In The Diagram Below, Find The Value Of Y.

Answers

Answer 1

Answer:

y=130

Step-by-step explanation:

1) combine all like terms for the inside angles of the triangle

(3x-19) + (4x+8) + (x+7)3x-19+4x+8+x+78x-4

2) because the sum of all angles = 180 add that to the sum of all like terms

8x-4=180add 4 on both sides and divide both sides by 8this should be x=23

3) now you replace the x's with 23

(3(23) -19)69-1950

4) now we know that (3x-19)=50

5) take 180 and subtract 50

this is because y and (3x-19) creates a supplementary angle which also equals 180

6) 180-50=130

B. 1
C. 4
D. 5​

Answers

Answer:

D. 5

Step-by-step explanation:

Assuming 1 box = 1 unit on the coordinate grid, therefore:

Coordinate of point P on the graph = 1

Coordinate of the point at which the ray from point P meets at line n = -4

Distance from P to n = |1 - (-4)|

= |1 + 4|

Distance from P to n = 5 units

The answer is D. 5

Answers

Answer:

n = 2/3

Step-by-step explanation:

3n - 22 = -20

Add 22 to both sides

-20 + 22 = 2

3n = 2

Divide both sides by 3

2 / 3 = 2/3

n = 2/3

Let me know if I've done something wrong :)

Answer:

[tex]n = \frac{2}{3}[/tex]

Step-by-step explanation:

Add 22 to each side, so it now looks like this: 3n = 2Divide each side by 3 to cancel out the 3 next to n. It should now look like this: [tex]n = \frac{2}{3}[/tex]

10 oranges and 20 grapefruits weigh 35 pounds total. 16 oranges and 10
grapefruits weigh 23 pounds total. How much would 13 oranges and 15
grapefruits weigh?
A 28 pounds
B 29 pounds
C 30 pounds
D 58 pounds

Answers

Answer:

B

Step-by-step explanation:

oranges weigh 0.5 and grapefruits weigh 1.5

The required: 13 oranges and 15 grapefruits would weigh 29 pounds.

The correct option is A.

What is the system of equations?

One or many equations having the same number of unknowns that can be solved simultaneously are called simultaneous equations. And the simultaneous equation is the system of equations.

Let's use a system of equations to solve this problem:

Let's call the weight of an orange "x" and the weight of a grapefruit "y". Then we can write:

10x + 20y = 35 (equation 1)

16x + 10y = 23 (equation 2)

We want to find the weight of 13 oranges and 15 grapefruits, which we can represent as:

13x + 15y

In this case, we can multiply equation 1 by -8 and equation 2 by 15:

-80x - 160y = -280 (equation 1, multiplied by -8)

240x + 150y = 345 (equation 2, multiplied by 15)

Now we can add the two equations to eliminate y:

160x = 65

Solving for x, we get:

x = 65/160

Now we can substitute this value of x back into one of the original equations to solve for y. Let's use equation 1:

10(65/160) + 20y = 35

Simplifying this equation, we get:

13/32 + 2y/4 = 7/2

Multiplying both sides by 32, we get:

13 + 16y = 112

Solving for y, we get:

y = 99/16

Finally, we can substitute these values of x and y into the expression for 13 oranges and 15 grapefruits:

13x + 15y = 13(65/160) + 15(99/16) = 29.0625

Therefore, 13 oranges and 15 grapefruits would weigh approximately 29.0625 pounds, which is closest to answer B, 29 pounds.

What is the slope of 1.5x+4.5y=18 ,and how do you know?​

Answers

Answer:

m=-1/3

Step-by-step explanation:

The slope of this line is m=-1/3 because if you use the slope-intercept formula, y=mx+b, m is the slope. If you take this equation and plot two points on a line that has this equation, the slope will be negative if the line forms an obtuse angle on the 0 line. In this case, m=-1/3 as the line goes back 1/3 unit for every unit in this equation. Hope it helps!

Answer:  the slope is -0.33...   The does means that 3 is repeating.

Step-by-step explanation:

First we will convert the equation into slope intercept form, which is the same way of solving for y in the equation.

1.5x + 4.5y = 18     Solve for y by first subtracting 1.5x from both sides

-1.5x               -1.5x

4.5y  = 18 - 1.5x     Now divide both sides by 4.5

y= 4- 0.33x

y= -0.33x + 4    Now the slope is the coefficient of the variable x which is the number that comes after the variable.

In this case, the slope is -0.33...

Think about it this way: The x axis goes from left to right, correct? So just try to visualize actually picking up the object and flipping it over that axis. So since one tip of the triangle is on the coordinate (1,1), after reflecting the shape that same tip would be on (1,-1). You understand?
