Simplify
34 + |18 = -9| × -5.

Answers

Answer 1

Answer:

Answer:

-11

Step-by-step explanation:

Calculate the absolute value of -9, which is 9.

Multiply 9 by -5, which equals -45.

Finally, add 34 to -45:

34 + (-45) = -11

So, the simplified expression is -11.

Answer 2

Answer: Answer:

= -101

step by step explanation:

Calculate the absolute value first:

|18 - (-9)| = |18 + 9| = |27| = 27

Now, we have:

34 + (27 × -5)

Perform the multiplication:

27 × -5 = -135

Finally, add 34 to -135:

34 - 135 = -101

So, the simplified expression is -101

I hope this will help too.

Who invented division?

Answers

the ancient egyptians

John Napier is said to have invented the mathematical function know as division. His calculation were further developed by Henry Briggs.

The work of a student to solve a set of equations is shown:Equation A: y = 4 − 2z
Equation B: 4y = 2 − 4z

Step 1: −4(y) = −4(4 − 2z) [Equation A is multiplied by −4.]
4y = 2 − 4z [Equation B]
Step 2: −4y = 4 − 2z [Equation A in Step 1 is simplified.]
4y = 2 − 4z [Equation B]
Step 3: 0 = 6 − 6z [Equations in Step 2 are added.]
Step 4: 6z = 6
Step 5: z = 1

In which step did the student first make an error?
Step 1
Step 3
Step 4
Step 2

Answers

The student first made an error in step 2 when she simplified... She should have used the distributive property to distribute the -4 through the parentheses. It should look like this...

-4 (y) = -4 (4 - 2z)
-4y = -16 + 8z

What is the algebraic expression for the quotient of 17 and K?

Answers

The algebraic expression for the quotient of 17 & k can be written by knowing which one is the divisor and which one is the dividend. Because 17 comes before the "and", it would be the dividend, and because k comes after the "and", it would be the divisor. So, your expression should look like this:

17/k

Final answer:

The algebraic expression for the quotient of 17 and K is 17/K.

Explanation:

The algebraic expression for the quotient of 17 and K is 17/K. In algebra, division is represented by the forward slash symbol (/). So, when you divide 17 by a variable K, the quotient is expressed as 17/K.
