Solve the equation for x.​

Solve The Equation For X.

Answers

Answer 1

Answer:

Step-by-step explanation:

x/13=10

We have to get rid of the 13. (the denominator)

How?

By multiplying 2 sides by 13

Remember the Rules of Maths:

1. Whatever you do to one side, you must do to the other.

2. Use the opposite operation.

So, we used Rule 2 to get rid of the 13.

Now:

x=10*13

(On the left side, the 13s cancel)

x=130

It is always a great idea to double-check

Does 130 divided by 13 equal 10?

Of course it does!

Have a great day!!

I hope everything is clear!

What is the value of x?

Answers

Answer:

x = 80 degrees

Step-by-step explanation:

First look at the upper triangle.  There are two 65 degree angles there, along with two equal sides.  The angles must sum up to 180 degrees.  Therefore:

2(65) + x = 180; thus, the value of x is 50 degrees.

Next, recognize that the vertical angles in the middle of the diagram are equal and are 50 degrees each.  Thus, the smaller triangle has two 50-degree angles.  Again we sum up the angles, obtaining 50 + 50 + x = 180, or x = 80 degrees

An apple-juice container has a tiny hole in it, so it is slowly leaking. If the container leaks three

ounces every 19 minutes, how long will it take for the 16 ounces of juice in the container to leak

out? Write a proportional equation and solve with J.R.'s strategy of using a Giant One. 3 id

14

Answers

Answer:

101.33333 minutes

Step-by-step explanation:

Given :

Leakage rate = 3 ounces per 19 minutes

Time it'll take for 16 ounces of juice in the container to leak out

The leakage rate on ounce per minute :

3 ounces / 19 minutes = 0.1578947 ounce per min

1f 0.1578947 ounces leak out in 1 minutes

16 ounces will leak out in x minutes

Hence ;

0.1578947x = 16 ounces

x = 16 / 0.1578947

x = 101.33335 minutes

OR :

3 ounces = 19 minutes

1 ounce = (19 / 3) = 6.333333 minutes

16 ounces = (15 + 1) ounce

15 ounces = 3 * 5

Hence, 15 ounces will leak in (19 minutes * 5) = 95 minutes

1 ounce = 6.33333 minutes

Hence,

16 ounces will leak in (95 minutes + 6.33333 ounces) = 101.33333 minutes

HENCE, All 16 ounces will leak out in 101.33333 minutes

You are choosing between two plans at a health club. Plan A offers an initial membership fee of $75. And you pay $15 per month. Plan B offers an initial membership fee of $20 and you pay $26 a month. How many months are the two clubs the same price?

Answers

Answer:

5 months

Step-by-step explanation:

Let the number of months equalising both plans fee = x

Plan A total fee = 75 + 15x , Plan B total fee = 20 + 26x

Equalise both: 75+15x = 20+26x ; 75-20 = 26x-15x ; 55 = 11x ; x = 55 / 11

x = 5  

Proof : 75 + 15 (5) = 20 + 26 (5) ; LHS 150 = RHS 150

Answer:

Step-by-step explanation:

arc JL = 180° ( JL is a diameter ), then

arc KL = 180° - 31° = 149° , so

9x + 23 = 149 ( subtract 23 from both sides )

9x = 126 ( divide both sides by 9 )

x = 14

Answer:

X=14

Step-by-step explanation:

360-31-31=298

298/2=149

149-23=126

126/9=14

Bernice uses the equation C = 2h + 8 to find the total cost, C, in dollars, of renting a boat for h hours. If Bernice does not spend more than $32, what is the maximum number of hours she can rent the boat?
a 8
b 12
c 20
d 22​

Answers

Answer:

A

Step-by-step explanation:

Since she's not spending more than $32, the equation is 2h + 8 ≤ 32.

Isolate h to find the maximum number of hours she can rent the boat:

2h + 8 ≤ 32

First, subtract 8 from both sides.

2h ≤ 16

Then divide both sides by 2.

h ≤ 8

h, the number of hours, must be less than or equal to 8, so 8 is the maximum number of hours Bernice can rent the boat for.

Express the following in the form a + bi, where a and b are real numbers:
[tex] \sqrt{60i - 11} [/tex]
​

Answers

The equivalent of the complex number expression is [tex]\sqrt{60i - 11}[/tex] is 2 + 15i

How to rewrite the expression?

The complex number expression is given as:

[tex]\sqrt{60i - 11}[/tex]

Rewrite as:

[tex]a + bi = \sqrt{60i - 11}[/tex]

Take the square of both sides

[tex]a^2 + 2abi - b = 60i - 11[/tex]

By comparison, we have:

a^2 - b = -11

2ab = 60

Divide both sides by 2

ab = 30

Using a graphical tool, we have:

a = 2,b = 15

So, we have:

a + bi = 2 + 15i
