Answer:
See below
Step-by-step explanation:
To get the fraction from mixed number you just need to take the number standing alone, multiply with the denominator and add with the numerator and keep it on top with the denominator in place to turn it into a fraction.
For example, [2]3/4 = 2*4 + 3 = 11 => the fraction is 11/4.
Answer:
A - It should be $2380.
Step-by-step explanation:
7 x 10 = 70 tiles needed total
70 x 34 = 2380

2nd equation:
8 x-y=10 ⇒ y= 8 x-10
We will switch that in 1st equation:
8 x-10=x²+12 x+30, or:
x² + 4 x +40 = 0, a=1,B=4, c=40
Discriminant : D= b² - 4 ac= 16 - 160 = -144 and because it is negative there are no real solutions.
Answer: D)
