Answer:
7^(1-3+1) = 7^-3
Step-by-step explanation:
Here is the rule you should know: when multiplying powers of the same base you add the exponents ans when dividing powers of the same base you subtract the exponents.
Also, if there is no number at the exponent, it is 1.
Answer:
I think the answer is C.
Step-by-step explanation:
The law of exponents states that when you divide the same base you subtract the exponents.
Answer:
The answer would be 4.6
Step-by-step explanation:
4.58
8 is closest to 10 so round the 5 to 6.

2(2x</span>²/2 + 2x/2 - 24/2)

5x+4y = 73
-4x + 4y = -8
5x + 4y -(-4x+4y) = 73 -(-8)
5x + 4y + 4x - 4y = 81
5x + 4x + 4y - 4y = 81
9x = 81
x = 81÷9
x = 9
Substitute x = 9 into any of the equations to find y.
5(9) + 4y = 73
45 + 4y = 73
4y = 73 - 45
4y = 28
y = 28÷4
y=7
Answers :
x = 9
y = 7
