Someone help me please!

Mathematics
1 answer:
malfutka [58]3 years ago

Remember, all inside angles in a triangle add up to 180°

So:

3x+5x+7+x+2=180

Combine like terms

9x+9=180

Subtract 9 from both sides

180-9=171

9x=171

Divide by 9 on both sides

171/9=19

x=19

Plug it into all the angle measures.

Angle X: x+2, 9+2=11, Angle X=11°

Angle Y: 5x+7, 5(9)+7=52, Angle Y=52°

Angle Z: 3x, 3(9)=27, Angle Z=27°

What is the sign of the product (3)(-3)(-2)(4)? (5 points) Select one: a. Positive, because the products (3)(-3) and (-2)(4) are
Gnesinka [82]

Answer:  a. Positive, because the products (3)(-3) and (-2)(4) are negative, and the product of two negative numbers is positive

Step-by-step explanation:  It is also possible to rearrange the factors.

(3)(4) = 12  a positive number.

(-3)(-2) = 6, a positive number. Again "a negative times a negative is a positive"  --Jaime Escalante, <em>Stand and Deliver</em>

Now you have two positive numbers: 12×6 = 72

The product is positive either way.

Reduce to simplest form. - 3/5 + 1/3
Pani-rosa [81]

Answer: -4/15

Step-by-step explanation: To add these two fractions together,

we start by finding their <em>Least Common Denominator</em> (LCD).

Since our denominators of 5 and 3 have no factors in common,

our least common denominator is 5 · 3 or 15.

In order to get a denominator of 15 in each fraction,

we multiply top and bottom of the first fraction by 3

and top and bottom of the second fraction by 5.

That gives us -9/15 + 5/15 which simplifies to -4/15.

As your last step, make sure that the fraction

that you end up with doesn't reduce.

In this case, -4/15 does not reduce but watch out for this last step.

You pick a card at random, put it back, and then pick another card at random. 2 3 4 5 What is the probability of picking a numbe
olga_2 [115]

Answer:

3/4 or a 75% chance

Step-by-step explanation:

Out of 4 cards ( 2 3 4 5), here are the cards greater than 3: 4, and 5. That leaves you with a 2/4 chance of drawing one of them. (2 cards, 4 in total).

Then, picking a 4 out of 4 cards is a 1/4 chance; since that is one card out of 4 total possibilities.

1/4 + 2/4 = 3/4. Or, a 75% chance.
