Answer:
A. 2 ( 10 x − 5 )
D. 10 ( 2 x − 1 )
Step-by-step explanation:
Given expression:
20x − 10
Find the equivalent expression
Check all that applies
A. 2 ( 10 x − 5 )
= 20x - 10
B. 2 ( 2 x − 1 )
= 4x - 2
C. 10 ( 20 x − 10 )
= 200x - 100
D. 10 ( 2 x − 1 )
20x - 10
The correct options are
A. 2 ( 10 x − 5 )
D. 10 ( 2 x − 1 )
If I understand ur question correctly, the first one:
(16x^4)^(1/4) = 2*abs(x)
Answer:
The arc length of the partial circle is 
Step-by-step explanation:
we know that
The circumference of a circle is equal to
In this problem we have a 3/4 of a circle
so
the circumference is equal to
we have
substitute
I assume you need the difference between the percentages,
if
132 mil...........................100%
9.2 mil............................x
x=(9.2 mil * 100)/132= 6.96%
142 mil...........................100%
13.4 mil..........................y
y=(13.4 *100)/142= 9.43%
the difference is
9.43-6.96=2.47 %
Answer: 0.75 (choice B)
=============================================
Explanation:
One way to set up the equation is to think of it like this
vertical/horizontal = vertical/horizontal
So we could say
(3.5)/(28) = x/6
Cross multiply and solve for x
3.5*6 = 28*x
21 = 28x
x = 21/28
x = (3*7)/(4*7)
x = 3/4 in fraction form
x = 0.75 in decimal form
-------------
Another possible set up equation is
28/6 = (3.5)/x
in this case I divided the horizontal sides together (28 and 6) and the vertical sides divide to form their own separate fraction as well.
Solving that equation should lead you to x = 3/4 = 0.75
Other equations are possible.
