Find the value of x.
A) 71
B) 72
C) 73
D) 75
Answers
Subtract 146° on both sides.
(-39 +x)° = 180° - 146°
(-39 +x)° = 34°
(x - 39)° = 34°
Add 39° on both sides
x = 34° + 39°
x = 73°
Your final answer is C) 73.
107 + x = 180
x = 73
Your answer is C) 73.

An increase by 15% means 15 added to per cent (per = each; cent=100).
If the population was 100 in the year 2000 then it would be 115 in the year 2014. (adding 15 to 100)
The population was 116500 in the year 2000 and it increased to 133975 in the year 2014.
Let the population be x in the year 2000.
Using ratio and proportion
Year 2000 : Year 2014
100 : 115
x : 133975
Applying cross product rule
x × 115= 100× 133975
x= 100× 133975/115
x= 116500
The population was 116500 in the year 2000 and it increased to 133975 in the year 2014.
Answer:
116500
Step-by-step explanation:
We are looking for the number of twin births in 2000.
Let the number of twin births in 2000 be x.
The number of twin births in 2000 is 100% of the number of births in 2000 since 100% of something is the entire thing.
The number of twin births went up 15% from 2000 to 2014, so in 2014, the number of twin births was 100% of the number of twin births plus another 15% of the number of twin births.
100% + 15% = 115%
The number of twin births in 2014 was 115% of x.
The number of twin births in 2014 was 133975.
115% of x = 133975
115% * x = 133975
1.15x = 133975
x = 133975/1.15
x = 116500
The number of twin births in 2000 was 116500.

Answer: choice D
2x^5 - 6x^3 + 3x^2 - x
Explanation:
Polynomials in standard form always have the exponents decrease (ie go from largest to smallest) when we read from left to right. For choice D, the exponents from left to right are: 5, 3, 2, 1. This is decreasing order. The other answer choices do not have the exponents in decreasing order. The degree of the polynomial in choice D is a 5th degree polynomial since 5 is the largest exponent.

When you see math printed or written, " % " means " /100 ".
So " .5% " means " .5/100 ".
If you simplify that, or write it as a decimal, you get 1/200 or 0.005 .
Either way, " .5 " is greater.
