The dependent variable is the cost of the pizza.
The Independent variable (or what you manipulate) is the toppings of the pizza, and the dependent variable (or what changes because you manipulated something) is the total cost of the pizza

Step-by-step explanation:
Cross multiply, separate variables terms and constant terms.
Answer:
u = 3/4
Step-by-step explanation:
Solve for u:
-5 (6 - 4 u) - 6 u = 6 (u - 3) - 6
-5 (6 - 4 u) = 20 u - 30:
20 u - 30 - 6 u = 6 (u - 3) - 6
Grouping like terms, 20 u - 6 u - 30 = (20 u - 6 u) - 30:
(20 u - 6 u) - 30 = 6 (u - 3) - 6
20 u - 6 u = 14 u:
14 u - 30 = 6 (u - 3) - 6
6 (u - 3) = 6 u - 18:
14 u - 30 = 6 u - 18 - 6
Grouping like terms, 6 u - 18 - 6 = 6 u + (-18 - 6):
14 u - 30 = 6 u + (-18 - 6)
-18 - 6 = -24:
14 u - 30 = 6 u + -24
Subtract 6 u from both sides:
(14 u - 6 u) - 30 = (6 u - 6 u) - 24
14 u - 6 u = 8 u:
8 u - 30 = (6 u - 6 u) - 24
6 u - 6 u = 0:
8 u - 30 = -24
Add 30 to both sides:
8 u + (30 - 30) = 30 - 24
30 - 30 = 0:
8 u = 30 - 24
30 - 24 = 6:
8 u = 6
Divide both sides of 8 u = 6 by 8:
(8 u)/8 = 6/8
8/8 = 1:
u = 6/8
The gcd of 6 and 8 is 2, so 6/8 = (2×3)/(2×4) = 2/2×3/4 = 3/4:
Answer: u = 3/4
Answer:
60°
If all sides are equal then this is an equilateral triangle.
In equilateral triangles, all angles are the same and sicne the interior angles of any triangle add to 180, all the angles of this triangle are 60°
