Answer:
77.41
Step-by-step explanation:
4.6² + 7.5²= 77.41
Square root of 77.41:
√77.41
This is because it can not be simplified further!
Why?
Because we used the Pythagoras Formula which is a²+ b² = c².
This is also why we had to find the square root of 77.41.
I would go about solving this by elimination because the x variables are already the same so all you would have to do is change one equation to the opposite signs and add them, so it would look like:
7y + 5x = 19
+ -3y - 5x = -7
-------------------
4y=12
y=3
Answer:
x=1
Step-by-step explanation:
3/2+1/2x=2x
Multiply each side by 2 to get rid of the fractions
2(3/2+1/2x)=2x*2
3+x = 4x
Subtract x from each side
3+x-x = 4x-x
3 = 3x
Divide each side by 3
3/3 = 3x/3
1 =x
