Answer:

a=2

Step-by-step explanation:

12a - 5 = 4a + 11

Subtract 4a from each side

12a-4a - 5 = 4a-4a + 11

8a -5 = 11

Add 5 to each side

8a -5+5 = 11+5

8a = 16

8a/8 = 16/8

a =2

What is 54 percent as a fraction in simplest form
atroni [7]
54% is 54 out of 100.
There for the numerator is 54 and the denominator is 100.

\frac{54}{100}

Now, both the top and the bottom can be divided by 2. So:

\frac{54~divided~by~2}{100~divided~by~2} = \frac{27}{50}

\frac{27}{50} can't be simplified anymore, therefore, 27/50 is 54% as a fraction.

One of the legs of a right triangle measures 13 cm and its hypotenuse measures 17 cm. Find the measure of the other leg. If nece
sammy [17]

To find the lengths of a right triangle, we can use what is called Pythagorean Theorem: a^2 + b^2 = c^2, where a and b are the legs of the triangle and c is the hypotenuse.

13^2 + b^2 = 17^2

169 + b^2 = 289

b^2 = 120

b = 11.0 cm

The length of the other leg of the triangle is 11.0 cm (rounded).

Hope this helps!
