Answer:
x = 49
The equation does have a solution
Step-by-step explanation:
The sqrt of x = 7, does have a solution. Simply remove the radical, and raise each side by the index of the radical.
In more basic terms, what number has the sqrt of 7? 7^2 is equal to 49!
Yes they are equivalent. This is because if you simplify each fraction : 288/12 and 240/10 they both equal 24.

The answer is A because all three of them have the same amount of coins
Answer:
V = 64 and V = 2,048
Step-by-step explanation:
The volume of a cube is found using V = s*s*s. Substitute s = 4.
The volume is V = 4*4*4 = 64.
The volume of the crate is 32 * 64 = 2,048.
Answer:
$52
Step-by-step explanation:
Using the equation
y=mx+c
82=7x+c
122=11x+c
11x-7x=122-82
4x=40
x=10
To get c
82=7(10)+c
82-70=c
c=12
For 4 lessons
y=10(4)+12=52
