First we will find out the values of a
a/4=b/7
a=4b/7
Now
(a-b)/b
{4b/7-b}/b
(4b-7b)/7b
-3b/7b
-3/7
Answer:
x = 152/5 or x = 30.4 decimal
Step-by-step explanation:
Solve for x:
5 x - 152 = 0
Add 152 to both sides:
5 x + (152 - 152) = 152
152 - 152 = 0:
5 x = 152
Divide both sides of 5 x = 152 by 5:
(5 x)/5 = 152/5
5/5 = 1:
Answer: x = 152/5
Hello there! 46.62 rounded to the nearest dollar is 47. That's because the tenths digit is greater than 5, so we round up from 6 to 7. The new number is 47. Now, we can multiply by 15% to find the approximate amount of the tip, because that will get us to 15% of the amount. 47 * 15% (0.15) is 7.05. The amount of the tip is approximately $7.05.
