How to calculate a common fraction​

Answers

Answer 1

To find a common denominator, multiply each part of a fraction by the denominator of the other fraction. For example, to find a common denominator for 1/3 + 2/5, multiply the 1 and 3 by 5 and multiply the 2 and 5 by 3. You should get 5/15 + 6/15. Then you can calculate the fractions.

Answer and Step-by-step explanation:

8. We want to solve for a of the trapezoid area formula.

A = [tex]\frac{h}{2} (a + b)[/tex]

First off, we need to multiply both sides by [tex]\frac{2}{h}[/tex] to cancel out the [tex]\frac{h}{2}[/tex].

[tex]\frac{2A}{h}[/tex] = a + b

Now, we need to subtract b from both sides.

[tex]\frac{2A - b}{h}[/tex] = a

We get the answer to be:

I. a = [tex]\frac{2A - b}{h}[/tex]

Can somebody help me with this pleaseee!!! Help will be very appreciated And may you explain why it’s a lie .

Answers

Answer:

my mother say it is B. she is good at math

Answer: A

Step-by-step explanation:

Answer A is a lie. The most obvious reason being the other two statements can be proven because the y intercept of the exponential IS (0, 1). Secondly, the point (-2, 4) CAN be found on the graph. Option A is the lie because if you look, for x = 10, y = 0. Therefore, the statement that for very large values of x the exponential has very large values of y, is a lie.

Answers

Answer: 64

Step-by-step explanation:

The total possible outcomes will be 312.

Possible outcomes:

"A list of resulting possibilities from an event".

How to find possible outcome?

To find the total number of outcomes for two or more events, multiply the number of outcomes for each event together.

According to the given question

A card is chosen from a standard deck and a die is rolled.

Therefore,

A deck of 52 cards have 52 different possibilities .

A six sided die has 6 possibilities.

According to the question:

possible outcomes[tex]=6[/tex]×[tex]52[/tex][tex]=312[/tex]

Answers

Answer: x =67

Step-by-step explanation:

The equation to solve this is (x - 22) + 135 = 180

1) To solve for x, you must remove the parenthesis

x - 22 + 135 = 180

2) Simplify the equation...

x - 113 = 180

3) Simplify the equation

180-113 = x

3) Subtract to solve

180 - 113 = x

x = 67

Answer :

As shown in the figure the angles x - 22 and 135 lie on a straight line . So we may solve it using linear pair property that states that the sum of angles lying on a straight line is 180° .

( x - 22 ) + 135 = 180°Remove the brackets

x - 22 + 135 = 180Subtract 22 from 135 and as 135 is is greater than 22 the sign will be positive

x + 113 = 180Subtract 113 from both the sides

x = 180 - 113x = 67°

Thus the correct answer is option d that is x = 67
