The equivalent expression for the given expression (w+9)+3 using associative property is w + 12
<u>Solution:</u>
Given that, expression is ( w + 9 ) + 3
We have to find how do we can use the associative property to write an expression equivalent to ( w + 9 ) + 3
The associative property states that you can add or multiply regardless of how the numbers are grouped
By above definition, we get
(a + b) + c = a + (b + c)
So, now let us apply the above property to the given expression,
Then, ( w + 9 ) + 3 = w + ( 9 + 3 ) = w + 12
Hence, the equivalent expression for the given expression is w + 12
The y-intercept appears to be at y=-1. The line appears to also go through grid point (3, 1), which is 2 units up and 3 units over. The slope is 2/3.
In slope-intercept form the equation of the line is
y = (2/3)x - 1
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
