In algebra, symbols are used to represent numbers. Example: 5x=20 or 4x=24
Answer is b.
Now we going to solve it
To find how many refills he bought
8.95 + 1.50(r) = 26.95
-8.95 = -8.95 1. subtract $8.95 from
———————————- both sides.
1.50(r) = 18.00 2. The $8.95 cancels
——— = ——— out.
1.50 1.50 3. Bring the equation
R = 12 down.
4. Now you divide 1.50
on both sides.
Final answer R= 12

Answer:
3 Credit Courses = 37
4 Credit Courses = 11
Step-by-step explanation:
1. Set up 2 equations:
3x + 4y = 155
x + y = 48
2. Simplify the second expression for x by subtracting y from both sides
x = 48 - y
3. Substitute 48 - y for x
3(48-y) + 4y = 155
4. Simplify the expression by multiplying by 3
144 - 3y +4y = 155
5. Subtract 144 from both sides and subtract 3y from 4y
y = 11 = 4 Credit Courses
6. Substitute y for equation 2
x = 48-11
7. solve for x
x = 37 = 3 Credit Courses
