Step-by-step explanation:
<u>Step 1: Define</u>
3n - 8 = 32 - n
<u>Step 2: Solve for </u><em><u>n</u></em>
- Add <em>n</em> on both sides: 4n - 8 = 32
- Add 8 on both sides: 4n = 40
- Divide 4 on both sides: n = 10
<u>Step 3: Check</u>
<em>Plug in n into the original equation to verify it's a solution.</em>
- Substitute in <em>n</em>: 3(10) - 8 = 32 - 10
- Multiply: 30 - 8 = 32 - 10
- Subtract: 22 = 22
Here we see that 22 does indeed equal 22.
∴ n = 10 is the solution to the equation.
Answer:
a=100 b=50 c=30
Step-by-step explanation:
30+50+a= 180, A= 100.
90+40+b=180, B=50
A+B+C= 180
100+50+c=180, C=30

So, we should know that 1/3 hours equals to about 20 minutes, and in 20 minutes, he reads 11 pages so 20*3= 11*3 so that will be 60 minutes= 33 pages so that will be Leo reading 33 pages per hour. Hope this helps!
