Answer:
x=4/3, y=2
x=8/3, y=10/3
x=22/3, y=24/3
Step-by-step explanation:
By following the rule given, you can insert the values you already know to find the values that you don't know!
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a 2 − b 2 = ( a + b ) ( a − b ) where a = 7 and b = a + x . − ( 7 + a + x ) ( a + x − 7 )
Answer:
17.32
Step-by-step explanation:
since there is a 5 in the thousandths, we round the 1 in the hundredths up and get 17.32
Let x be the 1st number
x + 9 be the second number
Equation:
x + x+9 = 171
Solution:
2x + 9 = 171
2x = 171 - 9
2x = 162
x = 81
x + 9 = 90
81 + 90 = 171
