B226.
C.32
D.18
What value of x makes the equation below true? 7x-1=9
A.2/7
B.8/7
C.10/7
D.16/7

Answers

Answer 1
Answer: 16^2
16*16
256
A

7x-1=9
7x-1+1 = 9+1
7x=10
(7x)/(7) = (10)/(7)
x= (7)/(10)
C
Answer 2
Answer: 1) I think you meant 16^2. That's 4^4, so it would be 64*4 which is 256, A
2) 7x-1 = 9
7x=10
x=10/7
C

Marcia says she can use rounding to find the exact product of 6x75. She says that since 75 is halfway between 7 tens and 8 tens the exact product of 6x75 must be halfway between 6x70 and 6x80 is she correct

Answers

Marcia is correct if she says she can use rounding to find the exact product of 6x75; the exact product of 6x75 must be halfway between 6x70 and 6x80.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

Marcia says she can use rounding to find the exact product of 6x75.

From the data:

Find the product of 6 and 75:

= 6x75

= 450

Find the product of 6 and 70:

= 6x70

= 420

Find the product of 6 and 80:

= 6x80

= 480

= 420 + 30

=450

= 450 + 30

= 480

The expression can be defined as the combination of constants and variables with mathematical operators.

Thus, Marcia is correct if she says she can use rounding to find the exact product of 6x75; the exact product of 6x75 must be halfway between 6x70 and 6x80.

Yes because 6x75=450
6x70=420
6x80=480

So 420+30=450
450+30=480

Apply the distributive property to factor out the greatest common factor. 22c+33d

Answers

Answer: Our required answer is 11(2c+3d)

Step-by-step explanation:

Since we have given that

22c + 33d.

We have to use "Distributive property" to factor out the greatest common factor.

Since we know that 11 is the greatest common factor of 22 and 33.

So, it becomes,

11(2c+3d)

Hence, our required answer is 11(2c+3d)

Answer:

11 (2c+3d)

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:

brainly.com/question/198970

Step-by-step explanation:

all the angles of the rectangle are right angle

therefore, angle MJK=90°

∠MJN+∠KJN=90°

∠MJN = (90-24)° = 66°
