Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:
-6x + y = -2
6x -18y = 54
--------------------
-17y = 52, or y = -52/17. Subst. this value of y into either equation to find the value of x.
Answer:
240
Step-by-step explanation:
you multiply to get an area for a shape
Answer:
the chance of getting heads when flipping a coin is 50%. As I cannot see the graphs, choose the one that shows 50%.
He has enough memory space to download a song that will use 0.12 gigabytes of memory
The memory capacity of new cell phone = 1.5 gigabytes
The memory capacity that already used = 1.35 gigabytes
The remaining space = The memory capacity of new cell phone - The memory capacity that already used
Substitute the values in the equation
Here we have to use the subtraction
The remaining space = 1.5 - 1.35
Subtract the terms
= 0.15 gigabytes
The size of the song = 0.12 gigabytes
We know 0.15 > 0.12
Hence, he has enough memory space to download a song that will use 0.12 gigabytes of memory
The complete question is
Devin has a new cell phone that holds 1.5 gigabytes if memory for music. He has already used 1.35 gigabytes of the memory. Will he have enough space to download a song that will use 0.12 gigabyte of memory? Explain.

Answer:
The Area of the bicycle wheel=380.182 square inch
Step-by-step explanation:
The formula for calculating the area of a wheel is given by;
A=(πd²)/4
A=Area of the wheel to be calculated
Where π (pie)=3.142,
The wheel size is usually denoted by its diameter (d)
d=diameter of the wheel=22 inches
with the values of π and d given, we can plug them in the formula for calculating Area to determine the area of the bicycle wheel
Substituting the values for π and d in the formula;
A=(πd²)/4=(3.142×22²)/4=380.182 in²
The Area of the bicycle wheel=380.182 in²
