Answer:

-5+2

-3

Step-by-step explanation:

We start with -5 then add 2

-5+2 = -3

Step-by-step explanation:

Expression = -5 + 2

Sum = -5 + 2 = 3

Answer:

0.2

Step-by-step explanation:

5/25

= 20/100

[Multiplying by 4 to make the denominator 100]

= 0.20

[We count the number of zeroes in denominator and move the decimal to the left to the number of places same as the number of zeroes, in numerator. Here there are two zeroes after 1 (in 100, the denominator), so we moved the decimal to the left by two places (20.0 becomes 0.20)

P.S.- This works only when the denominator is something like 10, 100, 1000, 10000 etc.]

= 0.2 [0.20 is simplified as 0.2]

Or simply divide 5 by 25

A picture of the division is attached.

Steps:

1. Since 25 cannot divided 5, we will write a zero and a decimal in the quotient.

2. After this we will add a zero to 5, so that it becomes 50.

3. 50÷25 is 2, so write 2 in the quotient after the decimal.

4. Your answer is 0.2.

Answer:

THEN ITS POSITION FROM SEA LEVEL=80-25

=55

Answer:

Step-by-step explanation:

Note that

[tex]\frac{\sqrt{5}}{3}=\frac{5\sqrt{5}}{15}\\\frac{3}{5}=\frac{9}{15}[/tex]

Since

[tex](5\sqrt{5})=125 > 81 = 9^2, \text{ then }\\\frac{5\sqrt{5}}{15} >\frac{9}{15}[/tex]

So

[tex]\frac{3}{5} < \frac{\sqrt{5}}{3}[/tex]

Now clearly

[tex]\frac{\sqrt{5}}{3} < 1 < 27, 5 < 97 < 97\pi[/tex]

Therefore

[tex]\frac{3}{5} < \frac{\sqrt{5}}{3} < 27,5 < 97\pi[/tex]

Let's find the value of x,

→ 1.025x = 11.55

→ x = 11.55/1.025

→ x = 11.2682926829

→ [x = 11.27]

So, 11.27 is the solution.

Answer:

About $241.66

Step-by-step explanation:

Because the teachers sold 58 t-shirts for $12.50 each, multiply the amount of shirts sold by the price of each shirt to get the total amount of money that they made.

58 × 12.50 = 725

To find how much each teacher made, divide the total price by the number of teachers.

725 ÷ 3 = 241.66

Each teacher made about $241.66.

Step-by-step explanation:

Σfx = 60+45a

Σf = 12+9a

Now

Mean =Σfx/Σf

= 60+45a/12+9a

=105/21 (a has been canceled)

=5

Therefore mean =5

4b - 24 + 19 = 4b - (-24 + 19) = 4b - 5

The simplified expression becomes: 4b - 5

Here, we have,

To simplify the expression 4b - 24 + 19,

we can combine the like terms.

The like terms in the expression are the terms without a variable (constant terms) and the terms with the same variable raised to the same power.

Let's simplify step by step:

First, combine the constant terms -24 and 19:

-24 + 19 = -5

Now, the simplified expression becomes:

4b - 5

Answer:

-5

Step-by-step explanation:

-3y=-3x+15

y=x-5

make x=0

y=0-5

y=-5

Answer:

-x+y, +y-x is the equation of the line in slope intercept

Answer:

y= - 13x/9 + 14 2/3

Step-by-step explanation:

There are two steps to these types of questions

1. Find the slope

2. Find the y intercept

For the slope, use this formula

m = y2-y1

______

X2-x1

= - 7 - 6

______

6- (-3)

= - 13

___

9

Ok first step done, now the y intercept,

y = mx + c ( slope-intercept form)

Since now u got m, put it in

y= (-13/9)x + c

Now they gave u two different coordinates,

(-3, 6) & (6,- 7), but these two coordinates are on the same line, therefore u can choose any one of them to be your y and x

I will choose (-3, 6)

Therefore

6 = (-13/9) (6) + c

6 = - 8 2/3 + c

C = 6 + 8 2/3

C = 14 2/3

Therefore your slope intercept for will be

y= - 13x/9 + 14 2/3

Answer:

  7%

Step-by-step explanation:

Let x represent the percentage of water in the mix. The amount of water in the mix is ...

  5%·120 +10%·80 = x·(120 +80)

  14/200 = x = 7% . . . . . . . . . . . . . . simplify, divide by 200

The percentage of water in the mixture is 7%.

Carbon C diamond is one form of carbon; the other is graphite.

The correct option is A.

A chemical equation is a phrase that enumerates a compound's component elements and their respective weights. If there is just single atom of a particular sort, no subscript is necessary. If an atom contains three or more of a specific type of atom, a subscript is appended to a symbol for that atom.

here, we have,

Briefing:

Both graphite and diamond are carbon allotropes. Although graphene and fullerenes are among the rarer unusual allotropes of carbon, they do exist. An enormous three-dimensional network of carbon atoms makes up a diamond.

we know that is the importance of chemical formula :

Chemical equations provide details about the chemical composition of a compound. They also represent the proportions in which the compound's individual components come together to create the compound. The chemical formula of a compound is crucial when describing it in a chemical equation.

Answer:

I)

[tex]\displaystyle A + B + C = 2x^2 + 4xy + 2[/tex]

II)

[tex]\displaystyle A - B + C = 6x^2 -8xy[/tex]

III)

[tex]\displaystyle A + B - C= -4x^2 + 10xy -12[/tex]

Step-by-step explanation:

We are given the three equations:

[tex]\displaystyle A = x^2 + xy -6,\, B = 6xy - 2x^2 +1 \text{ and } C = 3x^2 + 7 -3xy[/tex]

I)

We want to find:

[tex]\displaystyle A + B + C[/tex]

Substitute:

[tex]\displaystyle = (x^2 + xy - 6) + (6xy -2x^2 + 1) + (3x^2 + 7 -3xy)[/tex]

Rewrite:

[tex]\displaystyle = (x^2 + 3x^2 - 2x^2) + (xy + 6xy - 3xy) + (-6 + 1 + 7)[/tex]

And combine like terms. Hence:

[tex]\displaystyle A + B + C = 2x^2 + 4xy + 2[/tex]

II)

We want to find:

[tex]\displaystyle A - B + C[/tex]

Likewise, substitute:

[tex]\displaystyle = (x^2 + xy - 6) - (6xy - 2x^2 + 1) + (3x^2 + 7 - 3xy)[/tex]

Distribute:

[tex]\displaystyle = (x^2 + xy - 6) + (-6xy +2x^2 - 1) + (3x^2 + 7 - 3xy)[/tex]

Rewrite:

[tex]\displaystyle = (x^2 + 2x^2 +3x^2) + (xy - 6xy -3xy) + (-6 -1 + 7 )[/tex]

And combine like terms. Hence:

[tex]\displaystyle A - B + C = 6x^2 -8xy[/tex]

III)

We want to find:

[tex]\displaystyle A + B - C[/tex]

Substitute:

[tex]\displaystyle = (x^2 + xy - 6) + (6xy - 2x^2 + 1) - (3x^2 + 7 - 3xy)[/tex]

Distribute:

[tex]\displaystyle = (x^2 + xy - 6) + (6xy - 2x^2 + 1) + (-3x^2 - 7 + 3xy)[/tex]

Rewrite:

[tex]\displaystyle = (x^2 - 2x^2 - 3x^2) + (xy +6xy +3xy) + (-6 +1 - 7)[/tex]

And combine like terms. Hence:

[tex]\displaystyle A + B - C= -4x^2 + 10xy -12[/tex]
