Step-by-step explanation:
X is the missing number
Answer:
(4,3)
Step-by-step explanation:
Given
x^2+y^2=25
x-y^2=-5
In order to solve the equations, from equation 2 we get
-y^2= -5-x
y^2=5+x
Putting the value of y^2 in equation 1
x^2+5+x=25
x^2+5-25+x=0
x^2+x-20=0
x^2+5x-4x-20= 0
x(x+5)-4(x+5)=0
(x+5)(x-4)=0
So
x+5=0 x-4=0
x=-5 x=4
Now for x=-5
x^2+y^2=25
(-5)^2+y^2=25
25+y^2=25
y^2=25-25
y^2=0
so Y=0
And for x = 4
x^2+y^2=25
(4)^2+y^2=25
16+y^2=25
y^2=25-16
y^2=9
y= ±3
So the solution to the system of equations is
(-5,0) , (4,3), (4,-3)
The only solution that belongs to first quadrant is (4,3)

42/63 = 50/x
2/3 = 50/x
x = 75
1/3 will become 2/6.
Steps in adding fraction.
Step 1. Make sure that the denominators are the same:
5/6 + 1/3 * 6 and 3 are the denominators. they are not the same. however, 6 is twice the number of 3. Thus, multiply 2 to the numerator and denominator of 1/3
1/3 * 2/2 = 2/6
5/6 + 2/6
Step 2. Add the numerators. Put the sum above the common denominator.
(5+2) / 6 = 7/6
Step 3. Simplify the fraction.
7/6 = 1 1/6
