Definitely B. Note how the powers of y are presented in descending order by power: y^8, y^7, y^1.
Answer:
Option (c) is correct.
Step-by-step explanation:
Given equation is :

The equation can be solved for a as follows :
Step 1.
Cross multiply the given equation

Step 2.
Now subtract b on both sides
3s-b = a+b+c-b
3s-b = a+c
Step 3.
Subtract c on both sides
3s-b-c=a+c-c
⇒ a=3s-b-c
The statement that is true for Darpana is " In step 3, she needed to subtract c rather than divide".
Answer:
D, E, F
Step-by-step explanation:
The first step I would do is distribute the original equation. After distributing, the equation is now 8x² + 16xy. The first answer I see that matches this is D.
Then, after already eliminating A, B, and C, I look at E. I distribute the x and find out it is also equal to 8x² + 16xy.
Then, I look at F. After distributing again, it is also equal to 8x² + 16xy.
Answer:
$24
Step-by-step explanation:
a= $30-$12 = 6 cup of coffee
= 18÷6
= 3 (price for a cup of coffee)
= 3×2
= $6
a= $30-$6
a= $24
