-8x+3=8x+27 I need help plz I’m trash at math
belka [17]

Answer:

-1.5

Step-by-step explanation:

<u>See steps below:</u>

  • -8x+3=8x+27
  • -8x + 3 - 8x - 3 = 8x+ 27 - 8x - 3          ⇒ add -8x - 3 to both sides in order to collect like terms in the different sides of equation
  • -16x = 24                                               ⇒ simplified
  • x= 24/-16                                               ⇒ divide
  • x= - 1.5                                                   ⇒ answer

Joshua uses his thermometer and finds the boiling point of ethyl alcohol to be 75 degrees Celsius. He looks in a reference book
MissTica

Answer:

6.25%

Step-by-step explanation:

Percent error is calculated by taking the difference of measured value and correct value divided by correct value and multiplied by 100%.

Mathematically,

Percent error = (correct value - measured value)/correct value  * 100%

_________________________________________________

in the problem given

measured value = 75 degrees Celsius

correct value = 80 degrees Celsius ( as given in reference book)

thus,

Percent error = (80 - 75)/80 * 100%

Percent error = (5/80 )* 100% = 6.25%

Percent error calculated by him is  6.25%.
