Given ABC, what is the value of x? Write the answer as a decimal number

Answers

Answer 1

9514 1404 393

Answer:

12.25

Step-by-step explanation:

The angle bisector divides the triangle sides proportionally, so we have ...

x/3.5 = 7/2

x = 3.5×7/2 . . . . multiply by the denominator

x = 12.25

_____

Additional comment

The proportion can be written 4 ways. I find it convenient to write it with the unknown value in the numerator. That way, the solution is found in one step: multiply by the denominator.

-3x + 15 < 18

Answers

Answer:

x > -1

Step-by-step explanation:

-3x + 15 < 18

Subtract 15 from each side

-3x + 15-15 < 18-15

-3x < 3

Divide each side by -3, remembering to flip the inequality

-3x/-3 > 3/-3

x > -1

How would you solve this?

Answers

Answer:

For the equation, you should subtract 2x on both sides to get -y = -2x - 4. Flip the y's negative sign to get a proper function which is y = 2x + 4. The y-intercept is at (0, 4) and each unit will move two units up along the x-axis.

50 – 5(4.3 – 1.3) ÷ 0.5

Answers

Answer:

(0.5, 1.3)(0.5, 1.3)

Step-by-step explanation:

Given equations are:

As we can see that the given equations are linear equations which are graphed as straight lines on graph. The solution of two equations is the point of their intersection on the graph.

We can plot the graph of both equations using any online or desktop graphing tool.

We have used "Desmos" online graphing calculator to plot the graph of two lines (Picture Attached)

We can see from the graph that the lines intersect at: (0.517, 1.267)

Rounding off both coordinates of point of intersection to nearest tenth we get

(0.5, 1.3)

Hence,

(0.5, 1.3) is the correct answer

what is the original price when the discount is 25% and the sale price is $40

Answers

Answer:

the original price was $53.33

Step-by-step explanation:

$x ---- 100%

$40 ------- 75% (this is because 25% of it's just 75% of the actual price)

[tex]75\cdot x = 100\cdot 40\\\\75x = 4000\\\\x=53.33[/tex]

Answer: 53.33 dollars

===============================================

Work Shown:

x = original price

25% = 25/100 = 0.25

25% of x = 0.25x = discount, or amount saved

final price = (original price) - (discount)

final price = (x) - (0.25x)

final price = 0.75x

0.75x = 40

x = 40/0.75

x = 53.333333

x = 53.33

The original price is $53.33

The discount, or amount saved, is 0.25*x = 0.25*53.33 = 13.3325 = 13.33 dollars.

This means the sale price is 53.33 - 13.33 = 40

We can also see this through computing 0.75*x = 0.75*53.33 = 39.9975 = 40, which matches with the given sale price.

Note how I'm rounding to the nearest penny when needed.

if they are 2 separate equations the first one is 1) 5(x-2) and the second one is 8(2p + 3c+4w )

Which equation represents a line which is perpendicular to the line 5x + 2y = 12?

Answers

Answer:

y = ²/₅ x - 3

Step-by-step explanation:

Changing to slope-intercept form:

5x + 2y = 12 {subtract 5x from both sides}

2y = -5x + 12 {divide both sides by 2}

y = -⁵/₂ x + 6

y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇔ m₁×m₂ = -1

{Two lines are perpendicular if the product of theirs slopes is equal -1}

y =-⁵/₂ x + 1 ⇒ m₁ = -⁵/₂

-⁵/₂× m₂ = -1 ⇒ m₂ = ²/₅

So, any line perpendicular to 5x + 2y = 12 must have slope m =²/₅

Liana hikes slowly away from her campsite for 30 minutes. Then she rests for 10 minutes,
Finally she hikes back to her campsite at a faster pace, reaching it in 20 minutes.
Which graph could represent Liana's distance from the campsite and time?

Answers

Answer:

The answer would be A

Step-by-step explanation:

The Y axis represents the distance Liana traveled from 0 (campsite). the X axis represents the amount of time.

Liana travels away from the campsite for 30 minutes (slope), and then she stops completely for 10 minutes (no Y axis moments). She then returns back to camp faster (minutes)

Every other answer is incorrect as they maintain a single block from the graph, and each block is counted as 5 minutes. The only answer that has that 10 minute wait is answer A

The correct graph of this situation is showing in Graph 2.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Liana hikes slowly away from her campsite for 30 minutes. Then she rests for 10 minutes,

And, Finally she hikes back to her campsite at a faster pace, reaching it in 20 minutes.

Now,

Let time is showing on x - axis.

And, Distance from campsite in on y - axis.

Hence, In graph 2;

Liana hikes slowly away from her campsite for 30 minutes. Then she rests for 10 minutes, And, Finally she hikes back to her campsite at a faster pace, reaching it in 20 minutes.

Answers

Combine costs
59.99(3) + 75 = 179.97 + 75
179.97 + 75 = $254.99 (total cost)
Now add tax: 8% = 0.08
254.99 * 0.08 = 20.3992
254.99 + 20.3992 = 275.3892
