What is 2/3(n+6)=10?<br> What is n?<br> 2/3 is a fraction as two thirds
Aleks04 [339]
First distribute the 2/3.
(2/3)n + (2/3)*6 = 10
(2/3)n + 4 = 10
Subtract 4 from both sides
(2/3)n = 6
Multiply both sides by (3/2) to clear the fraction
n = 9

Answer:

  • trailing zeros are dropped
  • 1846 beats
  • 42×(selling price for 1 tin)

Step-by-step explanation:

41. The product of 0.25 and 0.4 is 0.100, with three decimal places. Trailing zeros are usually dropped--except when they are used to indicate significant digits in a calculation. Hence, the usual presentation of the result is ...

  0.25 × 0.4 = 0.1

__

42. To find total beats, multiply beats per second by seconds.

  (52 beats/second)(35.5 seconds) = (52)(35.5) beats = 1846 beats

The hummingbird's wings will beat 1846 times in 35.5 seconds.

__

43. To find total sales for the week, multiply the price of a tin of popcorn by the number sold in the week (42).
