Answer:
Second option!
Step-by-step explanation:
The x is -2, and as you can see the first one is at a positive 2, so the second one is the way to go.

Answer:
26 candy bars and 12 sodas
Step-by-step explanation:
This problem can be solved by a simple system of equations
I am going to call x the number of candy bars that Sally bought and y the number of sodas that Sally bought.
The fact that she bought 38 itens means the x + y = 38.
She spent $50.38. The value she spent is the sum of the number of candy bars multplied by the value of the candy bar and the number of sodas multiplied by value of a soda. So 1.25x + 1.49y = 50.38
So we have to solve the following system:
1)x + y = 38
2)1.25x + 1.49y = 50.38
From 1), we have that x = 38 - y. I am going to replace it in 2)
1.25(38-y) + 1.49y = 50.38
-1.25y + 1.49y = 50.38 - 47.5
0.24y = 2.88
y = 12.
Sally bought 12 sodas.
In 1: x = 38-y = 38-12 = 26
Sally bourght 26 candy bars
18.39 thats 18.386 rounded to the nerest hunderths
Answer:
C D H
Step-by-step explanation:
The best way to tackle this problem is to put each answer into the equation and evaluate the equation.
for example
-(-3.9) + 6 >= 10
3.9 + 6 >= 10
9.9 >= 10 .this is not true!
be very careful with the signs and evaluate each answer.
