Answer:
132 tiles
Step-by-step explanation:
Each tile cost $4
The adhesive/grouting material costs $17.82.
If the contractor pays a total of $545.82
Let the number of tiles be represented as x
The equation is represented as:
$17.82 + $4 × x = $545.82
17.82 + 4x = 545.82
Collect like terms
4x = 545.82 - 17.82
4x = 528
Divide bother sides by 4
4x/4 = 528/4
x = 132
The number of ceramic tiles the contractor bought = 132 tiles
Answer:
5x - 2y = -2
Step-by-step explanation:
-2x - (-7x) = -2x + 7x = 5x
y - 3y = -2y
0 - 2 = -2
The square of a binomial is written like
In your case, you have 
, which implies 
So, we want to write
But our left hand side is
If we add 26 to both sides, we have
