Answer:
Associative property of multiplication
Step-by-step explanation:
The expression is solved as follows :
(4×5)×2=4×(5×2)
Associative property of multiplication is as follows :
(a×b)×c = a×(b×c)
In this problem,
a = 4, b = 5 and c = 2
Hence, Associative property of multiplication is used to solve the given expression.

Step-by-step explanation:
<u>Step 1: Define equation</u>
x + 5/9x = 2(3 - x)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: x + 5/9x = 6 - 2x
- Combine like terms: 14/9x = 6 - 2x
- Add 2x on both sides: 32/9x = 6
- Divide 32/9 on both sides: x = 27/16
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 27/16 + 5/9(27/16) = 2(3 - 27/16)
- Multiply: 27/16 + 15/16 = 2(3 - 27/16)
- Subtract: 27/16 + 15/16 = 2(21/16)
- Multiply: 27/16 + 15/16 = 21/8
- Add: 21/8 = 21/8
Here we see that 21/8 does indeed equal 21/8.
∴ x = 27/16 is a solution to the equation.
Step-by-step explanation:
x = angle 1
3x + 12 = angle 2
angle 1 + angle 2 = 180
4x + 12 = 180
4x = 168
x = 42 = angle 1
180 - 42 = 138 = angle 2
Answer:
The answer is 2.17 in decimal form. In fraction form the answer is 217/100. As a mixed fraction the answer is 2 17/100.
