x - 6 = - 4

Answer: x = 2

x + 3 = -7

Answer: x = -10

5x = -2

Answer: x = -0.4

0.5x = 5

Answer: x = 10

The solutions to the equations as arranged are 2, -10, -0.4 and 10 respectively

Given the following equations

x − 6 = -4

Add 6 to both sides

x - 6 + 6 = -4 + 6

x = -4 + 6

x = 2

For the equation x + 3 = -7

Subtract 3 from both sides

x + 3 -3 = -7 - 3

x = -10

For the equation 5x = -2

x = -2/5

x = -0.4

For the equation

0.5x = 5

x = 5/0.5

x =10

Hence the solutions to the equations as arranged are 2, -10, -0.4 and 10 respectively

Answer:

Hello! :) have a good day!

2x + 12

Answer:

First: Multiply the numbers

2 x 10 + 2 (x -4)

20+2(x-4)

Secondly: Distribute

20+2(x-4)=

20 + 2x - 8

Thirdly: Subtract the numbers

20 + 2x - 8=

12 + 2x

Lastly: Rearrange terms

12 + 2x

2x + 12

And that would leave us with our answer 2x + 12!

Answer: The probability of rolling a 2 on a 6-sided die is 1/6.

Step-by-step explanation:

The probability of getting 2 on the die P(2) is 1/6.

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, We roll a six-sided die,

So, Sample space N(S) = 1, 2, 3, 4, 5, 6 = 6.

N(2) = 1

∴ The probability of getting the number 2 when we throw a die is

P(2) = N(2)/N(S).

P(2) = 1/6.

Answer:

y = 2x - 10

Step-by-step explanation:

Slope-intercept form is...

y = mx + b

To get the slope, you have to use the formula...

(y2 - y1) / (x2 - x1)

In this case,

y2 = 2

y1 = 10

x2 = 6

x1 = 10

So...

(2 - 10) / (6 - 10)

= -8 / -4 = 2

Therefore, slope is 2

y = 2x + b

Using any of the two x and y value provided, input the values in the equation

(I'm going to use 6,2)

2 = 2(6) + b

2 = 12 + b

b = -12 + 2

b = -10

Put this all together...

y = 2x - 10

Answer:

cost of 1 tie = 11

cost of 1 shirt = 52

Step-by-step explanation:

Answer:

the third one!

Step-by-step explanation:

Because it says, the SUM of the number, x (or z I can't really see it well) and 1/2, you must add those two together:

1/2 + x

Then it says those two numbers equal to 4, so it would look like this:

1/2 + x = 4

Because you are trying to isolate, and solve for x, you must SUBTRACT 1/2 from both sides of the equal sign:

1/2  +  x  =  4

-1/2            -1/2

1/2 minus 1/2 would result 0, so there would be x by itself. and 4 minus 1/2 would be 3 and a half ( 3  1/2), so x would be  3  1/2

x = 3 1/2

Hope this helped. If this is incorrect please specify so I can help :)

Step-by-step explanation:

The answer should be 18 centimeters

If i am wrong I am sorry

The third leg of the right-angle triangle will be 12 cm.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

The hypotenuse of the right-angle triangle is 13 cm and the perpendicular of the right-angle triangle is 5 cm.

Then the measure of the third side (B) of the right-angle triangle will be

13² = 5² + B²

169 = 25 + B²

 B² = 169 - 25

 B² = 144

   B = 12

Thus, the third leg of the right-angle triangle will be 12 cm.

The loss percentage is 20%.

We have the following information available from the question is:

Saggar sold a watch at Rs.400 that he had purchased at Rs.500.

We have to find the Percentage loss.

Now, According to the question:

Cost price of watch is (CP): $500

Selling price of watch is (SP): $400

Loss percentage= Loss/CP x 100.

Loss = C.P. - S.P.

Loss = 500 - 400

Loss = $100

Plug all the values in the formula of loss percentage.

Loss percentage = 100/500 x 100

Loss Percentage is 20%

Answer:

The equation of a line parallel to y = x - 3 that contains the point (-2, 1) is:

The graph of both the parallel equation is shown below to make you further understand the concept.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given the equation

[tex]y = x - 3[/tex]

comparing with the slope-intercept form of the line equation

Slope m = 1

Important Tip:

Thus, the slope of the parallel line is also 1.

As the parallel line contains the point (-2, 1).

so substitute m = 1 and (-2, 1) in the slope-intercept form of the line equation to determine the y-intercept of the parallel line

[tex]y = mx+b[/tex]

[tex]1 = 1(-2) + b[/tex]        ∵ (x, y) = (-2, 1) and m = 1

[tex]1 = -2 + b[/tex]

switch sides

[tex]-2+b = 1[/tex]

add 2 to both sides

[tex]-2 + b + 2 = 1 + 2[/tex]

simplify

[tex]b = 3[/tex]

Thus, the y-intercept b of the parallel line is:  b = 3

now substitute b = 3 and m = 1 in the slope-intercept form of the line equation to determine the  equation of the parallel line

[tex]y = mx + b[/tex]

[tex]y = (1)x + 3[/tex]

[tex]y = x + 3[/tex]

Therefore, the equation of a line parallel to y = x - 3 that contains the point (-2, 1) is:

The graph of both the parallel equation is shown below to make you further understand the concept.

From the graph:

It is clear that both lines are parallel.
