Let
x = first integer
y = second integer
z = third integer
First equation: x + y + z = 194
Second equation: x + y = z + 80
Third equation: z = x - 45
Let's find the values of x, y and z.
Substitute 3rd eq to 1st eq:
x + y + x - 45 = 194
2x + y = 45 + 194
y = -2x + 239
Plug in both we have solved for y and the 3rd eq to the 2nd eq to find x
x + (-2x + 239) = (x - 45) + 80
x - 2x - x = -45 + 80 - 239
-2x = -204
x = -204/-2
x = 102
Solving for y,
y = -2(102) + 239
y = 35
Solving for z,
z = 102 - 45
z = 57
You move the decimal point forward until it reaches the one so it looks like this:
1.4 x 10⁵
the exponent, 5, just tells you how many spaces the decimal point moved.
When finding the volume of a cube, you would multiply the length x width x height. To find the volume, you would cube the length of one of the sides. For this problem, think of it as working backward because you're starting with the volume but need to know the length of a side. To do the opposite (or inverse) of cubing, you would instead find the cube root of the volume. The cube root of 3,944.312 cubic cm would give you 15.8 cm.
The formula for the volume of a cylinder is <em>v =

. </em>Take the numbers you are given in the problem and put them into the equation to get: <em>v +

. </em>After calculation this equation, you will get an answer of 160.8495. Just round to the nearest tenth to get 160.8.
Answer:
n = 1
Step-by-step explanation:
First, rearrange the equation to standard form 0 = ax² + bx + c, when everything equals 0.
5n² = 5
5n² - 5 = 0
State the variables a, b and c.
a = 5; b = 0; c = -5
Substitute a, b, and c into the quadratic formula.

Substitute
Simplify inside the √ and bottom
Simplify the top
Final answer
Therefore the solution is n = 1.
The quadratic formula usually is written with x, but it can be solved with any variable in standard form.
