X=(180-50-55)
x=75°
............
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
The correct answer is A because product means multiply
Hope this helped :)
This is a simple ratio. x : y. So x = 21 when y = 5.
21 : 5.
x : 25
So you are timesing each side by 5
So 21 x 5 = 105.
x = 105
