Sara was thinking of a number. Sara adds 12, then divides by 7 to get an answer of 11. What was the original number?

Answer:

c.

Step-by-step explanation:

Answer:

Hey I want to try and help you out but can I know which grade you are?

Answer and Step-by-step explanation:

a - b = 2

[tex]\frac{3b}{3a}[/tex] = [tex]\frac{b}{a}[/tex]

b = a - 2

a = b + 2

______________

b = b + 2 - 2

b = b

______________

______________

a = a - 2 + 2

a = a

______________

If a equals 0, then the expression is undefined.

If b = 0, then the expression is 0.

There are infinite number of solutions when a is not 0 and the numbers are positive.

Solve the following inequality

x−3>7: x>10

Step-by-step explanation:

I did the math :)

Step-by-step explanation:

A rectangular prism is nothing but a cuboid. Let the length , width and height of the  rectangular prism be l, w and h.

We know that volume of a cuboid V = l×w×h

So,  l×w×h = 936

So, we can find any dimension of the prism provided the the other two dimensions are given to us.

Answer:

3x-2 = -x+10

or, 3x+x=10+2

or, 4x=12

or, x=12/4

So, x=3

Answer: 3

Step-by-step explanation:

Step 1: Add x to both sides.

3x−2+x=−x+10+x

4x−2=10

Step 2: Add 2 to both sides.

4x−2+2=10+2

4x=12

Step 3: Divide both sides by 4.

4x

Answer:

512

Step-by-step explanation:

You are multiplying by 4. So you’d do 128 times 4 to get 513!

Hope this helped you!

Answer:

512

Step-by-step explanation:

The sequence is going by fours

2 * 4 = 8

8 * 4 = 32

32 * 4 = 128

128 * 4 = 512

Answer:

degree of the polynomial = 7

Number of terms = 2

Name = binomial

leading coefficient = 5

Step-by-step explanation:

The polynomial is x³y² - 5x³yz³

The degree of a polynomial is the highest exponent of any of its variables.

But in this case where we have two variable together, we sum up their exponents and the Hughes one will be the degree of the polynomial.

Thus;

x³y² has a degree of 3 + 2 = 5

5x³yz³ has a degree of 3 + 1 + 3 = 7

Thus,7 is the highest and the degree of the polynomial is 7.

There are two terms which are x³y² and 5x³yz³

Since it has two terms, it is a binomial.

To get the coefficient, I will rearrange in descending order of degree;

-5x³yz³ + x³y²

Thus, leading coefficient = 5

Answer:

m = 0.75well 1.7 bc 5.35/3=1.7 This is the cost per pound of the mints.

Step-by-step explanation:

From this sentence >> 3 pounds of candy and 2 pounds of mints cost $10.80

you can make-up an equation >> 3c + 2m = 10.80 right?

That's your first equation, 3c + 2m = 10.80 ... (1)

and from this sentence >> 1 pound of candy and 3 pounds of mints cost $5.35

you can make-up an equation >> c + 3m = 5.35 ... (2)

you can use various methods here, like graphing, substitution, comparison, and elimination method.

Let's try using substitution method.

3c + 2m = 10.80 ... (1)

c + 3m = 5.35 ... (2) << here you can come up with c = 5.35 - 3m then substitute it to (1)

3c + 2m = 10.80 ... (1)

3(5.35 - 3m) + 2m = 10.80

16.05 - 9m + 2m = 10.80

-7m = -5.25

m = 0.75 <<This is the price of the mint

to get the price of candy, simply substitute m = 0.75 to (1) or (2) if you want, it depends on you.

Either way, you will have the same answer.

Let's try substituting in (1)

3c + 2m = 10.80 ... (1)

3c + 2(0.75) = 10.80

3c + 1.5 = 10.80

3c = 9.3

c = 3.1 <<this is the price of the candy

Answer: 8 : 6

Step-by-step explanation:

Answer:

-5x^6-8x^2+6x+11

Step-by-step explanation:

(-5x^6+7x+1)-(8x^2+x-10)

Remove parentheses

-5x^6+7x+1-(8x^2+x-10)

-(8x^2+x-10)=-8x^2-x+10

-5x^6+7x+1-8x^2-x+10

Simplify

-5x^6-8x^2+6x+11

Answer:

  17 2/3

Step-by-step explanation:

A calculator or spreadsheet can figure this. The maximum of f(x) is found where 3x-2 intersects 25-x.

  2x +3 = 25 -x

  3x = 22

  x = 22/3 = 7 1/3

  25 -7 1/3 = 17 2/3 . . . . maximum value of f(x)

_____

Note in the graph that the slope of f(x) decreases at about x=5. The expression with the lower positive slope is 2x+3. So, it is that expression that must equal the expression with the negative slope.

Answer:

15%

Step-by-step explanation:

plug your numbers to the equation

(85-74)/74 then multiply that by 100

then move the decimal right 2 places

Answer:

15%

First of all, you need to find the difference between 85 min and 74 min.

85-74=11 min

Now, we need to find %increase-

increase/Original *100

11/74*100=

14.8648648649

= 14.8

15% if you were to round.

The image of (-6,0) after a reflection over the line y = -x is (0,6)

Step-by-step explanation:

Here, we want to reflect the given point over the given line

Mathematically, by reflecting a point over the given line, we have the coordinates change as;

(x,y) to (-y,-x)

So, we have;

(-6,0) to (0,6)
