A net is a pattern made when the surface of a three-dimensional figure or solid is laid out flat showing each face of the figure. It is then possible to use the net to calculate the surface area of the solid.
Surface Area of a Cube using Nets
A cube is a three-dimensional figure with six matching square faces.
22 = z + (-9) Switch the sides
z = 22 - (-9) Solve
z = 31 So, z = 31
Answer:
Part 1)
Part 2)
Step-by-step explanation:
Let
y ----> the total amount of savings
x ----> the number of months
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
<em>Herman</em>
The slope is equal to
The y-intercept is
substitute
----> equation A
<em>Jackie</em>
The slope is equal to
The y-intercept is
substitute
----> equation B
Part 1) In how many months will they have the same amount of savings?
equate equation A and equation B
solve for x
Part 2) How much will each of them have saved?
substitute the value of x=10 months in any of the equations
equation A
equation B
