DOES ANYONE KNOW HOW TO DO THIS???

Answer:

Cost of a pound of chocolate chips: $3.5

Cost of a pound of walnuts: $1.25

Step-by-step explanation:

x - cost of a pound of chocolate chips

y - cost of a pound of walnuts

We create two equations based on the information we have:

3x+2y=13

8x+4y=33

The whole point of these problems os to get rid of x or y. In this question, we can do this by multiplying both sides of the first equation by 2, and then subtracting it from the second equation:

8x+4y=33

6x+4y=26

2x=7

x=3.5

Then we change x for 3.5 in the first equation:

3×3.5+2y=13

10.5+2y=13

2y=2.5

y=1.25

Hope this helps!

$7d + d - 4d - 7 = 5d$

$8d - 4d - 7 = 5d$

$4d - 7 = 5d$

$5d = 4d - 7$

Subtract sides 4d

$- 4d + 5d = - 4d + 4d - 7$

$d = - 7$

Thus the correct answer is Option three.
