I'm just trying to help. :)
Answer:
$80
Step-by-step explanation:
If we took 40% off that means that it now costs 60% of the original cost. So we are asking 60% of what number is 48?
Let x = the original cost
.6x = 48 Divide both sides by .6
x = 80.
Let's check.
What is 40% of 80?
.4 x 80 = 32. Subtract the discount from 80
80 - 32 = 48 The discounted price.
The radius is the square root of 16. So 4.
Total distance = sum of velocity * time for both legs of the journey; let the time taken in air be t hence time taken in water is 12-t 127 = 16*t + 3(12-t) 127 = 16t + 36 - 3t 127 - 36 = 16t - 3t 91 = 13t t = 91/13 = 7 seconds Hence time taken in air = 7 seconds time taken in water is 12 - 7 =<span> 5 seconds</span> checking; 16*7 + 3*5 = 127
Answer:
0
Step-by-step explanation:
An additive inverse is any number that adds to a certain number to make the value 0. For example, 6 has an additive inverse of -6. Therefore, -7 has an additive inverse of 7 because 7-7 (or -7+7)=0
