Answer: 13/25
Step-by-step explanation: Think of 0.52 as fifty-two hundredths which can be written as the fraction 52/100.
Since 52/100 is not in lowest terms, we divide the numerator and the denominator by the greatest common factor of 52 and 100 which is 14 and we get the equivalent fraction 13/25.
Therefore, 0.52 is equivalent to 13/25.

Answer:
81/64
Step-by-step explanation:
(-8)^-2
----------------
3^-4
Negative exponents move the item from the numerator to the denominator, and from the denominator to the numerator
(3)^4
----------------
(-8)^2
Now evaluate the power

Answer:
b =15
Step-by-step explanation:
The sum of the angles of a triangle is 180
5b+ 4b+ 3b = 180
12b = 180
Divide by 12
12b/12 =180/12
b =15
<span>Simplifying
4x2 + -24x + 4y2 + 72y = 76
Reorder the terms:
-24x + 4x2 + 72y + 4y2 = 76
Solving
-24x + 4x2 + 72y + 4y2 = 76
Solving for variable 'x'.
Reorder the terms:
-76 + -24x + 4x2 + 72y + 4y2 = 76 + -76
Combine like terms: 76 + -76 = 0
-76 + -24x + 4x2 + 72y + 4y2 = 0
Factor out the Greatest Common Factor (GCF), '4'.
4(-19 + -6x + x2 + 18y + y2) = 0
Ignore the factor 4.
