Rectangle- A=bh triangle- A=0.5bh trapezoid- A= ( base 1 + base 2) h divided by 2
This is the table=
A B
1 3.5 3.75
40 140 150
100 350 375
so more cheaper is printer A
Answer:
Equation 1 = Equation 2
165 - 4x = 145 - 3.50x
Step-by-step explanation:
Let x represent the number of 30-day periods.
Tavon has a gift card for $165 that loses $4 for each 30-day period it is not used.
Therefore the equation =
$165 -$4 × x
= 165 - 4x.......... Equation 1
He has another gift card for $145 that loses $3.50 for each 30-day period it is not used.
$145 -$3.50 × x
= 145 - 3.50x........... Equation 2
Hence, an equation for the number of 30-day periods until the value of the gift cards will be equal is obtained by equating Equation 1 and Equation 2 together
So, we have
Equation 1 = Equation 2
165 - 4x = 145 - 3.50x
We simplify further:
165 - 145 = -3.50 + 4.0x
20 = 0.5x
x = 20/0.5
x = 40
Therefore, number of each 30-day periods until the value of the gift cards will be equal is 40

100-4.3= 95.7%
15000(.957)^12
Answer:
Step-by-step explanation:
Compare the equation with y = mx + b where m is slope and b is y intercept
y = (5/4)x - (7/4)
Slope = m = 5/4
