Match the steps with equivalent properties
Step 1: Multiplicative Identity Property
This states that:
So, the expression becomes:
Step 2: Distributive Property
This states that:
So, the expression becomes
Step 3: Addition
Here, we simply add the expressions in the bracket
Step 4: Commutative Property of Multiplication
This states that:
So, we have:
Answer:
729
Step-by-step explanation:
9 x 9 = 81
81 x 9 = 729
Can you show me the equation
Answer:
.5
Step-by-step explanation:
Going from WHB to RVM means that we need the number to multiply by to get to RVM, the smaller triangle.
Multiplying by .5 is the same as dividing by 2.
20 x .5 = 10
16 x .5 = 8
12 x .5 = 6
Answer:
A -6 < x ≤ -3
Step-by-step explanation:
21 ≤ - 3(x - 4) < 30
Divide all parts by -3. Remember that flips the inequalities
21/-3 ≥ - 3/-3 (x - 4) > 30/-3
-7 ≥ (x - 4) > -10
Add 4 to all sides
-7+4 ≥ x - 4+4 > -10+4
-3 ≥ x > -6
Rearranging the order
-6 < x ≤ -3
