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.

Answer:

40c=120

Step-by-step explanation:

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

25 lessons that cost $125

Step-by-step explanation:

If 8 lessons cost $96

then, 96/12 =8

therefore a lesson costs $8

If 25 lessons costs $125

then, 125/25= 5

therefore a lesson costs $5 which is cheaper.

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

Answer:

option 3

Step-by-step explanation:

Δ AEB and Δ ADC are similar, so ratios of corresponding sides are equal, that is

[tex]\frac{AB}{AC}[/tex] = [tex]\frac{AE}{AD}[/tex] , substitute values

[tex]\frac{9.2}{AC}[/tex] = [tex]\frac{9}{14}[/tex] ( cross- multiply )

9AC = 128.8 ( divide both sides by 9 )

AC ≈ 14.3 (to the nearest tenth )

Step-by-step explanation:

On the graph, the vertex is where the bottom of the U is. In general, it's always that same place on the U, but the U could be turned upside down or left or right. 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.

Put everything as a fraction. The first spot after the decimal means you put the number over 10, the second place means you put it over 100, the third 1,000, fourth 10,000 and so on. Hope I helped! ^^Step-by-step explanation:

The closeness of the given function is found to be by writing it in the simplest form as 1.

A fraction is a number written in the form a / b, where a and b are integers and b ≠ 0.

The number a is called as the numerator and b is the denominator.

The given fraction is 15/20.

It can be simplified as below,

Divide numerator and denominator by the common factor 5 as,

(15 ÷ 5)/(20 ÷ 5)

⇒ 3/4

The given fraction 3/4 is greater than zero and closest to 1.

Hence, the given fraction is closest to integer 1.

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

The amount of interest is $1170.

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.
