Answer:
t = -1
Step-by-step explanation:
8 + 9t - 3 + 4
Combine like terms
(8 - 3 + 4) + 9t
9 + 9t
9t + 9
Get <em>t</em> by itself
9t + 9 = 0
-9 -9
9t = -9
Divide both sides by 9 to find <em>t</em>
t = -1
Answer:
d=1/2
Step-by-step explanation:
9(8d-5)+13=12d-2
1) Use the distributive property:
72d-45+13=12d-2
2) Combine alike terms:
72d-32=12d-2
3) Add 32 to both sides:
72d=12d+30
4) Subtract 12d on both sides:
60d=30
5) Divide both sides by 60:
d=30/60
6) Simplify 30/60 to 1/2
===================================
- A body of mass 10kg at rest is subjected force of 16N. Find the kinetic energy at end of 20s.
===================================
===================================
<em>Firstly</em>, find the acceleration:
<em>Secondly,</em> the velocity after 20 seconds will be:
<em>Lastly</em>, find the kinetic energy:
Hence, the kinetic energy at the end is 5,120 Joules.

I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)
First I did what’s inside the parentheses, (6x2) and got 12.
Then I divided 16 by 22 and received 0.72.
I added 0.72 with 12 and the result was 12.72.
Last step was to subtract 12.72 - 8 and that equals 4.72
For every 100 students 20% is 20 students so 20 students participate in after school clubs. Because 20% of 100 is 20 just like 50% is 50 students.
