Step-by-step explanation:

143x 69

Divide 143 to both sides

143x = 69

---------------     =  2.07

143      143

Step-by-step explanation:

Use the Distributive Property:

[tex]-10(-7x^{2} +5x)[/tex]

[tex]70x^{2}-50x[/tex]

[tex]70x^{2}-50x[/tex] is your simplified expression.

Step-by-step explanation:

I guess, the problem is to understand :

what means "average" ?

well, the average of a defined set of data points is the sum of the data divided by the number of data points (or samples).

that way you get a mean value for each time the system is "measured" (a data point is created).

each new measurement / data point changes the mean value (or average).

this is used all the time - in sports statistics (e.g. the average score of a team), in daily life (like the average height of a human being that defines sizes of clothes, beds, chairs, tables, even the typical height of ceilings and so on).

the average of these 8 data points is therefore :

(36+37+34+23+47+27+31+21)/8 = 256/8 = 32

so, if he wants to raise his average score to 35 with the results of the next 2 games, this has 2 things to be considered :

1. the number of days points will be then 8+2=10 (and not just 8).

2. we need to add 2 data points, so that the sum of all 10 data points divided by 10 is then 35.

(36+37+34+23+47+27+31+21+x+y)/10 = 35

(36+37+34+23+47+27+31+21+x+y) = 350

x + y = 350 - 256 = 94

that means, he has to score a total of 94 points in the next 2 games.

it does not matter, how many in any single game, as long as the sum of both games is 94.

since the question is phrased "how many in each of the next 2 games", we simply take the target average of these 2 games.

remember, sum/amount = 94/2 = 47.

so, he would have to score 47 points in each of the next 2 games to raise his general average score to 35.

Fractions help children understand the nature of numbers and their interactions (e.g., the meaning of division). If a child doesn't understand how fractions work, it will interfere with his ability to learn algebra later.

Answer:

no because micah started before and they are running at the same pace.

Step-by-step explanation:

If they maintain their pace, Luke will not catch up to Micah because the gap of the 2 miles will be maintained.

In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

It is given that Micah jogs at a 5 mph pace along a park trail. Luke begins running on the same path at a speed of five miles per hour after he has jogged two miles.

After 2 kilometers of jogging by Micah, Luke begins running along the same route. Luke moves at a 5 mph speed.

Because Micah and Luke move at the same speed. There will be a 2-mile separation between them. Luke will not catch up to Micah

Thus, if they maintain their pace, Luke will not catch up to Micah because the gap of the 2 miles will be maintained.

Answers:

Point in the original figure: (-7, 3)

Point in the final figure: (-2, 3)

===============================================

Explanation:

To translate 5 units to the right, we add 5 to the x coordinate. The y coordinate stays the same.

The symbolic way to write the rule would be to say [tex](x,y) \to (x+5, y)[/tex]

The original point is at (-7, 3). We add 5 to the x coordinate -7 to get -7+5 = -2. The y coordinate is 3 the whole time for both points.

That's how we go from (-7,3) to (-2,3)

Answer:

number is 7

Step-by-step explanation:

let the number be n , then

6n = 9n - 21 ( add 21 to both sides )

21 + 6n = 9n ( subtract 6n from both sides )

21 = 3n ( divide both sides by 3 )

7 = n

That is the number is 7

Answer:

Answer:

[tex]x = 12[/tex]

Step-by-step explanation:

the base length is 32

But we need the base angle for the x triangle so we say

[tex] \frac{32}{2} = 16[/tex]

[tex]20 = hypothenus \\ 16 = adjacent \\ [/tex]

[tex]opposite \: =[/tex]

[tex] {opp}^{2} + {adj}^{2} = {hyp}^{2} [/tex]

[tex] {opp}^{2} + {16}^{2} = {20}^{2} [/tex]

[tex] {opp}^{2} = {20}^{2} - {16}^{2} \\ {opp}^{2} = 400 - 256 \\ {opp}^{2} = 144 \\ opp = \sqrt{144} \\ opp = 12 \\ x = 12[/tex]

Answer:

no

Step-by-step explanation:

Doesn't add to 12

[tex] - 5x + y = 12[/tex]

Add both sides 5x

[tex] - 5x + 5x + y = 5x + 12[/tex]

[tex]y = 5x + 12[/tex]

&

[tex]y = - x[/tex]

Thus :

[tex] - x = 5x + 12[/tex]

Add both sides x

[tex] - x + x = 5x + x + 12[/tex]

[tex]0 = 6x + 12[/tex]

Subtract both sides 12

[tex]0 - 12 = 6x + 12 - 12[/tex]

[tex] - 12 = 6x[/tex]

Switch sides

[tex]6x = - 12[/tex]

Divide both sides by 6

[tex] \frac{6x}{6} = \frac{ - 12}{6} \\ [/tex]

[tex]x = - 2[/tex]

We found the x-coordinate of the solution point ; to find the y-coordinate we just need to put the value of x in one 0f the given equations :

[tex]y = - ( - 2) [/tex]

[tex]y = 2[/tex]

Thus ( - 2 , 2 ) is the solution to this system of equations.

Answer:

r = 12

Step-by-step explanation:

Step 1: Multiply both sides by 3.

Step 2: Check if solution is correct.
