Answer:
20%=8
10%=?
by cross multiplications,
10×8=80
80÷20=4
Hence the answer is 4.
10, 20w, 2w, and we are factors of 20w and 40wz

- Mean Value Theorem (MVT) - If f is continuous on interval [a, b], then there is a c∈[a, b] such that

- MVT is also Average Value
Step-by-step explanation:
<u>Step 1: Define</u>

f'(c) = 20
Interval [1, b]
<u>Step 2: Check/Identify</u>
Function [1, b] is continuous.
Derivative [1, b] is continuous.
∴ There exists a c∈[1, b] such that 
<u>Step 3: Mean Value Theorem</u>
- Substitute:

- Rewrite:

And we have our final answer!
Answer:
value of x = 8
Step-by-step explanation:
if the given lines are parallel, then the shown pair of angles are corresponding angles,
and we know that the the pair of corresponding angles are equal so,
=》16x - 8 = 120
=》16x = 128
=》x = 128 ÷ 16
=》x = 8
4x + 7 <=== ur expression
