Answer:
Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different. In an expression, only like terms can be combined. We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily.
Answer:
child buffet = $16, adult buffet =$23
Step-by-step explanation:
lets assume that child buffets costs, $x
and adult buffets costs $y
2x+4y= $124 .............this is our first equation
x+4y =$108 ................our second equation
<em>2x + 4y = 124</em>
<em>2x = 124 - 4y</em>
<em>x = 62 - 2y ....from first equation</em>
---------------------------------------------------------------------------------------------------
<em>x+4y =$108</em>
<em>x = 108 -4y ... from second equation</em>
---------------------------------------------------------------------------------------------------
now we will solve it through simultaneous equations
<em>62 - 2y = 108 -4y</em>
<em>2y = 46</em>
<em>y = $23</em>
<em>if y =$23</em>
<em>then x = 108 - 4(23)</em>
<em>x = $16</em>
