Answer:
x = 3
y = 8
Step-by-step explanation:
ok we will substitute
y = x + 5
into the second equation
4x + y = 20
4x + (x + 5) = 20
5x + 5 = 20
5x = 15
x = 3
y = x + 5 = 3 + 5 = 8
Answer:
n ≥ -3
Step-by-step explanation:
So, divide -27 by 9n and the answer to that is -3, because when you're dividing a negative number and a positive, the answer would always be negative.
This sign : ≥ means greater than or equal to, and because we are solving for n, -3 is equal to n.
Let x = quantity of bicycles
($160x) - ($80x) = $2800. To solve for x, we have to combine the terms on the left side.
$80x = $2800. Divide each side by $80.
x = 35.
35 bicycles must he sold each month to break even.
