What is the system of equations?

A system of equations is a collection of one or more equations that are considered together. The system can consist of linear or nonlinear equations and may have one or more variables. The solution to a system of equations is the set of values that satisfy all of the equations in the system simultaneously.

Let's use the given information to set up a system of equations to solve for Ryan's age.

We know that Ryan's age, y, is twice Chaise's age, x, so we can write:

y = 2x (Equation 1)

We also know that Ryan is 11 years older than Chaise, so we can write:

y = x + 11 (Equation 2)

Now we can substitute Equation 1 into Equation 2:

2x = x + 11

Simplifying, we get:

x = 11

So Chaise is 11 years old.

To find Ryan's age, we can use either Equation 1 or Equation 2. Let's use Equation 2:

y = x + 11

y = 11 + 11

y = 22

Therefore, Ryan is 22 years old.

Answers

Answer:

mode: none

median: 4

mean: 4.2

Step-by-step explanation:

when dealing with mean, median, mode the first thing you should do is arrange the numbers in order from least to greatest. Once you have done so the easiest thing to do first is see which number is in the very middle, this is your median. Mode is the number that appears the most. Mean is another word for average. To find the mean, add up all the numbers then divide the sum of all the numbers by how many numbers are listed. In this case, 2+3+4+5+7=21.

21 divided by 5 (how many numbers there are) = 4.2

Looking at the bottom of the U, count on the x axis first (left 2, which is negative). That's your first number. Then count on the y axis (down 1, again, negative). That's your second number.

Answer:

I tried, but I'm not a math whiz or anything.

The amount of interest is $1170.

What is the compound interest?

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].

Given that, principal =$6500, rate of interest =4.25% and time period = 4 years.

Here, Amount = 6500(1+4.25/100)⁴

= 6500(1+0.0425)⁴

= 6500(1.0425)⁴

= 6500×1.18

= $7670

Interest = Amount-Principal

= 7670-6500

= $1170

Therefore, the amount of interest is $1170.

Sasha paid $68 for a painting frame during a 20% sale event. Find the original price of the frame.

Answers

Answer:

$68.20

Step-by-step explanation:

Answer:

85$

Step-by-step explanation:

p = original price

68 = p - 20%p

68 = p - 0.20p

68 = 0.80p

85 = p

The original price was $85.

The original price is 100%. The sales price was 20% off - subtract. So the sale price was 100% - 20% = 80%.

Incase you wanna know how I came up with the 0.80p :)

can someone help me find the equation for this line please

Answers

Answer:

y = x + 1

Step-by-step explanation:

The line y = x  goes through the origin, and forms a perfect 45 degree angle with the x axis.

This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.

Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so

y = 1x + 1 = x + 1

y = x + 1
