Answer:

Step-by-step explanation:

3x9=27

4x7=28

Your son is 3 years old now

Step-by-step explanation:

If you do 9 times 3, you would get 27, and when you do 4 times 7, you would get 28. So, it makes sense since you get 1 year older and you are 9 times as old and then you will be 7 times as old. So, right now, your  son is 3 years old.

Answer:

a. 0.8x+1.25y

b. $5.70

Step-by-step explanation:

a. Let x represent the number of apricot bars and y represent the number of cranberry bars. A apricot bar costs 0.80 each and cranberry bars cost 1.25 each. So the expression for the income is 0.8x+1.25y.

b. To find the answer, plug in values to the previous expression. Since Kayley bought 4 apricot bars and 2 cranberry bars, plug in 4 for x and 2 for y.

0.8(4)+1.25(2)= 5.70

So, she spent $5.70.

Start by isolating the x term which is 20x by dividing both sides by 20.

That leaves you with x = 10/20 which can be reduced to x = 1/2.

Answer:

127 degrees

Step-by-step explanation:

Sum of interior angle is 720 degrees so to find x, just use 720 minus all the other angles

Polygon: a figure formed by coplanar segments

with one distinct interior region

Figure A, Figure B, and Figure D would be considered polygons.

Notice that those figures I mentioned above are

composed of line segments, and nothing else.

In addition, these figures don't have two separate

interior regions and figures that do aren't polygons.

Figure C would not be a polygon because

it's formed by a curve rather than line segments.

2. the slope is -10 and y-intercept is 1

Step-by-step explanation:

hope this helps!

Answer:

B. The slope is –10, and the y-intercept is 1.

Step-by-step explanation:

Our equation is y = -10x + 1. Notice that this is of the form y = mx + b, which is called the slope-intercept form because it literally gives us the slope and y-intercept in the equation:

- m: this is the slope value

- b: this is the y-intercept

Here, m = -10, which means the slope is -10. Also, b = 1, so the y-intercept is 1.

Thus, the answer is B.

Based on the information and graph provided, the number of years had temperatures within one standard deviation of the mean is 25 years.

Frim the data provided:

From the graph, the number of years within one standard deviation of the mean temperature is:

The total number of years, N:

N = n1 + n2 + n3 + n4 + n5 + n6 + n7 + n8 + n9

N =  2 + 3 + 2 + 4 + 3 + 3 + 5 + 2 + 1

N = 25 years  

Therefore, the number of years had temperatures within one standard deviation of the mean is 25 years.

Answer:

6x + 2y = 21.50 equation (i)

10x + 7y = 53.25 equation (ii)

Where x represent game and y represent ride.

Cost of 1 game = $2

Cost of 1 ride = $4.75

Step-by-step explanation:

To solve this question, we have to write two set of equations, each giving details of account of the two parties involved.

Let x represent games

Let y represent rides

So, with Arianna,

6x + 2y = 21.50.......equation (i)

With Alexa,

10x + 7y = 53.25 ........equation(ii)

We can solve this equations and go ahead to find the cost of ride and game using simultaneous equation

From equation (i)

6x + 2y = 21.50

Make x the subject of formula,

6x = 21.50 - 2y

x = (21.50 - 2y) / 6 ......equation (iii)

Put equation (iii) into equation (ii)

10x + 7y = 53.25

10 [(21.50 - 2y) / 6] + 7y = 53.25

(215 - 20y) / 6 + 7y = 53.25

(215 - 20y + 42y) / 6 = 53.25

215 + 22y = 53.25 × 6

215 + 22y = 319.5

22y = 319.5 - 215

22y = 104.5

y = 4.75

Put y = 4.75 in either equation (i) or (ii) to find x.

From equation (i)

6x + 2y = 21.50

6x + 2(4.75) = 21.50

6x + 9.5 = 21.50

6x = 21.50 - 9.5

6x = 12

X = 12 / 6

X = 2

Therefore the cost of 1 game is $2 and 1 ride is $4.75

The system of equations are,  [tex]6x+2y=21.5[/tex] and [tex]10x+7y=53.25[/tex]

where cost of each game is x dollar and cost of each ride is y dollar.

Let us consider that cost of each game is x dollar and cost of each ride is y dollar.

Since, Arianna played 6 games and went on 2 rides and spent a total of $21.50.

                      [tex]6x+2y=21.5[/tex]

and Alexa played 10 games and went on 7 rides and spent a total of $53.25.

                    [tex]10x+7y=53.25[/tex]

Hence, the system of equations are,  [tex]6x+2y=21.5[/tex] and [tex]10x+7y=53.25[/tex]

$338.50

Step-by-step explanation:

Simple interest would be i = ($2500)(0.09)(1.5 yrs)  =  $338.50

Answer:

(2, 1 )

Step-by-step explanation:

Given the 2 equations

y = 2x - 3 → (1)

y = - 2x + 5 → (2)

Substitute y = 2x - 3 into (2)

2x - 3 = - 2x + 5 ( add 2x to both sides )

4x - 3 = 5 ( add 3 to both sides )

4x = 8 ( divide both sides by 4 )

x = 2

Substitute x = 2 into either of the 2 equations for corresponding value of y

Substituting into (1)

y = 2(2) - 3 = 4 - 3 = 1

Solution is (2, 1 )
