5x + 19.95 = 35 <br> Solve x
solniwko [45]

Answer:

Answer is x=3+0.05/5

Step-by-step explanation:

5x+19.95=35

We move all terms to the left:

5x+19.95-(35)=0

We add all the numbers together, and all the variables

5x-15.05=0

We move all terms containing x to the left, all other terms to the right

5x=15.05

x=15.05/5

x=3+0.05/5

I hope it's helpful!!

Express 8 1/5% as a mixed number or a fraction
Alexxandr [17]

Answer:

41/5

Step-by-step explanation:

First we change the 8 and 1/5% to 8.2%

Write the fraction down as a number over one = 8.2/1

Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

8.2/1 = (8.2 × 10)

(1 × 10) = 82/10

Reduce the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD (82,10) = 2. So, (82÷2)/(10÷2) = 41/5 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 82/10 is also equal to 81/5 when expressed as a mixed number.
