Hey there! :)

Answer:

133 pieces.

Step-by-step explanation:

If 7 pieces of cardstock sell for $3, we can set up a proportion to determine the amount of pieces bought in pieces/ money spent:

$\frac{7}{3} = \frac{x}{57}$

Cross multiply:

7 · 57 = 3 · x

399 = 3x

Divide both sides by 3:

x = 133 pieces. This is the amount of pieces bought.

Mason plays a game by flipping two fair coins.He wins the game if both coins land facing heads up. If Mason plays 200 times, how

blagie [28]

Answer:

Therefore Mason would be expected to win 50 times.

Step-by-step explanation:

i) probability of flipping a head for a fair coin is $\frac{1}{2}$

ii) probability of flipping two fair coins is = $\frac{1}{2} \times \frac{1}{2} = \frac{1}{4}$

iii) Therefore if Mason plays 200 times he would be expected to win

= $\frac{1}{4} \times 200 = 50\hspace{0.1cm} times.$

Explain two ways you could solve 20 = 5(-3 + x)

MrRissso [65]

Answer:

The answer to your question is below

Step-by-step explanation:

First way

20 = 5(-3 + x) expand

20 = -15 + 5x simplify like terms

5x = 20 + 15

5x = 35 divide both sides by 5

5x/5 = 35/5

x = 7

Second way

20/5 = 5/5 (-3 + x) Divide both sides by 5

4 = -3 + x Add +3 in both sides

4 + 3 = -3 + 3 + x Simplify like terms

7 = x

1 + (-2/3) - (9/2) evaluate

Elina [12.6K]

Use the least common denominator(LCD) to solve this equation:

1 + (-2/3) - (9/2)

so, what is the LCM of 3 and 2 : 6

so, the LCD = 6

1 + (-2 x 2/6) - (9 x 3/6)

the 1 = 6/6

Put it back into the equation:

6/6 + (-4/6) - (27/6)

Then, take it out of the parenthesis:

6/6 - 4/6 - 27/6

Simplify:

= - 25/6

which is the answer.

Hope that helped !! Have a great day now
