Mama L [17]3 years ago

Answer:

since they are alternate exteriors, we put a equal sign

2x+78=5x+15

next we subtract 78 on both sides

2x+78-78=5x+15-78

2x=5x-63

then we subtract 5x on both sides

2x-5x=5x-5x-63

-3x=-63

after that we divide -3 on both sides

-3x/-3=-63/-3

and the answer is

x=21

The multiplication law is potentially helpful when we are interested in computing the probability of a. mutually exclusive event
Korvikt [17]

Answer:

b )  the intersection of two events

Step-by-step explanation:

Gary and Steve are both hosting . There are 50 buttons total, 15 buttons are blue and 27 buttons are red. Gary puts all of the buttons into a bag. Steve and Gary both want to wear red buttons.What is the probability ? To solve this problem, you need to understand the Multiplication Rule of Probability.This probability  means to find the probability of the intersection of two events, multiply the two probabilities.

Probability of two events occurring that is called intersection of two events. There are two different set of events , called independent and dependent events.

Independent events  event is not affected by a previous event.

A dependent event is when one event influences the outcome of another event . To find the intersection of two events, whether they are independent or dependent, multiply the two probabilities together.

How too simplify the problem 50÷5+3×4÷2-1​
Bumek [7]

To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

There are no parentheses or exponents in this expression, so to the next step (Multiplication/Division)  

Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right.

In this case that would be division first then multiplication.

NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression

50÷5+3×4÷2-1​

50 ÷ 5 = 10

10 + 3 × 4 ÷ 2 - 1

3 × 4 = 12

10 + 12 ÷ 2 - 1

12 ÷ 2 = 6

10 + 6 - 1

Addition/Subtraction

10 + 6 - 1

10 + 6 = 16

16 - 1

15

If BE=9cm, find GE<br> What is the answer
Sladkaya [172]

Answer:

GE = 3 cm

Step-by-step explanation:

BE = 9 cm

Since G is the centroid, therefore:

GE = \frac{1}{3}(BE) => Centroid theorem

Plug in the value

GE = \frac{1}{3}(9)

GE = 3 cm
