Answer:
$30
Step-by-step explanation:
Let,
x - fiction book
x + $6 - novel
EQUATION:
4(x) + 2(x + $6) = $84
6x + $12 = $84
6x = $84 - $12
6x = $72
x = $12
SUBSTITUTE:
novel = $12
fiction = $18
TOTAL COST OF NOVEL AND FICTION
$18 + $12 = $30
Answer:
See attached graph
Step-by-step explanation:
Answer:
Step-by-step Solution:
<u>Let's simplify the equation to find the value of x.</u>
<u>[Simplify the Distributive property]</u>
<u>[Subtract 6 both sides]</u>
<u>[Solve the RHS]</u>
<u>[Divide -12 both sides to isolate the variable]</u>
<u>[Simplify the fraction]</u>
Hence, the value of x is -7/4.
Answer:
The number of children tickets sold was 610.
Step-by-step explanation:
Let
x ----> the number of adults tickets sold
y ----> the number of children tickets sold
we know that
x+y=1710 -----> equation A
50x+25y=70250 ----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (1100,610)
therefore
The number of children tickets sold was 610.
