Answer:
= y > -272
Step-by-step explanation:
Well t would be 6/10 9/15 and u just add 3 to the numerator and 5 to the denominator
Answer:
x = -1.
Step-by-step explanation:
√(x + 10) - 4 = x
√(x + 10) = x + 4
Squaring both sides:
x + 10 = x^2 + 8x + 16
x^2 + 8x - x + 6 = 0
x^2 + 7x + 6 = 0
(x + 6)(x + 1) = 0
<u>x = -6, -1.</u>
Check for any extraneous roots:
√(x + 10) - 4 = x
<u>Try x = -6:</u>
√(-6 + 10) - 4 = 2 - 4 = -2.
but we found x = -6 , so -6 is not a root.
<u>Try x = -1</u>:
√(-1 + 10) - 4 = 3 - 4 = -1. So x = -1 is a root.
-- least common multiple of 36, 6, 3 = 36
- it is the smallest number divisible <u>by all three. </u>
Answer:
I am not sure if my math is correct but I got $15 dollars in change.
Step-by-step explanation:
$50 times 0.10 (10%) equals $5. $50.00 minus $30.00 is $20.00. $20 minus $5 is $15.
