Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

(-4/13)+(5/26)

So,now take the common denominator by taking least common multiple (LCM)..

LCM=26

= {(-4/13)x26} + {(5/26)x26}

= (-8+5)/26

= -3/26

You can divide both numerator and denominator by 20 because its the LCD of both numbers if you needed to show proof. :)

Jay and Blair went fishing together they caught 27 fish. Jay caught 2 times as many fish as Blair. How many fish did Jay and Blair each catch? write an equation and solve. Explain your work

Answers

Blair caught 9 fish, and Jay caught 18 fish out of 27 fish. By using the two equations.

Let's assume the number of fish Blair caught is represented by the variable "B". Since Jay caught 2 times as many fish as Blair, the number of fish Jay caught can be represented by the variable "J" as 2B.

According to the given information, Jay and Blair caught a total of 27 fish. We can write this as an equation:

B + J = 27

Substituting the values for J and B in terms of each other:

B + 2B = 27

Combining like terms:

3B = 27

Now, we can solve the equation for B by dividing both sides by 3:

B = 27 / 3

B = 9

So, Blair caught 9 fish.

To find the number of fish Jay caught, we substitute the value of B back into the equation:

J = 2B

J = 2(9)

J = 18

Therefore, Jay caught 18 fish. In conclusion, Blair caught 9 fish, and Jay caught 18 fish.

The quadrilateral shown is a rectangle. What is m∠MJN?

A) 24° B) 31° C) 66° D) 90°

Answers

All angles of a rectangle is right angled or 90°.

C) 66°

Given:

∠KJN= 24°

Diagonals in a Rectangle:

The diagonals bisect each other but do not form right angles at the center.
They form linear pairs of angles, obtuse angle + acute angle, as at each of the diagonal.

Thus,

∠MJN+∠KJN=90°

∠MJN = (90-24)°

∠MJN = 66°

Therefore, correct option is C.

Find more information about diagonals here:

Step-by-step explanation:

all the angles of the rectangle are right angle

therefore, angle MJK=90°

∠MJN+∠KJN=90°

∠MJN = (90-24)° = 66°
