What is the value of x in the equation 4(2x + 14) = 0? a 9 b 7 c −7 d −9

Answers

Answer 1
Answer:

Answer:

x = -7

Step-by-step explanation:

4(2x + 14) = 0

Divide each side by 4

2x+14 = 0

Subtract 14 from each side

2x+14-14 = 0-14

2x= -14

Divide each side by 2

2x/2 = -14/2

x = -7
Answer 2
Answer:

Answer:

C, -7

Step-by-step explanation:

Use distributive property to get: 8x +56 = 0

Isolate x to get: 8x = -56

Then divide each side by 8: x= -7

The answer is C

Can you work this out: 14 x 14?

Answers

The product of the 14 x 14 is 196.

Given that we need to calculate 14 x 14,

To calculate 14 multiplied by 14, you simply multiply the two numbers together.

Here's the step-by-step process:

Start by multiplying the ones digit of the first number (4) by the ones digit of the second number (also 4).

4 x 4 = 16

Write down the ones digit of the result (6) and carry over the tens digit (1).

Next, multiply the tens digit of the first number (1) by the ones digit of the second number (4).

1 x 4 = 4

Add the carried over tens digit (1) to the result.

4 + 1 = 5

Write down the tens digit of the result (5) and carry over any remainingdigits (none in this case).

Finally, multiply the tens digit of the first number (1) by the tens digit of the second number (1).

1 x 1 = 1

Write down the tens digit of the result (1).

Putting it all together, we get:

14 x 14 = 196

Operation:

   14

×  14

------

  56   (4 × 14)

+140  (10 × 14)

------

 196

Therefore, 14 multiplied by 14 equals 196.

The bill for lunch was 24.50 mr smith add a 20% tip how much did mr smith pay

Answers

Answer:

Mr.Smith paid $29.4.

Step-by-step explanation:

Mr.Smith paid $24.5 plus additional 20% of $24.5, and to figure out the total amount that he paid, we need to know what is 20% of $24.50.

20% of $24.50 is:

(20)/(100)*24.5=0.2*24.6=4.9.

Mr.Smith paid additional $4.9; therefore, the total amount he paid was

$24.5 + $4.9 = $29.4.

Mr. smith paid $29.4.

The sum of three is 45. The second of the Three numbers is three more than twice the first number X. The third number is two more than the first number X. Which equation can be used to solve for the first number X

Answers

Answer:

see explanation

Step-by-step explanation:

the first number is x

the second number is 2x + 3

the third number is x + 2

sum the 3 numbers and equate to 45

the equation to solve for x is then

x + 2x + 3 + x + 2 = 45 ( simplify left side )

4x + 5 = 45 ( subtract 5 from both sides )

4x = 40 ( divide both sides by 4 )

x = 10

the first number is 10

To convert a measurement, Pete must move the decimal point to the left 4 places. This a shortcut for the operation. which operation is he using? Which power of 10 is involved?

Answers

The operation that Pete is using is the operation of multiplying numbers by decimal numbers and the power of 10 involved is 4

If Pete must move a decimal point to the left in 4 places, then the operation she is using is the operation of multiplying numbers by decimal numbers.

  • Since the movement is to the left in 4 places, the power of 10 involves will be a 4

For example,

  • if we are to convert 0.56 say to scientific notation to the power of 4. We will need to move the decimal point to the left 4 times to have 0.000056 * 10^4

Hence the operation that Pete is using is the operation of multiplying numbers by decimal numbers and the power of 10 involved is 4

The moving of decimal to the left is a shortcut to the operation of multiplying number by decimal numbers. So the power of 10 that is involved in converting the measurements of pete is -4, so he needs to multiply the measurement by 10^-4 to convert it.
