Let the number = 10x+y
x+y = 9
y-x = 1
(x+y)+(y-x) = 9+1
2y = 10
y = 10/2
y = 5x+y = 9
9-y = x
x = 9 - 5
x = 4So, your number is 45... Hope this will help...
Find the value of x in the triangle shown below help please!!
Step-by-step explanation:
Hey there!!
It 's so simple.
You remember common property of triangle. (i.e sum of interior angle of a triangle is 180°)
So,
77° + 31° + x = 180°
x + 108° = 180°
x = 180° - 108°
Therefore the measure of angle x is 72°.
Hope it helps....
Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, what is Stephanie's age?
Answer: Stephanie is 15
Step-by-step explanation:
because you can do 24 divided by 2 which equals 12 then add three to 12 and you get 15.
you're welcome! plz lmk if i'm wrong XD
Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, then Stephanie's age is 15 years.
To find Stephanie's age, we need to follow the given information that her age is 3 years greater than half of her sister's current age.
First, we find half of her sister's age: Half of 24 = 24 / 2 = 12
Next, we add 3 years to half of her sister's age: 12 + 3 = 15
Therefore, Stephanie's age is 15 years.
Age can be used in mathematical equations and word problems to solve for unknowns or to establish relationships between different quantities. For example, age-related math problems might involve scenarios such as Finding someone's age given their birth year and the current year, Calculating the average age of a group of people and Determining the age difference between two individuals based on their birth years.

The volume of the cell phone is 75 cubic centimeters. Write and solve an equation to find the height of the cell phone. Round your answer to the nearest tenth
Answer:
Equation: [tex]Height = \frac{75}{Area}[/tex]
Step-by-step explanation:
The question is incomplete as the dimension of the phone was not given.
However, the following explanation will guide you
Given
[tex]Volume = 75\ in^3[/tex]
Required
Determine the Height
Volume is calculated as thus;
[tex]Volume = Area * Height[/tex]
Substitute 75 for Volume
[tex]75= Area * Height[/tex]
Divide through by Area
[tex]Height = \frac{75}{Area}[/tex]
The above represent the equation to solve for Height
To solve for height, we need the dimension of the phone or the area.
Take for instance; the length and width of the phone is 5 by 5 inches;
The height would be:
[tex]Height = \frac{75}{5 * 5}[/tex]
[tex]Height = \frac{75}{25}[/tex]
[tex]Height = 3\ inches[/tex]

4-7x=1-6x can someone please solve and show the work :)
Answer:
x = 3
Step-by-step explanation:
Simplifying
4 + -7x = 1 + -6x
Solving
4 + -7x = 1 + -6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6x' to each side of the equation.
4 + -7x + 6x = 1 + -6x + 6x
Combine like terms: -7x + 6x = -1x
4 + -1x = 1 + -6x + 6x
Combine like terms: -6x + 6x = 0
4 + -1x = 1 + 0
4 + -1x = 1
Add '-4' to each side of the equation.
4 + -4 + -1x = 1 + -4
Combine like terms: 4 + -4 = 0
0 + -1x = 1 + -4
-1x = 1 + -4
Combine like terms: 1 + -4 = -3
-1x = -3
Divide each side by '-1'.
x = 3
Simplifying
x = 3

have enough money in 4 years?
The family will not have enough money. They will have saved only $16,000.
O The family will not have enough money. They will have saved only $19,200.
The family will likely have enough money. They will have saved $16,000 and have accumulated interest.
O The family will likely have enough money. They will have saved $19,200 and have accumulated interest.
Answer:
The family will not have enough money. They will have saved only 19,200
Step-by-step explanation:
The family will not have enough money. They will have saved only $19,200 is the best statement.
What is interest?
" Interest is defined as the amount of money which one has to pay while borrowing and charged while lending money."
According to the question,
Amount saved per month by Hartman family = $400
Amount need to pay fees after 4 years = $20,000
Total amount saved in 4years = 400 × 12 ×4
= $19200
Difference in amount needed = 20,000 - 19,200
= $800
Here it is not given that Hartman family has saved money in any bank.
Neither rate of interest is mentioned.
Hence, we conclude that the family will not have enough money. They will have saved only $19,200 is the best statement.

-5 ≤ 1 - 2x < 9
Let's first break this down into two different inequalities.
1 - 2x ≥ -5
Subtract 1 from both sides.
-2x ≥ -6
Divide both sides by -2
x ≤ 3
Now, let's do the second inequality.
1 - 2x < 9
Subtract 1 from both sides.
-2x < 8
Divide both sides by -2
x > 4
let's combine each inequality to get our reduced compound inequality.
-4 < x ≤ 3
To plot this, put a hollow point at -4. A hollow point looks something like the letter o.
And put the second point at 3. This time, fill in the point so it looks whole.
Now, connect your points.
It should look something like this:

Answer:
x=9 Hope this helps :)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 3x from both sides.
Step 3: Subtract 6 from both sides.
Step 4: Multiply both sides by 3/(-8).
And you get x=9
