That kinda means to see how many times 4 goes into 50 and write that as a percentage. Hoped I helped
X= number of adult tickets
y=number of child tickets.
we can suggest this system of equations:
x+y=118 ⇒x=118-y
7.5x+3y=696
we can solve this system of equations by substitution method:
7.5(118-y)+3y=696
885-7.5y+3y=696
-4.5y=-189
y=-189/-4.5
y=42
x=118-y
x=118-42
x=76
Answer: the number of adult tickets sold was 76.

Answer:
Three terms, which makes this expression a trinomial.
5x²-4x -12
Step-by-step explanation:
(5x + 6)(x-2)
5x² -10x + 6x -12
5x²-4x -12
Answer:
Step-by-step explanation:
<u>Expression on the board :</u>
<u>Expression by the student </u>:
<em><u> Expression 1 </u></em>:
The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.
<em><u>Expression 2 :</u></em>
<em><u /></em>
<em><u /></em>
The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.
