizzas. But of course she wouldn't order 11.5 so she'll just round up and order 12 pizzas.

Step-by-step explanation:

Take 4 pieces of pizza for each person and multiply that by how many people there are in this case 23. The answer would be 92 pieces of pizza would be needed to feed all of the 23 people. So you take 92 and divide it by 4 because each person gets 4 slices and the answer you get is 11.5. If the question is a multiple choice and it gives you the option of 11.5 then that's the answer but if its a fill in then round up to 12 pizzas because if not there will not be enough pizza for everyone.

Hope this helped! :)

Answer:

£ 153.93 = £154  

Step-by-step explanation:

area 1 = 15 m^2

cost= £110

cost per meter =£7.33 m^2

------------

area= 1 x b= 5 x 4.2= 21 m^2

Cost = 21 x £7.33=£ 153.93 ~ £154

I don't really know what your asking here but there we're 9 other envelopes

Answer:

Step-by-step explanation:

Store A price is 20x-7

store B price is 4(5x+7)

Where x represents the number of items.

Now, observe that the coefficient of both expressions is 20, because 4(5x+7)=20x+7

Remember that the coefficient of the x-variable is always the constant rate of change. Also, the given expressions can be expressed as linear functions

y=20x-7

y=20x+28

Observe that both Stores have already the same rate, which is  20.

Therefore, they have the same rate at any number of items dry cleaned.

What they have different is their initial condition, -7 and +7 respectively, but the rate is the same..

Answer:

Vertical angles

Step-by-step explanation:

∠[tex]5[/tex] and ∠[tex]7[/tex] are formed by the same lines and are "opposite" to each other, so they are vertical angles by definition. Hope this helps!

Answer:

f(x) = 3x² - 14x - 5

Step-by-step explanation:

multiply the factors: (x + 1/3)(x - 5)

x² - 5x + 1/3x - 5/3

x² -14/3x - 5/3

multiply by 3 to eliminate fractions:

3x² - 14x - 5

Answer:  22% of the pages are filled up

Step-by-step explanation: 900/9= 100 78% of 100 is 78

22+78=100 therefore reaching 100 percent. since 78% is empty that means 22% is being used.
