Courtney and Chelsea are leading a family hike on Saturday. The number of snacks Chelsea is bringing can be represented by 2x. C

myrzilka [38]

Answer:

Courtney is bringing 8 snacks

Step-by-step explanation:

Chelsea's snacks are represented as 2x.

2x means 2 · (a number)

If Chelsea brought 16 snacks and the amount of snacks represented by 2x, we have to figure out what times 2 equals 16.

In order to find out, we have to divide.

16 ÷ 8 = 2

This means 2 · 8 = 16

Since the amount of snacks Courtney brings is represented as "x", she would have brought 8 snacks.

Hope this helped! :)

A roofer leaned a 16-foot ladder against a house. If the base of the ladder is 5 feet from the house, how high up the house does

elixir [45]

Answer:

15.20feet

Step-by-step explanation:

Length of the ladder = 16foot (hypotenuse)

BAse of the ladder from the house = 5feet (adjacent)

height of the house = x (opposite)

Using the pythagoras theorem

hyp^2 = opp^2 + adj^2

16^2 = 5^2 + opp^2

256 = 25 + opp^2

opp^2 = 256-25

opp^2 = 231

opp =√231

opp = 15.20

Hence the house is 15.20feet high up the house

Which is a equivalent to 80 1/4x

elena55 [62]

Since you did not provide options for what 80 $\frac{1}{4}$ x could be equivalent to,, it is near to impossible to answer this question fully. I will simplify 80 $\frac{1}{4}$ x for you and then when you can provide the options for me,, I could help you find the answer if you need it.
To simplify this you must reduce the numbers with 4 in order to find your final answer.
20x.
This means that the correct answer to your question is 20x.
Let me know if you have any further questions.
