Answer:
Step-by-step explanation:
We are asked to find the difference which means we will be using subtraction.
We are given two numbers to use 
(Houston to Dallas) & 
(San Antonio to Houston).
To be able to subtract, we need to have the same denominator on both fractions, which we can do by multiplying 1/3 by 4
now we can subtract the numbers and simplify!
decrease = 9%
percent decrease = 
× 100%
decrease = $98 - $89 = $9
percent decrease = 
× 100% = 9% (to nearest whole percent )
Answer:
a = ±sqrt(3)
Step-by-step explanation:
a×a×a=a+a+a
Simplifying each side
a^3 = 3a
Divide each side by a
a^3 /a = 3a/a
a^2 = 3
Take the square root of each side
sqrt(a^2) = ±sqrt(3)
a = ±sqrt(3)
Answer:
$25
Step-by-step explanation:
18.75 is 75% of a value. You can easily find the answer by dividing 18.75 and 0.75.
When you have a problem like x*5=30, you divide 30/5 to get 6. Same here, x*0.75=18.75. Divide 18.75/0.75 to get the answer.
