2x=4 and 3x=6
So, think of a number that you can substitute for x in this equation that when you multiply it to 2 and 3, will arrive with the answer which is 4, and 6 respectively.
In this case, the correct number will be 2.
Wherein:
2(2)=4
3(2)=6

The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 18
kogti [31]

Answer: One side could be 18 and the other side will be 33.

Step-by-step explanation:

  • Side #1 = 18
  • Side #2 = 2x - 3
  • Side #3 = x

<u>One way of setting up the inequality is: Side #2 + Side #3 > Side #1</u>

<u />2x-3+x>18\\3x-3>18\\3x>18+3\\3x>21\\x>7

<u>Another way of setting up the inequality is: Side #1 + Side #3 > Side #2</u>

<u />18+x>2x-3\\18+3>2x-x\\x<u />

<u>Final way of setting up the inequality is: Side #1 + Side #2 > Side #3</u>

<u />18+2x-3>x\\15>x-2x\\15>-x\\x>-15<em />

<em>Therefore, we have the range for our value of x, which is between 7 and 21. Any possible value between works. Negative measurements are rejected. One of the sides would equal the x-value, while the other side would equal the value of 2x-3.</em>

Solve for the base. Round to hundredths when necessary.
Elena-2011 [213]

Answer:

  1. 2730.54
  2. 18.8%
  3. 62.5% (decrease)

Step-by-step explanation:

The applicable formula is ...

  rate = portion/base

so ...

  base = portion/rate

Of course, a percentage is a fraction that has been multiplied by 100%.

__

1. base = portion/rate = 456/0.167 ≈ 2730.54

The base is about 2730.54.

__

2. rate = portion/base = 50/266 ≈ 0.18797 ≈ 18.8%

The rate is about 18.8%.

__

3. The decrease can be figured from ...

  rate of change = (new amount)/(original) -1 = 33/88 -1

     = -5/8 = -0.625 = -62.5%

The rate of decrease is 62.5%.

How do you work out this question
Likurg_2 [28]

Answer:

The original price is $7926.83

Step-by-step explanation:

Step 1: Subtract the percent of the discount from the percent of the original cost:

100% - 18% = 82%

Step 2: Convert the percent to a decimal.

82% = 0.82

Step 3: Solve for the original price.

\frac{0.82x}{0.82} = \frac{6500}{0.82}

= 7926.829268 (Round to the nearest tenths)

$7926.83

Hope it helps!!!
