I have solved the answer in the pic below, hope it helpss!!!!
Let's set up some simultaneous equations. Let the number of nickels be n, and the number of quarters be q. Now I'm from England so I had to look up the value of a nickel (I could guess the quarter though to be 25c), but apparently it's 5c
Okay we know that the total value of the coins is 150. This gives:
25q + 5n = 150
Rearranging to make n the subject:
n = 30 - 5q
Next, we use the second statement:
n = 2q - 5
Substituting this into the first equation:
2q - 5 = 30 - 5q
7q = 35
q = 5
Putting this value for q into the first equation:
n = 30 - 5(5) = 5
Hence he has 5 of each coin. I hope this helps :)

Answer:
d. Jessica can have up to 7 toppings on her pizza
Step-by-step explanation:
We know that the inequality that gives us the number of toppings Jessica can put on her pizza is
where
, so, to find the number of topics we just need to solve the inequality.
Let's do it step-by-step
Step 1. Subtract 9.50 from both sides of the inequality


Step 2. Distribute 0.75 to the two terms inside the parenthesis

Step 3. Add 0.75 to both sides of the inequality


Step 4. Divide both sides of the inequality bu 0.75


Jessica can put up to 7 topping on her pizza.
We can conclude that the correct answer is d. Jessica can have up to 7 toppings on her pizza
28 is the correct answer:)
