For the 20% off, we can make the following rule of three:
7.50 --------------> 100%
x ------------------> 20%
From here, we clear the value of x.
We have then:
Then, subtracting both values we have:
For taxes we have:
6 ---------------> 100%
x'---------------> 5.75%
Clearing the value of x' we have:
Then, adding both values we have:
Answer:
7.50 admission; 20% off; 5.75% tax is:
6.345
Answer: He will need to assemble 12 bikes, because 12 x 15.50 = $186 and $186 + 150 = $336
Step-by-step explanation: Don't need one :)) it's basic math
The mathematical sentence can be written as:
5/(a + b).
Here we have a mathematical sentence and we want to write as an expression.
"5 divided by the sum of a and b".
The sum of a and b is just written as:
a + b
And we must have 5 divided by that, so we just write this like a quotient:
5/(a + b).
This is the expression that is equivalent to the mathematical sentence.
If you want to learn more about quotients, you can read:
5/a+b
sum means addition which divided obviously means division so....
