Answer:
One solution
Step-by-step explanation:
Let us first <u>expand</u> the left side of the equation to rid of the parenthesis:

Now let us <u>isolate</u> the variable to sove for x:

Therefore, x=
. As you can see, there is just one solution.

Answer:
153.94 cm²
Step-by-step explanation:
Area of circle = πr² = π(7)² = 49π = 153.94 cm²
First lets simplify both side of this equation.
2 + 7 + ♢ = 3 + 6 + 5
Subtract 9 from both sides of the equation.
9 + ♢ = 14
Answer (C)
♢ = 5
Answer:
30000
Step-by-step explanation:
30 x 1000
So we have the equations:
y - 4x = 2 --- equation 1
5y - 2x = 1 --- equation 2
(equation 2) * 2
10y - 4x = 2 --- equation 3
(equation 2) - (equation 3)
-9y = 0 so y= 0 and thus x = -1/2
Hope that helps!
