Answer:
33 1/3% decrease
Step-by-step explanation:
The original area is (6in)(10in) = 60 in². The reduced area is (5in)(8in) = 40 in². Then the change in area is ...
((new value)/(old value) -1) × 100%
(40/60 -1)×100% = -1/3×100% = -33 1/3%
The area decreased by 33 1/3%.

Answer:
(c) 5y - x = -20
Step-by-step explanation:
When the x- and y-terms are on the same side of the equation, the slope of the line will be ...
m = -(coefficient of x)/(coefficient of y)
So, the slopes of the offered choices are ...
a) -5/1 = -5
b) -1/5
c) -(-1)/5 = 1/5 . . . . . parallel to given line
d) -5/-1 = 5
The lines will be parallel when their slopes are the same. The slope of the given line is the coefficient of x, 1/5. Choice C has the same slope.
The
negative exponent rule says that when a base has a negative exponent, flip the base onto the other side of the fraction to make it into a positive exponent. For example,
.
Also remember that the <span>
zero exponent rule says that</span> any number raised to zero is 1. For example,
.
Back to the Problem:To fill out the table, you want to plug in the x-values you're given in the first row into
to get the y-values in order to fill in the second row.
The missing y-values are for when x = -2, x = 0, and x = 2.
Find x = -2. Use the negative exponent rule
:Find x = 0.<u /> Use the zero exponent rule:
Find x = 2. -------

Answer:
width= 27 ft, length=78 ft
Step-by-step explanation:
P=2l+2w
210=2l+2w
Divide by 2
105=l+w
l=5w-57
Substitute for l
105=6w-57
6w=162
w=27
l=5(27)-57
=135-27
l=78
