Answer:
Step-by-step explanation:
You can do this using a small equation.
120% x = 96 Change 120% to a decimal
120/100 * x = 96 Multiply by 100
120x = 96 * 100
120x = 9600 Divide by 120
x = 9600/120
x = 80
Look what you got. 20% more than 80 is 96. x is smaller than 96.
If you take 20/100 * 80 = 16
if you add 16 to 80, you get 96
216. hope this helps you.
Answer:
16
Step-by-step explanation:
Use the method of PEMDAS (Parenthesis, Exponent, multiplication, division, addition and then subtraction.)
When using this order you would do 10-9 first
23 + 5 * (10-9) - 12
23+ 5 * 1 - 12
then 5 times 1
23 + 5 * 1 - 12
23 + 5 - 12
then 23 + 5 and subract 12 from the solution
23 + 5 - 12
28 - 12 =
16
Answer:
angle nol equals 67⁰
Step-by-step explanation:
since they make a straight line they both equal 180⁰ when added together
Answer:
ye^(2x) - 3e^(2x) = C or (y - 3)e^(2x) = C
Step-by-step explanation:
dy/dx + 2y = 6
This is a first order linear ODE.
p(x) = 2
Integrating factor: I(x) = e^(∫ 2 dx) = e^(2x)
e^(2x)(dy/dx + 2y) = 6e^(2x)
e^(2x) dy + 2ye^(2x) dx = 6e^(2x) dx
Integrate both sides of the equation.
ye^(2x) = 3e^(2x) + C
Thus, the general solution is ye^(2x) - 3e^(2x) = C or (y - 3)e^(2x) = C.
