What is the answer to the equation? Explain how you would solve this problem. 2x - 8 = 50

Answers

Answer 1
Answer: The answer is 29. The answer is 29 because you add the 8 to 50. You get 58. Then divide 58 by 2 and you get 29.
Answer 2
Answer:

Answer:

x=29

Step-by-step explanation:

2x - 8 = 50

Here we need the value of x. so first we will  remove -8 by adding 8 on both side.

=>2x =50+8       [add 8 on both side]

=>2x=58

then we get 2x . so, we will divide both side by 2.

=>x=58/2

=>x=29

on a number line, between which two consecutive whole numbers would the square root of 70 be located? prove work/show work

Answers

Square root of 64 is 8.

Square root of 81 is 9.



So, the square root of 70 has to lie in between the two consecutive numbers 8 and 9.

Square root of 70 will be closer to 8 than it will be to 9, however.

True or false?

Answers

True, Fe (iron) has 2 on the left side and on the other side as well. C (carbon) has 3 on the left and 3 on the other. O (oxygen) has 6, 3 for the first part and another 3 because of the reciprocal in the beginning of the equation. On the other side O has 2 and it's multiplied by the reciprocal 3 which is 6

Solve 81x = 27x + 2.

x = 1
x = 2
x = 5
x = 6

Answers

81x = 27x + 2
81x - 27x  =  2
54x = 2
x = 2/54
x  = 1/27

none of the above is the answer...

Answer: x = 6

Step-by-step explanation:

Let's solve your equation step-by-step.

81x=27x+2

Solve Exponent.

81x=27x+2

log(81x)=log(27x+2)(Take log of both sides)

x*(log(81))=(x+2)*(log(27))

x=(

log(27)

log(81)

)*(x+2)

x=0.75*(x+2)

x=0.75x+1.5(Simplify both sides of the equation)

x−0.75x=0.75x+1.5−0.75x(Subtract 0.75x from both sides)

0.25x=1.5

0.25x

0.25

=

1.5

0.25

(Divide both sides by 0.25)

x=6

60%is less than 65%

The height of a man is 1.7 meters.what is his height in centimeters

Answers

If the  height of a man is 1.7 meters then the height in centimeters is 170 centimeters.

To convert meters to centimeters, we multiply the length in meters by 100 since there are 100 centimeters in 1 meter.

Given that the man's height is 1.7 meters, we can multiply this value by 100 to obtain the equivalent height in centimeters:

1.7 meters × 100 centimeters per meter

= 170 centimeters

Therefore, the man's height is 170 centimeters.

His height in centimeters is 170 cm

Further Explanation

Given:

Height is 1.7 meters (m). What is his height in centimeters?

We are going to convert meters (m) to centimeters (cm)

=\boxed {1 m = 100cm\ }

so to convert 1.7m to cm, just multiply it with 100 cm

=\boxed {1.7 m *100 cm\ }\n =\boxed {170cm\ }

there is another way to do it, in three step:

  • write the conversion in fraction
  • multiply
  • cancel any units that are both top and bottom

(100 cm)/(1m) = 1

=\boxed {1.7m *(100cm)/(1m)\ }\n =\boxed {(1.7m *\ 100 cm)/(1 m)\ }\n =\boxed {170 cm\ }

We can cancel the meter (m) because it is both on top and the bottom
