Answer:
18 weeks
Step-by-step explanation:
So, Hugo received $100 for his birthday.
He saved $20 per week. Let x denote the weeks that passed. Therefore:
[tex]y=100+20x[/tex]
This equation represents the total money y Hugo has after x weeks.
The printer cost $460. Thus, set y to $460:
[tex]460=100+20x[/tex]
Solve for x.
Subtract 100 from both sides:
[tex]360=20x[/tex]
Divide both sides by 20:
[tex]x=18[/tex]
Therefore, it took Hugo 18 weeks to save up $460.

The horizontal distance of E is 9 units to the east of point F. Determine the coordinates of F if the coordinates of E are (3,8).
Answer:
(-6,8)
Step-by-step explanation:
By reading the question you can determine that point E is to the east, or the right, of point F by 9 units. This ultimately means you must subtract 9 units on the horizontal (x-axis) in order to get to point F.
In a certain grocery store, strawberries cost $4.96 per pound ( 4.96 dollars/lb d o l l a r s / l b ). What is the cost per ounce?
Cost of the strawberry will be $0.31 per ounce.
Given in the question,
Strawberry cost → $4.96 per poundWe can write the cost as [tex]\frac{4.96\text{ Dollars}}{1\text{Pound}}[/tex].
Since, 1 pound = 16 ounces
To convert the cost of the strawberry in dollars per ounce, multiply the price by the conversion factor [tex]\frac{1\text{ Pound}}{16\text{ Ounces}}[/tex].
So the cost of strawberry = [tex]\frac{4.96\text{ Dollars}}{1\text{Pound}}\times \frac{1\text{ Pound}}{16\text{ Ounces}}=0.31\text{ Dollars per ounce}[/tex]
Therefore, cost of the strawberry will be $0.31 per ounce.

Answer:
Saldo bancario= $1,192
Step-by-step explanation:
Dado la siguiente información:
Saldo del banco= -$2,376.5
Depósito= $3,568.5
Ella tenía una cuenta en negativo. El depósito le ayuda a cubrir el sado y pasar a tener un saldo positivo. Ahora calculamos cuánto le queda en la cuenta.
Saldo bancario= -2,376.5 + 3,568.5

If M is the midpoint of XY, XM=2x+5 and YM=25, find XY.
Answer:
50
Step-by-step explanation:
Since M is the midpoint of XY, this means that XM and MY must be equivalent from the definition of midpoint.
So:
[tex]XM=MY[/tex]
The entire length of the segment (XY) is:
[tex]XY=XM+MY[/tex]
We know that XM is equivalent to MY. Substitute MY for XM:
[tex]XY=MY+MY[/tex]
Combine like terms;
[tex]XY=2MY[/tex]
We are told that YM (or MY) is 25. So:
[tex]XY=2(25)[/tex]
Multiply:
[tex]XY=50[/tex]
So, the length of XY is 50.
And we're done!

A rectangle has side lengths of 2 units and 4 units. Can you form a different quadrilateral using the same four side lengths? Explain why or why not Support your explanation with drawings. please explain this for me. im so lost
Answer:
a kite
Step-by-step explanation:
Yes, you can form a kite. The top two would be 2 units, and the bottom two would be 4 units. It would still have two of each, just like the rectangle, but would be a different quadrilateral.
Alternately, you could turn the rectangle into a parallelogram by leaning it. Rectangles have 90 degree angles, so it wouldn't be a rectangle anymore.

if ( 3x + 2) (5x + 1) = ax2 + bx + 2
What is the value of a - b ?
a - b= 2
Step-by-step explanation:
expanding the brackets
we have 15x^2+13x+2
a= 15 b= 13
thus, a-b =15-13
=2
The value of a - b if, (3x + 2) (5x + 1) = ax² + bx + 2 is 2 i.e a - b = 2.
What is expression?At least two numbers or variables, one or more arithmetic operations, and a statement are all required components of a mathematical expression. The term "expression" or "mathematical expression" refers to a finite collection of symbols that are well-formed in line with context-dependent criteria.
Given:
(3x + 2) (5x + 1) = ax² + bx + 2
Write the left term of the equation in the format of the right term,
3x (5x + 1) + 2(5x + 1)
15x² + 3x + 10x + 2
15x² + 13x + 2
Compare the above equation to ax² + bx + 2,
a = 15 and b = 13
Calculate the value of a - b as shown below,
a - b = 15 - 13

three times the sum of a number and 15 is 24
Answer:
[tex]\huge\boxed{\sf x = -7}[/tex]
Step-by-step explanation:
Let the number be x
So,
=> The sum of number and 15 is x + 15
=> Three times will be 3(x+15)
Given that it equals 24
So, the given condition is:
3(x+15) = 24
Resolving Parenthesis
3x + 45 = 24
Subtracting 45 to both sides
3x = 24 - 45
3x = -21
Dividing both sides by 3

Dash offers and unlimited talk and texting plan for $80 per month AB&C charges $0.20 per text message and $55 for 1,000 min of talk time per month Horizon charges $0.10 per text message and $75 for 1,000 minutes of talk time per month what is the equation for each of them and which phone bill should I go with
Answer:
Let's define x as the number of text messages send.
y as the number of 1,000 minutes talk per month.
(so we can write y = N/1000) where N is exactly the number of minutes that you talked that month.
> The equation for Dash is:
C1(x, y) = $80
>The equation for AB&C
C2(x,y) = $0,20*x + $55*y
> Horizon
C3(x,y) = $0.10*x + $75*y.
Now, which company you should go for?
Well, it depends on the values of x and y that you have.
if in your case you have x > y, you may want to go with Horizon, because the price per text is smaller.
if you usually talk, you may want to go with AB&C because the slope for y is smaller.
If you send a lot of texts and talk a lot, then Dash is the best option, because there is no dependence with the variables x, y

In the 21st century, people measure length in feet and meters. At various points in history, people measured length in hands, cubits, and paces. There are 9 hands in 2 cubits. Write an equation to express the relationship between hands, LaTeX: hh, and cubits, LaTeX: cc. Explain your reasoning under your equation.
Answer: 1 hand = 0.22... cubits.
Step-by-step explanation:
We want to write the relation between hands and cubits.
We know that there are 9 hands in 2 cubits.
So we can write:
9 hands = 2 cubits.
Now, we want to have an unit in the left side (so we can see how many cubits are equal to exactly one hand).
Then we can divide by 9 in both sides of the equality.
(9 hands)/9 = (2 cubits)/9
1 hand = 0.22... cubits.
Answer:
22.5 hands = 3 paces
