#3 Q. the diagrams solve please
olya-2409 [2.1K]
Its the first one, 22.5. This is because... if you multiply 5 and 4, you would get 20, the area of the square. You then have to multiply 1 and 5 to get 5 and divide it by 2 to get the area of the triangle which would be 2.5, then add 2.5 to 20 and get 22.5.
Hope this helps :)

What are the solutions to the system of equations,<br> y=x+21<br> 2x+y=57
kondaur [170]

Answer:

(12,33)

Step-by-step explanation:

This system can be solved using the substitution method. This is where you replace one variable by another.

Step 1:

Plug in x+21 for the y

Step 2:

Combine like terms

2x+x+21=57\\3x+21=57

Step 3:

Subtract 21 from both sides

3x=36

Step 4:

Divide both sides by 3

x=12

Step 5:

Use the first equation and plug in 12 for x

y=12+21

y=33

Step 6:

Proof of work

2(12)+33=57\\24+33=57\\57=57

Maurinko [17]

Answer:

Pre-Hispanic Philippine literature was actually epics passed on from generation to generation, originally through an oral tradition. However, wealthy families, especially in Mindanao, were able to keep transcribed copies of these epics as family heirloom. One such was the Darangen, an epic of the Maranaos.
