Square root is this 4 and -4 are square roots to 16 because 4^2= 16
Luis earns a solid $150 and that doesn't change, now you need to calculate 14% of $6,050.
x=150+(0.14x6050)
150+(847)
997
Luis was paid $997.
7x - 5y = 21....(4,?)...so sub in 4 for x and solve for y
7(4) - 5y = 21
28 - 5y = 21
-5y = 21 - 28
-5y = - 7
y = 7/5
check..
7(4) - 5(7/5) = 21
28 - 35/5 = 21
28 - 7 = 21
21 = 21 (correct)
the other coordinate is 7/5......(4,7/5)
$200 divided by 100 customers = 2$.
So, if he wants to make a profit of $200, he would have to make each customer pay $2. :)
The two figures are congruent because the side lengths are the same, therefore making the angle measures the same.
