Step-by-step explanation:
<u>Step 1: Define</u>
Ax + bx = c
<u>Step 1: Solve for </u><em><u>x</u></em>
- Factor: x(A + b) = c
- Isolate <em>x</em>: x = c/(A + b)
We know that we cannot divide by 0, so A + b cannot equal 0.
<em>Here, I'll show you simple steps.
As we know, Percentage=(value</em>×<em>100)/total value
</em><em>So, to get reversed the main value from given percentage and total value.
</em>
<em></em>∴Value×100=Percentage×total value
∴Value = (Percentage×total value)/100
1/2 bh= area of triangle
S*2= perimeter of rectangle
LW=area of square
4s= perimeter of square
2l+2w= area for rectangle
A + b+ c= perimeter of triangle
Hope this helps *smiles*
Sorry if it’s wrong
Number 1 Right
Number 2: Since it's an absolute value you'll have 2 solutions:
I x+2 I = 5 ===> x = -3
& - I x+2 I = 5 ==> ===> x =7
Number 3: I r-7 I < = 5, r < = 12 & -I r-7 I < = 5 , = -r+7 < = 5 or r> = 12
& so on & so forth. Never forget that an absolute value may have 2 answers, the first one you take the positive value of the equation & the 2nd one you take the negative value & you solve
