Answer:113

Step-by-step explanation:

I’m not really sure but the exterior angle lies on a straight line meaning that it has to amount to 180 degrees. 67 + x =180 so x = 180-67 which is 113. But I’m not entirely sure bout this.

Step-by-step explanation:

67-180=113

x=113

and the third corner =15 degrees

Answer: 10.5 feet

Step-by-step explanation:

From the question, we are informed that Marcel is purchasing a board to build a bookcase he wants to divide the board into 1.75-foot sections and that he needs 6 sections.

The size of the board that Marcel need will be calculated by multiplying 6 by 1.75 foot. This will be:

= 6 × 1.75

= 10.5 feet

The value of x = 1/2 , y = 3 of the simultaneous equation.

"Simultaneous Equation is an essential Chapter in the Algebra branch of Mathematics. There are times when you come across two or more unknown quantities and two or more equations relating to them. These are called Simultaneous Equations. When you are asked to solve such equations, you must find values of the unknowns which satisfy all the given equations at the same time. They are Simultaneous Equations because the equations are solved at the same time. Simultaneous Equations need algebraic skills to find the values of letters within two or more equations."

Given, The equations

[tex]2x + 3y = 10[/tex] ----------- eq 1

[tex]4x - y = -1[/tex] ------------ eq 2

multiplying eq 1 by 2

[tex]4x + 6y = 20[/tex] ----------- eq 3

now subtracting eq 3 from eq 2

we get, [tex]7y = 21[/tex]

y = 3 and x = 1/2

Hence, the values of x and y = 1/2, 3 respectively.

Answer:

- [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope (gradient) and c the y- intercept )

Given

2y = - 3x - 8 ( divide all terms by 2 )

y = - [tex]\frac{3}{2}[/tex] x - 4 ← in slope- intercept form

with gradient = - [tex]\frac{3}{2}[/tex]

The gradient of the straight line 2y = -3x - 8 will be -1.5.

A straight line is a combination of endless points joined on both sides of the point.

A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.
The slope(gradient) 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that the equation of the line is, 2y = -3x - 8

Rearrange the equation in the standard form of the equation as

2y = -3x - 8

y=-3/2 x-8/2

y= -1.5x - 4

Compare the obtained equation with the standard equation,y=mx+b. Where m is the gradient of the straight line.

m= -1.5

Thus, the gradient of the straight line 2y = -3x - 8 will be -1.5.

Answer:

10:25 AM

Step-by-step explanation:

Solving the question above, we are total that:

On Wednesday at camp, Melissa went for a hike at 6:30 A.M. The hike took 2 hours and 55 minutes. As soon as she got back from the hike, Melissa played volleyball for 1 hour.

The time that Melissa finished playing volleyball is calculated as:

6:30AM + 2 hours 55 minutes + 1 hour

= 6:30 am + 3 hours 55 minutes

= 9:85 minutes

60 minutes = 1 hour

85 minutes = 1 hour 25 minutes

= 10:25 AM

Hence: Melissa would finish playing volleyball at 10:25 AM

Answer:

y=5/2x-16

Step-by-step explanation:

First, we want to find the slope of the original line.

m= -4+8/-1-9

m= 4/-10

m= -2/5

Because we want the perpendicular bisector, we will need the slope to be the opposite reciprocal. Therefore, our slope is

m=5/2

Now, we want to find the midpoint of the line.

9-1/2

8/2=4

-8-4/2

-12/2= -6

So, the midpoint is (4,-6)

Using the information we have, we now can find b.

-6=5/2(4)+b

-6=10+b

-16=b

That gives us our equation

y=5/2x-16

Answer:

51 and  -27

Step-by-step explanation:

The sum of two numbers is 24 and their difference is 78. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 24. In other words, x plus y equals 24 and can be written as equation A:

x + y = 24

The difference between x and y is 78. In other words, x minus y equals 78 and can be written as equation B:

x - y = 78

Now solve equation B for x to get the revised equation B:

x - y = 78

x = 78 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 24

78 + y + y = 24

78 + 2y = 24

2y = -54

y = -27

Now we know y is -27. Which means that we can substitute y for -27 in equation A and solve for x:

x + y = 24

x + -27 = 24

X = 51

Summary: The sum of two numbers is 24 and their difference is 78. What are the two numbers? Answer: 51 and -27 as proven here:

Sum: 51 + -27 = 24

Difference: 51 - -27 = 78

Answer:

The numbers are 27 and 51

Explanation

x - y = 24

x + y = 78

Add together the equations

2x = 102

x = 51

Put into equation

51 - y = 24

27 = y
