Answer:
$135
Step-by-step explanation:
We can answer this by multiplying $150 by (1.00 - 0.10), or by 0.90:
0.90($150) = $135.
Note that 1.00($150) = $150 (full price)
and that 0.10($150) = $15 (discount)
and that (0.90)($150 = $135 (the fastest way to calculate the final (sale) price.
Answer:
Below.
Step-by-step explanation:
As both the right sides of the 2 equations are equal to y, by the transitive law of equality 3x + 1 = -2x + 3.
W then solve this equation for x then substitute this value of x in the first equation ( y = 3x + 1) to find the value of y.
