Answer:

The correct option is (A)

Step-by-step explanation:

First add (12x + 9y) + (-2y).

After opening the brackets \left (+\times-  \right ) is - we get;

12x + 9y - 2y

Subtract like terms 9y - 2y, we get;

12x + 7y

Now subtract (4x - 3y) from (12x + 7y). Write the equation as follows:

(12x + 7y) - (4x - 3y)

Open the brackets \left (-\times-  \right ) is +

12x + 7y - 4x + 3y

Put like terms together:

= 12x - 4x + 7y + 3y

= 8x + 10y

Therefore, correct option is (A)

(12x + 9y) + (-2y) - (4x - 3y)

= 12x + 9y - 2y - 4x + 3y

= 12x - 4x + 9y - 2y + 3y

= 8x + 10y

A) 8x + 10y

A local high school has both male and female students.
Kitty [74]

Answer:

a. P(male) = 0.4

b. P(no sport and male) = 0.1

c. Unclear question (isn't it the same as b.?)

Step-by-step explanation:

The data below is what I've worked according to, which isn't very clear from the question so the answers are only correct if this is the correct table of data;

\left[\begin{array}{ccc}&No \ Sports&Sports\\Female&10&32\\Male&7&21\end {array}\right]

a.

P(male) = \frac{7 + 21}{70} \\\\ = \frac{28}{70} \\\\ = \frac{2}{5}

b.

Using the tree diagram in the picture;

P(no \ sport \ and \ male) = \frac{2}{5} * \frac{1}{4} \\\\ = \frac{1}{10}

The winner of a 100 mile race drove his car to victory at a rate of 120.1229 mph. What was his time to the nearest thousandth of
Zigmanuir [339]

Answer:

t=1.201\ \text{hour}

Step-by-step explanation:

Given that,

Distance, d = 100 mile

Velocity of the winner, v = 120.1229 mph

We know that velocity of an object is equal to distance per unit time. Let t is the time. So,

v=\dfrac{d}{t}\\\\t=\dfrac{d}{v}\\\\t=\dfrac{120.1229}{100 }\\\\t=1.201229\ \text{hour}\\\\\text{Round to the nearest thousandth}\\\\t=1.201\ \text{hour}

Hence, 1.201 hour is taken by the winner.
