Answer:Your answer is....
Step-by-step explanation:
80=5x+4y
Answer:
<h2>80=5x+4y</h2>
Step-by-step explanation:
Step one:
given
let binders be x
and notebooks be y
let the total sale be T
the cost of binder is $5 each
the cost of notebook is $4 each.
the total sales expected is $80
step two:
the linear model for the total sales is given as
T=x+y
using the given data, the situation can be represented linearly as
80=5x+4y
Therefore the linear expression for the total sale is 80=5x+4y

Answer:
x < -12
Step-by-step explanation:
-1/2x > 6
Multiply by -2 to isolate x
Remember that when multiplying by a negative, we flip the inequality
-2 * -1/2x < 6*-2
x < -12
Answer:
6(2x-3)= -9 given
12x-18= -9 distribute
12x-18+18= -9+18 addition
12x= 9 division
