Answer:
10.7
Step-by-step explanation:
add multiple than subtract what you multiple and add a decimal
we have
x=5−2y ---> multiply by 3 both sides-----> 3x=15-6y-----> 6y=15-3x----> equation 1
6y=10−3x------> equation 2
equation 1 and equation 2 has the same slope
the lines are parallel
slope m=-3/6-----> m=-1/2
so
there are no solution
the answer is the option
b. There is no solution
Answer:
$ 2250
Step-by-step explanation:
3375 = s³
s = ∛3375
s = 15 ft.
floor area = s² = (15 * 15)
floor area = 225 ft²
the contractor charges $10 per ft².
therefore,
the hardwood cost = 225 x $10 = $2250
I am also not sure, because I also asked this question.
Answer:
15x + 20y
Step-by-step explanation:
First, we need to combine like terms,
10x + 20y + 5x
15x + 20y
Since x and y are different variables, we cannot combine them, meaning that the answer is,
15x + 20y
