Answer:
x = e^12/100
Step-by-step explanation:
Solve for x over the real numbers:
10 ln(100 x) - 3 = 117
Add 3 to both sides:
10 ln(100 x) = 120
Divide both sides by 10:
ln(100 x) = 12
Cancel logarithms by taking exp of both sides:
100 x = e^12
Divide both sides by 100:
Answer: x = e^12/100
Are you asking to find the perimeter of the polygons?
Answer:
20:25
Step-by-step explanation:
add how many parts (4+5=9)
45/9=5
4*5=20, 5*5=25
therefore, 20:25
Answer:
The length of the two pieces are 41 in and 24 in
Step-by-step explanation:
Let
x -----> the length of one piece
y ----> the length of the other piece
we know that
-----> equation A
-----> equation B
Solve the system of equations by substitution
Substitute equation B in equation A and solve for y
Find the value of x
therefore
The length of the two pieces are 41 in and 24 in
Conversion a mixed number 2 2

To find new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3
3
= 6

b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8
c) Write previous answer (new numerator 8) over the denominator 3.
Two and two thirds is eight thirds
Divide: 5

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 8
3
is 3
8
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - five eighths divided by eight thirds = fifteen sixty-fourths.
