Answer:
3/5
Step-by-step explanation:
It is 3/5 because you can divide by 10 on the top and bottom. 30/50=3/5
Add alike terms. Basically you add stuff together with the same variable! Since -8y and +3y have a y variable, they can be added together. Same with x.
-8y + 3y = -5y. This is because you’re adding 3 from a negative number.
5x - 9x = -4x. You’re subtracting 9 from a positive number.
That is as simple as it can get, so you put those two numbers in the same equation.
The simplest expression is:
-5y - 4x
This comes from subtracting 4 from both sides.
Answer: 10.4
Step-by-step explanation:
According to the right angle triangle, the longest side is the hypothenus, d side facing the angle is the opposite and the other side is the adjacent
So we this we will use tan
Tan 30= opp/adj
Tan 30= 6/x
Cross multiply
Xtan30= 6
X= 6/tan 30
X= 6/1/square root of 3
X= 6 x square root of 3
X= 10.39 ~ 10.4
