tankabanditka [31]3 years ago
4 0

Answer:

4

Step-by-step explanation:

Set up ratios of corresponding sides.  x+2 is to 6 as 2 is to 3:

\frac{x+2}{6}=\frac{2}{3}

Now cross multiply to get

3(x + 2) = 12 and

3x + 6 = 12 so

3x = 6 and

x = 2.  That means that side AB, x + 2, is 2 + 2 which is 4

mario62 [17]

Answer:

About 163 388 employees

Step-by-step explanation:

Let total number of employees in the company be represented by x. Thus:

18.3\% \: of \: x = 29900

18.3\% \:x \:  = 29900

\frac{18.3}{100}x = 29900

0.183x = 29900

Divide through by 0.183

\frac{0.183x}{0.183}  =  \frac{29900}{0.183}

x = 163387.9

x = 163388 \: to \: nearest \: whole \: number

The total number of employees in one country is about 163388

Carmen bought a desktop computer and a laptop computer. Before finance charges, the laptop cost $200 less than the desktop. She
stiks02 [169]
Let x = cost of desktop computer; then x - 250 = cost of laptop computer

converting % to decimals, 9% = 0.09 and 6% = 0.06

Then, 0.09x + (x - 250)0.06 = $300
0.09x + 0.06x - 15 = $300
0.15x = $315
x = $2100
then x - 250 = $1850

Proof: $2100•0.09 + 1850•0.06 = $189 + $111 = $300

A store orders 22 boxes of light bulbs. Each box has 148 bulbs.
Schach [20]

Answer:

3,256bulbs

Step-by-step explanation:

From the question, we can see that;

Total number of boxes ordered = 22boxes

If each box contains 148 bulbs, then;

1 box = 148bulbs

To get the total bulbs we have we will say;

22boxes = x bulbs

solve this two expressions for x:

1box = 148bulbs

22boxes = x bulbs

Cross multiply

1×x = 22×148

x = 3256bulbs

Hence the best estimate of the total number of bulbs the store orders is 3,256bulbs
