PLS GIVE THE ANSWER!!!!!! ALSO ITS NOT A NUMBER IS IT C OR A

Answer:

8

Step-by-step explanation:

Sea el número x El cuadrado será x ^ 2

Entonces la suma será; x ^ 2 + x = 72 x ^ 2 + x-72 = 0

x ^ 2 + 9x-8x-72 = 0

x (x + 9) -8 (x + 9) = 0

(x + 9) (x-8) x = 8 o -9

Como solo estamos considerando números naturales, la respuesta correcta es 8

Answer:

d is the right answer.

y is greater than x

y is equal to 4

Step-by-step explanation:

Answer:

Initially, we had:

100 grams of a mixture that is 80% seed, (or 0.8 in decimal form)

This means that the quotient between the mass of seeds and the total mass of the mixture is equal to 0.8

Then the mass of seeds, x, can be calculated as:

x/100g = 0.8

x = 0.8*100g

x = 80g

We also have another mixture, that is 5% seed (or 0.05 in decimal form)

This means that in X grams of this mixture, there will be y grams of seeds, such that:

y/X = 0.05

y = 0.05*X grams

Now, we want to create a mixture that is 40% seeds (or 0.4 in decimal form).

Let's do this.

If we add X grams of the 5% mixture, the total mass will be:

M = 100g + X.

The total mass of seeds will be:

m = 80g + X*0.05

and we want that the quotient between the mass of seeds and the total mass to be exactly 0.4

m/M = 0.4

(80g + X*0.05)/(100g + X) = 0.4

Let's solve this for X.

(80g + X*0.05) =  0.4*(100g + X)

80g + X*0.05 = 40g + X*0.4

80g - 40g = X*0.4 - X*0.05

40g = X*0.35

40g/0.35 = X = 114.2g

If we want the mixture to be exactly 40% seeds, we need to add 114.2g of the 5% mixture. (We already can see that Tom is closer to the exact result than Sally)

If we add 114g, like Tom wants, we will have:

M = 100g + 114g = 214g

m = 80g + 0.05*114g = 85.7g

m/M = 85.7g/214g = 0.4005

This is a really good aproximation, if we write this in percentage form this would be:

0.4005*100% = 40.05%

Answer:

Ricardo will have to pay $1776 at the end of the loan period.

I know this because if you multiply 12% to 1850 you get 222.

Now you multiply 222 to 8 which gives you an answer of 1776.

Hope this helps. :)

Answer:

3/10

Because there are 10 balls in all and there is one softball and two baseballs, so in total there are 3 balls that they want to try and pull. That's why it is 3/10.

Answer/Step-by-step explanation:

The equation that relates the proportional quantities would take the following form ---› [tex] y = kx [/tex], where,

y = amount of Grape juice (dependent variable)

x = amount of Apple juice (independent variable)

k = constant of proportionality (y/x)

✔️Using any of the given pair, say, (5, 8),

Constant of proportionality = [tex] k = \frac{y}{x} = \frac{8}{5} = 1.6 [/tex]

Substitute k = 1.6 in [tex] y = kx [/tex].

An equation that represents the proportional relationship would be:

[tex] y = 1.6x [/tex]

Or

[tex] y = \frac{8}{5}x [/tex]

How the equation would change if:

y = amount of Apple juice (dependent variable)

x = amount of Grape juice (independent variable)

The constant of proportionality would change, that is using a pair, say, (8, 5),

[tex] k = \frac{y}{x} = \frac{5}{8} = 0.625 [/tex]

Substitute k = 0.625 in [tex] y = kx [/tex].

The equation would now be:

[tex] y = 0.625x [/tex].

Or

[tex] y = \frac{5}{8}x [/tex]

Answer:

48.3

Step-by-step explanation:

bc =9)4

b=9

c=4       sooo 9x4=36 anddd 36+12.3=48.3. :P

Answer:

48.3 is the answer.

Step-by-step explanation:

*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^

Essentially, you are just multiplying and adding.

When it says b = 9 and c = 4, that is representing the variables. Just think of the variables as x and y (which are normally used as variables).

So, in the equation, we see that b and c are together, meaning that they need to be multiplied. When we plug in the values for those variables, we see that the equation now says:

9 * 4 + 12.3 =

Now, we just multiply 9 by 4, and add 12.3.

36 + 12.3 =

48.3

This means that the equation bc + 12.3 is equal to 48.3.

Answer:

34

Step-by-step explanation:

Subtract and divide

The amount of money company x charges than company y, in cent, for n minutes will be (20 + n) cents.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

With company x, it cost 35 cents to connect and then 5 cents for each minute.

And, With company y, it cost 15 cents to connect and the 4 cents for each minute.

Now,

Since, With company x, it cost 35 cents to connect and then 5 cents for each minute.

Hence, The cost for n minutes with company x is,

⇒ 35 + 5n

And, With company y, it cost 15 cents to connect and the 4 cents for each minute.

Hence, The cost for n minutes with company y is,

⇒ 15 + 4n

Thus, The amount of money company x charges than company y, in cent, for n minutes = 35 + 5n - (15 + 4n)

                     = 35 + 5n - 15 - 4n

                     = (20 + n) cents

Answer:

p=7

Step-by-step explanation:

Let's solve your equation step-by-step.

3+5p−12=2p+12

Step 1: Simplify both sides of the equation.

3+5p−12=2p+12

3+5p+−12=2p+12

(5p)+(3+−12)=2p+12(Combine Like Terms)

5p+−9=2p+12

5p−9=2p+12

Step 2: Subtract 2p from both sides.

5p−9−2p=2p+12−2p

3p−9=12

Step 3: Add 9 to both sides.

3p−9+9=12+9

3p=21

Step 4: Divide both sides by 3.
