Write and solve an equation that can be used to find x, in the figure below:

Answers

Answer: x=40

Step-by-step explanation:

so you would add the two angles you already know.

30+63=93

The sum of the angles of a triangle is always 180°. Knowing this, you can do

180-93=87

so you know the third angle is 87°

plug this into the equation: 2x+7

2x+7=87

subtract both sides by 7

2x=80

divide by two

x=40

The correct answer is X=40 because

1. Add the 2 angles you already know.

30 + 63 = 93

2. The sum of all angles in a triangle is always 180°

180 - 93 = 87

3. third angle is 87°

2x + 7 = 87

4. Subtract BOTH sides by 7

2x = 80

5. Divide by 2

X = 40

When a number is decreased by 54%, the result is 28. What is the original number to the nearest tenth?

Answers

Answer:

x=60.9

Step-by-step explanation:

Let x represent the number

x - 54%x = 28

x - 0.54x = 28

0.46x = 28

Divide both sides by 0.46

x = 28/0.46

x = 60.86

x = 60.9

For Each coin, state its worth as a percentage of $1?

Answers

Answer:5. is 500%

Step-by-step explanation:

4. Is 250%, and 5. Is 500%

Explanation:
For #4, the coin is equal to $2 1/2, or $2.50. Since the question is asking the worth of each coin as a percentage of $1, $2.50 will be a percentage greater than 100%. $2.50 is 2.5x $1, so if $1 is seen as 100% in this problem, we can do 100 x 2.5. This is how you get the answer of 250%

You use the same method for question 5, except $5 is 5x $1, so we can do 100 x 5 to get 500%

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

In the figure, lines a and b are parallel.

Now, By definition of alternate and corresponding angles, we get;

⇒ m ∠1 = m ∠ 5

⇒ m ∠6 = 75°

And, By definition of linear pair of parallel lines,

⇒ m ∠2 + m ∠5 = 180°

Thus, All the correct statements that are true,

⇒ m ∠1 = m ∠ 5

⇒ m ∠2 + m ∠5 = 180°

⇒ m ∠6 = 75°

25. y=2x+1

26. $13

Step-by-step explanation:

25. 2x is the cost each day or the x, and the 1 is the initial fee, I found this because it said one day costs $3 and if I know that one days fee is $2 then I know that the y intercept or the price it starts at also known as a fee is $1. This is also backed up in the 4 day statement saying that 4 days is 9 dollars. I can do 9-1 to take away the fee and 8/2=4 so it is correct.

26. Since I already have the equation I can just plug in the vales and solve. y=2x+1, x=2 or the daily cost so 12+ (the fee) 12+1=13 so $13.

good luck, and have a great day.    :)

For 25 the answer would be y = 2x +

Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)
Can you please help?
the points (z,0) and (4,6) fall on a line with a slope of 6. What is the value of z?
If its not right im gonna report you

Answers

Answer:

z = 3

Step-by-step explanation:

First we want to find out how they found the slope of the line. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(6 - 0)/ (4 - z)

Simplify the parentheses.

= (6) / (4 - z)

Simplify the fraction.

= 6/(4 - z)

it is given that 6 is your slope. So let's add 6 to the left side of the equal sign.

6 = 6 / (4 - z)

To solve for z, we need to multiply both sides by (4 - z)

(4 - z)6 = 6

Now, divide both sides by 6 to isolate the expression of (4 - z)

4 - z = 1

Add z to both sides so it becomes positive.

4 = z + 1

Subtract 1 from both sides to isolate z.

3 = z

This is your answer.

Let's check it by plugging it back into the slope formula.

(6 - 0)/ (4 - z)

(6 - 0)/ (4 - 3)

= 6/1

= 6

Your answer is correct.

Joni earns $300 per week. If she gets a 25% raise, how much more money will she earn each week?

Answers

Answer:

$375 ($75 more dollars)

Step-by-step explanation:

25% of 300 is 75, so, 300+75 is 375.

Answer:

[tex]\huge\boxed{$75}[/tex]$75

Step-by-step explanation:

Joni currently earns $300 per week (given)

To find how much more she will earn each week, write an expression adding the original pay and the raise amount.

$300 + 25%

Find 25 as a decimal for multiplication

25%  = 25/100 = 0.25

Write an expression to represent the scenario

Expression example 1:

$300 + 0.25(300)

This expression adds the original pay and the new raise together.

Expression example 2:

$300 (1.25)

This expression already takes the new pay into account by finding 125% of the original pay.

Simplify both expressions

Expression 1:

$300 + 0.25(300)

$300 + $75

$375

Expression 2:

$300 (1.25)

$375

Both expressions represent the same scenario and therefore come out to the same result. Now that we know how much Joni made after the raise, we need to find how much more money she will earn in a week with the following equation.

New amount - original amount = amount increase

Substitute known values into the equation

$375 - $300

Simplify

$75

Joni will earn $75 more each week.
