Use a calculator, or see 34*65=2210.

Um, are you sure?

10.31=10 31/100

Why because in .31 the 1 is in the hundreths place so, its 10 31/100.

9c2–(-3c2–9c)

\(9c^2-(-3c^2-9c){\color{blue}=9c^2+3c^2+9c }\)

\({\color{blue}=12c^2+9c=3c(4c+3)}\)   !

Yes, you can.

2*.5=1

Hello!

what is 2/3x9/12

\({\color{blue}\frac{2}{3}\times \frac{9}{12} =\frac{2\times 3\times 3}{2\times 2\times 3\times 3} =\frac{3}{6}= \frac{1}{2} }\)    !

Cool! Thanks Gingerale

Groan!   Your pun gave me a tummy ache :)

It would be 1/2 or 0.5

(6/7)8 * (6/7)0 Also that "8" and the "0" is supposed to be a exponent

(6/7)^8 x (6/7)^0 = (6/7)^(8+0) =(6/7)^8.

When the base number is the same, as is the case here(6/7), you ADD the exponents, when you are multiplying them together.

7*(2^(3x-5)) = 53 divide both sides by 7

2^(3x - 5) = 7 4/7 take the log of both sides

(3x - 5) log(2) = log 7 4/7

(3x - 5) =log 7 4/7 / log (2)

(3x - 5) = 2.9205655

3x = 2.9205655 + 5

3x = 7.9205655 divide both sides by 3

x = 2.6401885

3+2w=75

we subtract 3 from both sides, then we get that

2w=72

then we divide both sides by 2 since the coefficient on w is 2, this gives us

w=36

67.75 + (-4 3/4) 

67.75 - 4.75

= 63

A pie is a baked dish which is usually made of a pastry dough casing that covers or completely contains a filling of various sweet or savouryingredients.

Pies are defined by their crusts. A filled pie (also single-crust or bottom-crust), has pastry lining the baking dish, and the filling is placed on top of the pastry but left open. A top-crust pie has the filling in the bottom of the dish and is covered with a pastry or other covering before baking. A two-crust pie has the filling completely enclosed in the pastry shell. Shortcrust pastry is a typical kind of pastry used for pie crusts, but many things can be used, including baking powder biscuits, mashed potatoes, and crumbs.

Pies can be a variety of sizes, ranging from bite-size to ones designed for multiple servings.

10.31 =10 31/100

Because y = -5 and 5x-15y must also equal -5, we can calculate:

\(5x-15(-5)=-5 \\ 5x = -80 \\ x=-16\)

So your unknown, x = -16.

The greatest common factor (GCF) of both the numbers 100 and 14 is 2; if you divide the top and bottom by two you get:

\(\frac{100}{14}\times\frac{1/2}{1/2}=\frac{50}{7}\)

So 50/7 is your most accurate answer; The decimal approximation of this number is:

\(\frac{50}{7}\approx7.143...\)

One could simplify this number to scientific form, but I'm sure that it wouldn't help;

\(1.70859375\times10^{8}\)

\(9c^2-(-3c^2-9c) \\\ \\ \text{Let's start by disbributing the negative:}\\\ \\ 9c^2+3c^2 +9c \\\ \\ \text{Now, you simply combine like terms.}\\ \text{This means, if the variable(}c\text{) has the same} \\ \text{power, then you can add those terms}\\ \text{together:}\\ \ \\ \underline{12c^2+9c} \)

You might be in reference to "pi" which is defined as the number of diameter lengths you can fit around the circumference of a circle;

 \(\pi=3.14159......\)

Pi is a transcendental number, which means that it does not have a final decimal point, and cannot be expressed by a finite fraction. There are hundreds of ways to calculate pi via formulas, but I don't think you're as interested in that.

This question is the addition of two numbers in basic algebra;

\(s=2\\ r=s+2\\ r=2+2=4\)

Rick has 4 cookies.

Yeah my bad, I made a stupid mistake. It's y = 10. -80/-8 = 10.

8(7-y)=-24

56 - 8y = - 24 subtract 56 from both sides

- 8y = - 24 - 56

- 8y = - 80 divide both sides by - 8

y = 10

Start with 0.

Simply do: 0 - 50 + 60 - 70 + 80

Which equates to 20.

Therefore, in total, there is a profit of $20.

It cannot be simplified further.
