Answer:
One number is 561
The other number is 23.6854
Step-by-step explanation:
x = y^2 One number = the square of another
x + y^2 = 1122 The sum of the two numbers is 1122
Substitute y^2 in for x on the second equation.
y^2 + y^2 = 1122 Combine like terms on the left
2y^2 = 1122 Divide by 2
y^2 = 1122/2
y^2 = 561 Take the square root of both sides.
y = 23.6854
x = y^2
x = 561
y^2 = 561
Answer:
1/3x + 1
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
3x - 6y = - 12 → (1)
x - 2y = 10 → (2)
Rearrange (2) expressing x in terms of y by adding 2y to both sides
x = 10 + 2y
Substitute x = 10 + 2y into (1)
3(10 + 2y) - 6y = - 12 ← distribute left side
30 + 6y - 6y = - 12 ( subtract 30 from both sides )
0 + 6y - 6y = - 12 - 30 , that is
0 = - 42 ← not possible
This indicates that the system of equations has no solution.
The 2 lines must therefore be parallel with no intersection
Surface area of larger box is 69% more so as a scale factor that is 1.69
Square root 1.69 = 1.3
Height of smaller box x 1.3 is height of larger box.
18 x 1.3 = 23.4 cm
Height = 23.4 cm
