Answer: Original expression: 2x - 11 + 4x + 7 + 3(x-4)

Simplified: 9x - 16

Step-by-step explanation:

2x - 11 + 4x + 7 + 3(x-4) becomes 2x - 11 + 4x + 7 + 3x -12

Group like terms, then combine to simplify:

2x + 4x + 3x -11 + 7 - 12

2x + 4x + 3x = 9x

-11 -12 + 7 = =23+7= -16

Simplified expression: 9x - 16

Convert 25 1/3% to decimal. Round to the nearest thousandth if necessary.

Anni [7]

Decimal: 25.3333, but converted properly it is
.253333....(repeating) so to the nearest thousands it would be .253

What is the power of 10 when 0.000028 is written in scientific notation

mezya [45]

-5 as that you would have to count that places to the left. You end decimal would have to be between 1 and 10, so it would not count the 8. I'm sorry if my explanation is not good, but that is the right answer

Emily has 7 cups of water in a jug.If she drinks 2/3 of a cup every hour.How long would it take her to drink the whole jug

zepelin [54]

It would take her 10.5 hours to drink the whole jug.

Step-by-step explanation:

Given,

Cups of water in jug = 7

Water drunk every hour = $\frac{2}{3}$ of cup

Let,

x be the number of hours.

According to given statement;

$\frac{2}{3}x=7$

Multiplying both sides by $\frac{3}{2}$

$\frac{3}{2}*\frac{2}{3}x=7*\frac{3}{2}\\x=\frac{21}{2}\\x=10.5$

It would take her 10.5 hours to drink the whole jug.
