I think this is the Transitive postulate of equality.
Personally I can't see much point in giving labels to these equalities.
Answer:
A = 140
Step-by-step explanation:
Area of a triangle:
A = 1/2bh
Given:
b = 20
h = 14
Work:
A = 1/2bh
A = 1/2(20)(14)
A = 10(14)
A = 140
Try this option:
1. according to the condition Kris scored '2x' points, Julio did 'x' points (Kris scored 2 times as many points as Julio).
2. according to the condition Kris'_points+Julio's_points=36_points. It means, that x+2x=36.
3. If to solve this equation (2x+x=36), then Julio scored x=12 points, Kris scored 2x=12*2=24 points.
answer: 12 (Julio); 24 (Kris).
Answer:
Commutative Property of Multiplication
Step-by-step explanation:
Commutative Property of Multiplication is the switching of the order first factor (multiplicand) and the second factor (multiplier), which does not change the product. For example, 4 × 5 = 5 × 4
-5 × 12 = -60
12 × -5 = -60
