correct? If so, explain the steps he used to solve the equation. If he is not correct, explain what he should have done to solve the problem.

Answers

Answer:

He is not correct.

Step-by-step explanation:

he should have done

4(x-1) = -1(6x-36)

=> 4x-4 = -6x+36

=> 4x-4+4 = -6x +36+4

=> 4x+6x = -6x+6x+40

=> 10x = 40

=> (10x)/10 = 40/10

=> x = 4.

Answers

Answer:

a = 65

d = 138

Step-by-step explanation:

d + 42 = 180

d = 138

c + d + 90 + 115 = 360

c + 138 + 205 = 360

c + 343 = 360

c = 17

90 + b + c = 180

90 + b + 17 = 180

b + 107 = 180

b = 73

a + b + 42 = 180

a + 73 + 42 = 180

A parallelogram with a height of 2x+3 has an area listed below. What is the length of the base of the parallelogram? 2x^2+13x+15

Answers

Answer:

x+5

Step-by-step explanation:

I thought what 2 numbers if multiplied made 15

also 2x+3 already has a 3

so I'm guessing 3 and 5

then I put them next to each other

(2x+3) ( +5)

I put a x in the second parenthesis as a guess because the area had a 2x^2 in it . that could only happen with 2x * x

so (2x+3) (x+5)

a game consists of randomly choosing a bag (labelled 1, 2 or 3) out of a choice of 100, and then again randomly, picking a ball (red or black) from it. Each bag has the same total of balls (10). the same player is going to play the game 200 times consecutively. how many black balls should he expect to pick

Answers

Answer:

hello your question has some missing information attached below is the missing information

answer :  112 black balls

Step-by-step explanation:

Given data:

Each bag contains ; 10 balls

Total number of ball = 100 balls

first: calculate the number of Black balls to be picked from the three bags

From bag 1 = 0.4 * 0.35 * 10 = 1.4 balls

From bag 2 =  0.8 * 0.45 * 10 = 3.6 balls

From bag 3 = 0.3 * 0.2 * 10 = 0.6 ball

Total black balls picked = 5.6

∴ percentage of black balls picked given that each bag contains 10

5.6 / 10 * Total balls available  =  56 balls = 56% of 100 balls

Hence If the player plays this game 200 times the number of black balls he will pick = 56% * 200 =  112 balls

Which of these systems of equations is shown in the graph?

Answers

Answer:

C) y = -x - 2; y = 4x + 3

Hope this helps

The solution is Option C.

The system of equations is y = - x - 2  ;  y = 4x + 3

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be represented as A

Let the second equation be represented as B

Now , the value of A is

y = - x - 2   be equation (1)

Now , the value of B is

y = 4x + 3   be equation (2)

On simplifying the equation , we get

The point of intersection on the graph is ( -1 , -1 )

Substituting the values in the equation , we get

when x = -1 and y = -1

y = - x - 2

-1 = - ( -1 ) - 2

-1 = + 1 - 2

-1 = -1

So , the solution to the equation is ( -1 , -1 )

And ,

y = 4x + 3

-1 = 4 ( -1 ) + 3

-1 = -4 + 3

-1 = -1

So , the solution to the equation is ( -1 , -1 )

Hence , the equations are y = - x - 2 and y = 4x + 3
