Answer:
-4/3
Step-by-step explanation:
Using the order of operations you can simply go from left to right with it.
5x2 + 3y2 = 2
10 + 3y2 = 2 Here I just multiplied 5x2
Now we can continue with the equation, keeping in mind you go left to right.
10 + 3y2 = 2
10+ 6y = 2 3y times 2 is 6y.
So we have to continue by balancing the equation, what you do to one side you do to the other.
10 + 6y = 2
<u>-10 -10</u>
6y = -8
6y/6 is y and -8/6 can be reduced to -4/3 so that is the answer!
Hope that helps and have a great day!
Answer:
3. 45, 4. 24
Step-by-step explanation:
use formula: hypotenuse²= side² + other side ²
3.
x²= 27²+36² calculate the squares then add
x²=2025 square root both sides
x= √2025= 45
4.
25²= x²+7² isolate the vaiable by subtracting 7² from both sides
25²-7² = x² square then subtract
576 =x² square root both sides
24=x
