Answer:

see explanation

Step-by-step explanation:

ΔABE and ΔACD are similar hence the ratios of corresponding sides are equal, that is

\frac{AB}{AC} = \frac{AE}{ED} = \frac{BE}{CD}

Using the first pair of ratios then

\frac{20}{5} = 4 = \frac{26}{ED}, hence

4ED = 26 ( divide both sides by 4 )

ED = 6.5 cm

------------------------------------------------------------------

(b)

Similarly

\frac{BE}{18} = 4, hence

BE = 4 × 18 = 72 cm

Ben is making salsa.He needs 1/3 cups of chilies for each bach of salsa.Ben has 5/6 cup green chilies.How many baches of salsa c
FromTheMoon [43]

Answer:

The number of batches Ben can make with 5/6 cup of green chilies is 2\frac{1}{2} batches of salsa.

Step-by-step explanation:

From the question,

Ben needs 1/3 cups of chilies for a batch of salsa.

To determine how many batches of salsa he can make with 5/6 cup of green chilies,

Let the number of batches Ben can make with 5/6 cup of green chilies be x.

Now,

If 1/3 cups of green chilies is needed for 1 batch,

Then, 5/6 cups of green chilies will make x batches

1/3 × x = 5/6 × 1

x = 5/6 ÷ 1/3

x = \frac{5}{6} \div \frac{1}{3}

x = \frac{5}{6} \times \frac{3}{1}

x = \frac{15}{6}

x = \frac{5}{2}

x = 2\frac{1}{2}

Hence, the number of batches Ben can make with 5/6 cup of green chilies is 2\frac{1}{2} batches of salsa.

~~~~~~\dfrac{2x-3}{4} = 3x\\\\\implies 2x-3 = (3x)(4)\\\\\implies 2x -3 = 12x \\\\\implies 12x -2x = -3\\\\\implies 10x = -3\\\\\implies x = -\dfrac{3}{10}
