Answer: a = 10.6

Pythag is a squared + b squared = c squared
We have c and b so we can sub those in to get a squared + 12 squared = 16 squared
Which equals a squared + 144 = 256
Then we - 144 from both sides to get a squared = 112
Then we square root 112 to get a = 10.6
Hope that helps

3. x + 4y = 30<br> x - 2y = 0

kolbaska11 [484]

Answer:

Step-by-step explanation:

Given that:

x + 4y = 30

x - 2y = 0

Subtracting both equations:

6y = 30

y = 30/6

y = 5

Putting in above equation

x + 4(5) = 30

x + 20 = 30

x = 10

Solution:

we have been asked to find

The expression is equivalent to $7/10-2/10$

we can simplify the given expression as below

$\frac{7}{10}-\frac{2}{10}=\frac{7-2}{10}\\ \\ \Rightarrow \frac{7}{10}-\frac{2}{10}=\frac{5}{10}\\ \\ \text{Simplify we get}\\ \\ \frac{7}{10}-\frac{2}{10}=\frac{1}{2}\\$
