I think you get 35% by first adding up everyone that was surveyed so
<span>190+135+220= 545 </span>
<span>Next you would divide 190 by the total number of people surveyed so </span>
<span>190/545= 0.348... </span>
<span>Since there is an 8 next to the 4 you would round up therefore getting 35% </span>
<span>I think that is how they got 35%</span>
Answer:
Equation: 139 + 3x + (5x - 10) + (10x - 9) + 3x = 540 (not simplified, see below for simplified)
x = 20
Step-by-step explanation:
If the sum of the angles is 540°, then that means you add them up to get 540°.
139 + 3x + (5x - 10) + (10x - 9) + 3x = 540
129 + 8x + (10x - 9) + 3x = 540
120 + 18x + 3x = 540
120 + 21x = 540
21x = 420
x = 20
It is 8 the answer your welco
Yes it is. rational #s can be expressed in the form of a fraction. where the numerator and the denominator do not equal zero.
