Answer:
x = 25
Step-by-step explanation:
Here's my work. Basically, I knew that the x in angle A is alternate interior to angle C, so they would both be x. the 50 degrees is one a 180 degree line, so the inside of the triangle DCB is 130. X must equal x, so they would both be 25 degrees.
The number of tablespoons of salt jacob mixes with 1 cup of water is 4 tablespoon of salt.
<h3>How to interpret the division? </h3>When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, divided in b equal parts.
Also, we can write:
(it is since )
The given table is:
Tablespoons of salt Cups of water
8 2
16 4
24 6
2 cups of water gets 8 tablespoon of salt.
Then 1 cup of water gets 8/2 = 4 tablespoons of salt. (divided the numbre of cups of water and number of tablespoons of salts in 2 equal parts).
This pattern remains same for other rows of the table, since we have:
1 cup of water gets 8/2 = 16/4 = 24/6 = 4 tablespoons of salt.
Thus, the number of tablespoons of salt jacob mixes with 1 cup of water is 4 tablespoon of salt.
