Y = 2x -7
x + 2y = 1

Answers

Answer 1
Answer: easy
y=2x-7
sub 2x-7 for every y you se inother equation
x+2(2x-7)=1
x+4x-14=1
5x-14=1
add 14 both sides
5x=15
divide 5
x=3

sub back

y=2x-7
y=2(3)-7
y=6-7
y=-1

(3,-1) is solution

The average attendance, A, at a minor league baseball park can be modeled by the equationA = 30w + 6,000
where w is the number of games the team won the previous year. What will the average attendance be next year if the team wins 61 games this year?

Answers

The average attendance for the next year if the team wins 61 games this year would be 7830.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have the average attendance [A] at a minor league baseball park that can be modeled by the equation -

A = 30w + 6000

where [w] is the number of games the team won the previous year.

The average attendance for the next year if the team wins 61 games this year would be at [w] = 61. So -

A[N] = 30 x 61 + 6000

A[N] = 1830 + 6000

A[N] = 7830

Therefore, the average attendance for the next year if the team wins 61 games this year would be 7830.

A box has 6 beads of the same size, but all are different colors. Tania draws a bead randomly from the box, notes its color, and then puts the bead back in the box. She repeats this 3 times. What is the probability that Tania would pick a yellow bead on the first draw, then a blue bead, and finally a yellow bead again?1 over 216

1 over 36

1 over 6

1 over 2

I;m thinking its 1/6 but I'm not sure

Answers

It is 1/6 because you only have 6 beads in total meaning that you have a one out of 6 chance of pulling out the yellow bead

Answer:

it is  1/216

Step-by-step explanation:

1/6x1/6x1/6=1/216

Bottom chunk is 4 by 4, so that part has 16 blocks. The next one up is 4 by 3 so that one is 12 blocks. Second from the top is 4 by 2, this chunk has 8 blocks. The very top chunk is 2 by 1, this one has only 2 blocks. 

1. Altogether there are 38 blocks. I added all the chunks together.

We can conclude that -

  • The percentage by which the selling price will decrease is 16%. The price will have to increase by 16% to return back to the original price.
  • The price will have to increase by 16% to return back to the original price.

What is Selling price?

The price at which a specific commodity is sold is known as the selling price.

Given is that the selling price of a house dropped from $250,000 to $210,000 over a period of 5 years.

A -

The percentage by which the selling price will decrease is -

%decrease = (250000 - 210000)/250000  x  100

%decrease = 40000/250000  x  100

%decrease = 4/25 x 100

%decrease = 4 x 4

%decrease = 16%

B -

The price will have to increase by 16% to return back to the original price.

Therefore, we can conclude that -

  • The percentage by which the selling price will decrease is 16%. The price will have to increase by 16% to return back to the original price.
  • The price will have to increase by 16% to return back to the original price.
