Find the measure of an angle and its complement if one angle measures 18 degrees more than the other?

Answers

Answer:

x+18=90-x

use this equation and solve

2x=72

x=36

36+18=54

90-54=36

54 degrees and 36 degrees

The solution is,  the measure of an angle and its complement are, 54 degrees and 36 degrees.

What is an angle?

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

We know that, a ray is a line that continues on forever inn one direction with a point at it's start.

here, we have,

let, one angle = x

x+18=90-x

use this equation and solve

2x=72

x=36

so, we get,

36+18=54

90-54=36

Hence, The solution is,  the measure of an angle and its complement are, 54 degrees and 36 degrees.

The solution to the equation 2 = -(7/4) + (1/4)x is x = 15

What is an equation?

An equation is an expression used to show the relationship between two or more numbers and variables.

Given the equation:

2 = -(7/4) + (1/4)x

Add 7/4 to both sides of the equation:

2 + 7/4 = -(7/4) + (1/4)x + 7/4

(1/4)x = 15/4

Multiply both sides by 4:

x = 15

The solution to the equation 2 = -(7/4) + (1/4)x is x = 15

x = -⁷/9

Step-by-step explanation:

[tex] \frac{9x - 8}{3} = \frac{9x - 3}{2} [/tex]

Multiply both sides by 3

[tex] \frac{9x - 8}{3}*3 = \frac{9x - 3}{2}*3 [/tex]

[tex] 9x - 8 = \frac{3(9x - 3)}{2} [/tex]

Multiply both sides by 2

[tex] 2(9x - 8) = \frac{3(9x - 3)}{2}*2 [/tex]

[tex] 2(9x - 8) = 3(9x - 3) [/tex]

[tex] 18x - 16 = 27x - 9 [/tex]

Subtract 27 from each side

18x - 16 - 27x = 27x - 9 - 27x

-9x - 16 = -9

Add 16 to both sides

-9x - 16 + 16 = -9 + 16

-9x = 7

Divide both sides by -9

-9x/-9 = 7/-9

x = -⁷/9

What is the slope and y-intercept of the following equation: y = -4 +2x

Answers

Answer:

slope = 2, y- intercept = - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

y = - 4 + 2x , that is

y = 2x - 4 ← is in slope- intercept form

with slope m = 2 and y- intercept c = - 4

14 = 3y - 4
Help me pls

Answers

Answer:

y = 6

Step-by-step explanation:

I'm going to assume you want to solve for y.

Step 1: Move all constants to 1 side, isolating y and its coefficient:

14 = 3y - 4

14 + 4 = 3y - 4 + 4

18 = 3y

Step 2: Divide both sides by 3 to solve for y:

3y = 18

3y / 3 = 18 / 3

y = 6

Final answer: y = 6

Answer is y=6
because move the variable to the left so hand side and change its sign -3y+14=-4
Move the constat to the right - hand side and change its sign
-3y=-4-14
Calculate the difference
-3y=-18
And your answer should be y=6 hope this helped

If you did not learn a different method for unit conversion in a previous class, respond to the following statement.

Explain how to use the unit-factor method to convert 120 pounds to kilograms.
Hint: 1 kilogram=2.2 pounds
To write the unit factors, use the / symbol, like this: 1 gallon/3.79 liters.

Answers

Answer:

120 pounds = 54.5 kilogram

Step-by-step explanation:

We know that,

1 kilogram=2.2 pounds

or

1 pound = (1/2.2) kilogram

We need to convert 120 pounds to kilograms.

[tex]120\ \text{pounds}=\dfrac{120}{2.2}\ \text{kilogram}\\\\=54.5 \text{kilogram}[/tex]

So, there are 54.5 kilograms in 120 pounds.

19/100+7/10 wich fraction can be used in place of 7/10 to find the value of the expression​

Answers

Answer:

70/100.

Step-by-step explanation:

When adding fractions, you need to find a common denominator.

This just means that the numbers at the bottom of both fractions you are adding must be the same.

So for 19/100 + 1/10, you need to match the two denominators (bottom numbers).

To do this, you need to multiply 10 by 10 to get 100.

What you do to the bottom, you must always do to the top as well.

So multiply 7 by 10 and get 70.

70/100 will replace 7/10.

Now you can add fractions because the bottom numbers are the same.

does anyone know the answer to 5(2t+3)=75 that can tell me how to find the answer not just the answer

Answers

Answer: Let me know if this helps.

Step-by-step explanation:

5(2t+3)=75     Distribute the 5 using multiplication. 5x2t and 5x3

10t+15=75      Subtract 15 because you need to get the t by itself.

10t = 60         Now divide by 10 to get t by itself. 10/10 and 60/10.

t = 6               Answer.

Answer:

t=6

Step-by-step explanation:

It's all about get t on one side of the equation, and so everything else on the other side of the equation.

The first thing we want to get rid of is the 5. The 5 is multiplied by (2t+3), so to get rid of it, we divide both sides by five (divide both sides since they must remain equal):

(5(2t+3))/5=75/5

2t+3=15

The next thing we can get rid of is the 3. Subtract 3 from both sides:

2t+3-3=15-3

2t=12

Now, we get rid of the 2. Divide both sides by 2:

2t/2=12/2

t=6

Jane was running for 2 hours and 25 minutes and reached her journey at 2:05pm. Calculate the time she started.

Answers

Answer:

11:40 am

Step-by-step explanation:

First, I started by subtracting 5 minutes from the additional 25 minutes of running that couldn’t fit into another hour. That would bring the running time to 2 hours and 20 minutes and the end time to 2:00 pm. Take away another 2 hours and you would be left with 20 minutes, with a start time of 12:00 pm. Get rid of the last 20 minutes and you get the start time as 11:40 am.

Check:

11:40 + 2 hours = 1:40 pm

1:40 + 20 minutes = 2:00 pm

2:00 + 5 minutes = 2:05

This is correct

Rewrite the formula to find the width of the base of the prism if the volume, length of the base, and height of the prism are already known.

Answers

Answer:

w = V/lh

Step-by-step explanation:

The volume of a rectangular prism is calculated using the formula V = lwh, where V is the volume of the prism, l and w are the length and width of the base of the prism, respectively, and h is the height of the prism.

Rewrite the formula to find the width of the base of the prism if the volume, length of the base, and height of the prism are already known.

volume of a rectangular prism,V = lwh

Where,

l = length of the base of the prism

w = width of the base of the prism

h = height of the prism

Rewrite the formula to find w

V = lwh

w = V/lh

That is,

width of the base of the prism = volume of the prism divided by length of the base of the prism multiplied by height of the prism
