We have learned that, in in an algebraic expression<span>, letters can stand for numbers. When we substitute a specific </span>value<span> for each variable, and then perform the operations, it's </span>called<span> evaluating the </span>expression<span>. Let's evaluate the </span>expression<span> 3y + 2y when 5 = y.</span>
Answer:
He would have earned 1150$.
Step-by-step explanation:
25 x 30 = 750$
50 x 8 = 400$
400 + 750 = 1150$
Sum=14 + 37 + 22 + 56 + 33 = 152 => 100%
red = 14 => x%
100% / 152 = x / 14
x = 100 × 14 / 152
x = 1400 / 152
x = 9,21% = 9%
We have that
<span>1/4 x + 2/3 y = 5 ----> multiply by 12 both sides---> 3x+8y=60
1/2 x + 3/2 y = 11---> multiply by 2 both sides----> x+3y=22
therefore
the answer is the option
</span><span>B. 3x + 8y = 60 ; x + 3y = 22</span>
