Answer:
60
Step-by-step explanation:
Of means multiply and is means equals
Let n be the unknown number
135% * n = 81
Change to decimal form
1.35 n = 81
Divide each side by 1.35
1.35n/1.35 = 81/1.35
n =60
Answer:
3² or 9
Step-by-step explanation:
Step 1: Add exponents

Step 2: Subtract exponents
You should get 3² because of exponent rules. Remember when you multiply exponents you add the powers and when you divide exponents you subtract the powers.
Answer:
The given system has INFINITE NUMBER OF SOLUTIONS.
Step-by-step explanation:
Here, the given system of equation is given as:
2 x - 4 y = 12 ... (1)
- x + 2 y = -6 ...... (2)
Now, to use the ELIMINATION METHOD we either need to cancel out x coefficients or the y coefficient.
Now, to cancel out the x- coefficient in both the equations:
Multiply equation (2) with 2 and add with (1), we get:
2 x - 2x + 4 y - 4 y = 12 - 12
or, 0 = 0
Hence, the given system has INFINITE NUMBER OF SOLUTIONS.
