Answer:
Step-by-step explanation:
1. A right angle has a measure of 90°. The whole is the sum of the parts.
(2x +3)° +49° = 90°
2x +52 = 90 . . . . . . . . divide by °, collect terms
2x = 38 . . . . . . . . . . . . subtract 52
x = 19 . . . . . . . . divide by 2
__
2. A linear pair measures 180°. The whole is the sum of the parts.
(x -5)° +151° = 180°
x +146 = 180 . . . . . . . divide by °, collect terms
x = 34 . . . . . . . . .subtract 146
__
3. We presume this pair of angles is supposed to be supplementary. That is, their sum is 180°.
64° +(3x -1)° = 180°
3x +63 = 180 . . . . . . . divide by °, collect terms
3x = 117 . . . . . . . . subtract 63
x = 39 . . . . . divide by 3

A proportion
is nothing but a comparison between two fractions: we can rewrite it as
So, we can multiply both sides by the two denominators b and d to get
In other words, a proportion is true if the product of the inner terms is the same as the product of the outer terms.
In your case, we have the check is the following:
which is clearly false. So, 24:40 = 4:7 is not a true proportion. In fact, if we convert fractions into numbers, we have
which makes even more clear that the proportion doesn't hold.
Answer:
3 ln 4 + 3 lna
Step-by-step explanation:
In (4a)^3
We know that ln x^y = y ln x
3 ln (4a)
We also know that ln (xy) = ln x + ln y
3( ln 4 + ln a)
3 ln 4 + 3 lna
