Answer: (5,3)

Step-by-step explanation:

Solve by Addition/Elimination

x + y = 8

3x − y = 12

Add the two equations together to eliminate y from the system.

    x + y = 8

+ 3x −y = 12

  4x      = 20

Divide each term in 4x = 20 by 4.

4x  = 20

4      4

Cancel the common factor of 4.

x= 20/4

x = 5

Substitute the value found for x into one of the original equations to solve for y.

  (5) + y = 8

Remove parentheses.

  5 + y = 8

Move all terms not containing y to the right side of the equation.

Subtract 5 from both sides of the equation.

  y = 8 − 5

Subtract 5 from 8.

  y = 3

The solution to the independent system of equations can be represented as a point.

  (5, 3)

The result can be shown in multiple forms.

Point Form:

  (5, 3)

Equation Form:

  x = 5, y = 3

Answer:

100.3 sqr. units

Step-by-step explanation:

Area of the composite figure = area of parallelogram + area of 2 semicircles

✔️Area of parallelogram = base * height

Base = 10

Height = 5

Area of parallelogram = 10*5 = 50 sqr. units

✔️Area of 2 semicircles = 2(½*πr²)

radius (r) = ½*8 = 4

Area of two semicircles = 2(½*π*4²)

Area of two semicircles = π*16 = 50.3 sqr.

✔️Area of composite figure = 50 + 50.3 = 100.3 sqr. units

Solution,

Here,

0.9 x 82

=73.8

Again, if we round it then it will be 74, so the estimate of 73.8 is 74.

The estimate product is 74. The actual product is 73.8. I hope this is what you're looking for!

Answer:

0.2364

Step-by-step explanation:

We will take

Lyme = L

HGE = H

P(L) = 16% = 0.16

P(H) = 10% = 0.10

P(L ∩ H) = 0.10 x p(L U H)

Using the addition theorem

P(L U H) = p(L) + P(H) - P(L ∩ H)

P(L U H) = 0.16 + 0.10 - 0.10 * p(L u H)

P(L U H) = 0.26 - 0.10p(L u H)

We collect like terms

P(L U H) + 0.10P(L U H) = 0.26

This can be rewritten as:

P(L U H)[1 +0.1] = 0.26

Then we have,

1.1p(L U H) = 0.26

We divide through by 1.1

P(L U H) = 0.26/1.1

= 0.2364

Therefore

P(L ∩ H) = 0.10 x 0.2364

The probability of tick also carrying lyme disease

P(L|H) = p(L ∩ H)/P(H)

= 0.1x0.2364/0.1

= 0.2364

Step-by-step explanation:

Answer:

A. 0.72

Step-by-step explanation:

We take the amount spent on the necklaces and divide that by the amount she bought. So that would be $11.52/8. When we divide this, we get 1.44, and since this is not an option, I went and divided it by the two friends to get 0.72. So I believe A. would be the answer.

The cost for each necklace is given as $0.72.

In order to calculate the cost of one item, divide the total cost of items by the total number of items.

It is also called the unit rate of that item.

Total money spent on 8 neckless is $11.52.

The number of friends Rosa has 2.

Then, total number of  necklaces is 8 × 2 = 16

Now, the cost of each necklace can be calculated as,

Total cost of necklace ÷ Number of necklace

= $11.52 ÷ 16

= $0.72

Hence, the cost of each necklace for each of the friends is $0.72.
