Step-by-step explanation:
Answer: x = -30
Step-by-step explanation:
y = -20 by using process of elimination substitute y as -20 in either of the equations you get -30 for x
Length = 2W
P= 2L + 2W
60 = 2(2W) + 2W
60= 4W +2W
60 = 6W
60/6W = 6W/6W
w = 10
Length = 2(10)
Length = 20
P= 2L + 2W
60= 2(20) + 2(10)
60= 40 +20
60 = 60
Using the probability concept, it is found that there is a 0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In an experimental probability, these number of outcomes are taken from previous trials.
In this problem:
- The experiment was made 20 times.
- Of those, in 6 experiments(81, 105, 171, 159, 297, 387) she choose a page that was divisible by 3.
Then:

0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.

Answer:
cups of butter should be use to keep the same ratio.
Step-by-step explanation:
Given:
A recipe for pie dough calls for a ratio of butter to flour of 1/4 :5/6.
If you plan to use 5 cups of flour.
Now, to find the butter should be used to keep the same ratio.
So, to get the quantity of butter by using unitary method:
If,
cup of flour use then butter should be =
.
So, 1 cup of flour use then butter should be =
=
.
Thus, for 5 cups of flour butter should be =
=
.
Therefore,
cups of butter should be use to keep the same ratio.
