Answer:
X = 30
Step-by-step explanation:
Because every triangle adds to the total of 180
so 102+48=150 and 180-150=30
Hope this helps
Answer:
either of Step 3 or Step 4
Step-by-step explanation:
At Step 3, -1 is added to both sides of the equation. Technically, this is correct (not an error), but it does not lead to a solution to the equation (so, could be considered to be an error). Adding +1 to both sides of the equation would lead more directly to a solution.
__
At Step 4, x -1 -1 is simplified to x. This is an error, as the correct simplification is x-2, so the equation after this step should read x-2 = 5. If Step 3 had been executed by adding +1 to both sides of the equation, then the simplification here would be x=7.

Answering "why" someone does something is always tricky. One can project one's own interpretation onto the actions of others, but one never really knows whether that is accurate or not.
The "why" in this case could go back to the motivation of the problem's author, which may be to see if the student can recognize that the opposite of -1 is +1, or that the sum -1-1 is not zero.
___
My guess is that Step 3 is considered to be the erroneous step, and that choosing Step 4 will get you into a losing argument with your grader.
Answer: salary is a form of payment from an employer to an employee, which may be specified in an employment contract and wages is monetary compensation (or remuneration, personnel expenses, labor) paid by an employer to an employee in exchange for work done.
Step-by-step explanation:
By seeing the proportion, we get that approximately, 870 g of rice is required and 130 g of meat is required for the recipe.
We are given that a recipe for two people requires 1kg of rice to 150 g of meat.
That is the proportion of rice to meat is:
1 kg : 150 g
1000 g : 150 g
100 : 15
20 : 3
Now, we are also given that 1 kg that is 1000 g of dish is to be prepared.
Let the portion of rice in it be x.
Portion of meat = 1000 - x
ATQ:
20 : 3 :: x : 1000 - x
20 / 3 = x / (1000 - x)
20,000 - 20 x = 3x
23 x = 20,000
x = 20000 / 23 = 870 ( approx.)
1000 - x = 1000 - 870 = 130.
Therefore, by seeing the proportion, we get that approximately, 870 g of rice is required and 130 g of meat is required for the recipe.
