Answer:
D 36
Step-by-step explanation:
<em>Write the information algebraically</em>
c = 3a
c + a = 48
c = children, a = adults
<em>In the second sentence (in bold), we can replace c with 3a</em>
c + a = 48 → 3a + a = 48
<em>Simplify</em>
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
<em>We can then substitute or plug in a = 12 into the original equation:</em>
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)
<h3>There are 36 children</h3>
Answer:
I believe it's 2x²-8x + 1
Step-by-step explanation:
Combine like terms
2x²- 3x - 5x + 1
2x²- 8x + 1
Well the first thing you have to do is find the sum of the numbers given. 5.2 + 8.3 + 8.5+ 7.7+ 7.8= 37.5
the equation would now be 37.5+y/6 = 7.1
After this you multiply 7.1 by 6 which is 42.6 turning the equation to 37.5 + y = 42.6.
Then you subtract 37.5 from 42.6 making y =5.1
0.4x 0.4x 0.4 = (0.4)^3
Exponential form = (0.4)^3
C) will not effected (the most frequent is still 600$)
