Answer: A≈440.44
Step-by-step explanation:
X = books were sold on Saturday.
Because 2 more books were sold on Sunday than on Saturday, therefore
(x + 2) books were sold on Sunday.
The total number of books sold over the weekend (Saturday and Sunday) is
x + (x+2)
= x + x + 2
= 2x + 2
Answer: 2x + 2
Answer:
x=3, y=8; (3,8)
Step-by-step explanation:
To use the substitution method, first solve for a variable.
2x+y=14
2x+y(-2x)=14(-2x)
y=14-2x
Now substitute y in the other equation with 14-2x
5x-2(14-2x)= - 1
Simplify by multiplying inside the parenthesis.
5x-28+4x= - 1
Combine the x values
9x-28= - 1
9x=27
x=3
Now substitute the x value in to solve for y
2(3)+y=14
6+y=14
y=8
