[tex]x = 10.6[/tex]

Step-by-step explanation:

[tex] \sin( {62}^{o} ) = \frac{x}{12 } \\ x = 12 \sin( {62}^{o} ) \\ x = 10.6[/tex]

Answer:

x = -4

Step-by-step explanation:

x + 4 = -x - 4

adding both side with x

x + x + 4 = x - x - 4

2x + 4 = -4

give both side (-4)

2x + 4 - 4 = -4 - 4

2x = -8

x = -8/2 = -4

Answer:

m=12

Step-by-step explanation:

it is right

Answer:

m = 12

Step-by-step explanation:

8(m – 5) = 2(3m - 8)

Distribute the 8 to (m-5) and the 2 to the (3m-8)

8m-40=6m-16

Add 40

8m=6m+24

Subtract 6m

2m=24

Divide 2

m=12

Answer:

length is between 1 inch and 2 inches

Step-by-step explanation:

Given that :

Length of Mp3 = 1 3/4 inches

Converting to decimal :

7/4 inches = 1.75 inches

1.75 lies in between 1 inch and 2 inches ;

1.75 > 1 and 1.75 < 2

Hence,

1 < 1.75 < 2

Hence, length is between 1 inch and 2 inches

  A  y = 2x + 5

Step-by-step explanation:

The cost per dog is the slope of the cost equation, 2. The equation can be written in point-slope form as ...

  y -7 = 2(x -1) . . . . using the point (1, 7)

Simplified, this is ...

  y = 2x -2 +7

  y = 2x +5 . . . . matches choice A

Step-by-step explanation:

20%=cows 0.4(40%)=goat 40%=sheep

if 40%sheep=40 sheeps

20% cow=x

20%×40=40%×x

8=40%x

x=8/40%

x=20

..so there are 20 cows

sorry...not sure

Answer:

There are 20cows

Step-by-step explanation:

20%=0.2 of cows

0.4=goats

1-(0.2+0.4)=0.4 are sheep

Using ratio and proportion,

0.2/0.4×40=20

Answer:

The cost when the two companies charge the same is $7,703.

Step-by-step explanation:

Let 'x' represent the number of tons.

For x tons the first company will charge:

5297 + 200.50x

For x tons the second company will charge:

6500 + 100.25x

We want to find x so that both companies charge the same, that is:

5297 + 200.50x = 6500 + 100.25x

x = 12 tons

For 12 tons both companies will charge the same.

The cost charged for 12 tones is:

5297 + 200.50*12 = $7,703

Hope this Helps! :)

Step-by-step explanation:

Given

a = - 3

for a)

= 2* (-3)

= -6

for b)

= (-3)²

= 9

for c)

= 3 * (-3)²

= 3 * 9

= 27

Step-by-step explanation:

Here, we want to fill out the properties of the given expression

1. Polynomial

Yes, it is a polynomial as it satisfies the properties

2. Degree

The degree is the highest power

we have a raiders to 2 and b raised to 1 giving the total power as 3

3. It has just two terms

4. It is a monomial

Answer:

[tex] \frac{3}{4} = \frac{12}{x} \\ 3x = (12 \times 4) \\ x = \frac{(12 \times 4)}{3} \\ x = (4 \times 4) \\ x = 16[/tex]

Answer:

x = 16

Step-by-step explanation:

so 3/4 = 12/x

you Can multiply 3/4 by 4 to get

12/16 = 12 / x

you can assume x = 16 since the numerators are the same

Answer:

1: The car is moving at a constant speed

2: The car is stopped

3: The car is decreasing in speed

Step-by-step explanation:

1. It's moving at a constant speed as it's moving up in a straight line

2. It's stopped because the line is flat

3. It's slowing down as the slope is getting smaller

Determine the opposite of the point

Represent the point with x; we have to first, determine point x

From the number line:

[tex]x = -2.5[/tex]

The opposite of number x is -x

[tex]-x = -(-2.5)[/tex]

[tex]-x = 2.5[/tex]

Hence, the opposite of the point is 2.5

Answer:

The solution to the equation is as follows;

[tex]x = \frac{5}{19} ,\ and \ y= \frac{2}{19}[/tex]

Step-by-step explanation:

Given;

5x - 3y = 1

3x + 2y = 1

Solving both equation simultaneously;

2:   10x  - 6y = 2

3:   9x   + 6y = 3

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

        19x   + 0 = 5

            x = 5/19

substitute the value of x in any of the equations above and solve for y;

5x - 3y = 1

5 (5/19) - 3y = 1

25/19 -3y = 1

[tex]3y = \frac{25}{19} -1\\\\3y = \frac{25-19}{19} \\\\3y = \frac{6}{19} \\\\y = \frac{2}{19}[/tex]

Step-by-step explanation:

On each side of this quadrilateral, you have supplementary angles, in other wourds, angles that sum up to one hundred eighty degrees:

[tex]\displaystyle 180° = [3y + 14]° + [10y - 29]° \\ 180° = [-15 + 13y]° \\ \frac{195}{13} = \frac{13y}{13} \\ \\ 15 = y; 59° = [3(15) + 14]° \\ \\ \\ \\ 180° = [5x - 2]° + [x + 14]° \\ 180° = [12 + 6x]° \\ \frac{168}{6} = \frac{6x}{6} \\ \\ 28 = x; 138° = [5(28) - 2]°[/tex]

Answer:

-5=5x+5y when you divide it by 5 I don't understand how the equation then becomes x=-1-y when you are dividing by a positive 5

Step-by-step explanation:

Example Question #1. If 7x + y = 25 and 6x + y = 23, what is the value of x? You could also solve one equation for y and substitute that value in for y in the other equation: 6x + y = 23 → y = 23 – 6x.

The amount of money Brooklyn need to invest, for the value of the account to reach $530 in 7 years is $500

An equation is an expression that shows the relationship between two or more numbers and variables.

Let P represent the amount of money that Brooklyn should invest, hence:

Since the interest is 1.9% (0.019) in 7 years, therefore:

[tex]$530=P(1 + \frac{0.019}{1} )^{1*7}\\\\\\[/tex]

[tex]P=464.58[/tex]

Answer:

f your number is x, then the difference between that number and 8 would be x-8. Twice that is 2(x-8)

Three times the sum of the number and 3 would be 3(x+3). So, you get the equation:
