An equivalent statement is CD overbar congruent to EF overbar.
What is a line segment?
The line segment has two fixed-length endpoints, A and B. The distance between this line segment's endpoints A and B is its length.
Here,
Line segment CD is congruent to line segment EF and in geometry, an overbar represents a line segment.
So, we can say that the CD overbar means line segment CD and the EF overbar means line segment EF.
Hence, An equivalent statement is CD overbar congruent to EF overbar.

Solving a system of equations we will see that we need to use <u>40 liters of the 80% acid solution</u>, and the other <u>20 liters are of the 35% acid solution</u>.
<h3>
How many liters of each solution do we need to use?</h3>
First, we need to define the variables:
- x = liters of the 35% acid used.
- y = liters of the 80% acid used.
We know that we want to produce 60 liters of 65% acid, then we have the system of equations:
x + y = 60
x*0.35 + y*0.80 = 60*0.65
(in the second equation we wrote the percentages in decimal form).
To solve this we need to isolate one of the variables in one equation and then replace it in other one, isolating x we get:
x = 60 - y
Replacing that in the other equation:
(60 - y)*0.35 + y*0.80 = 60*0.65
y*(0.80 - 0.35) = 60*(0.65 - 0.35)
y*0.45 = 60*0.30
y = 60*0.30/0.45 = 40
So we need to use <u>40 liters of the 80% acid solution</u>, and the other <u>20 liters are of the 35% acid solution</u>.

16 oz = 1 lb
Step-by-step explanation:
9.375 lb = 150 oz
Answer:
9.375 lb
150 oz
its d or e
Answer:
15
Step-by-step explanation:
determine the numerical length of AC
We know that Ac is equaled to ab and bc because they are the segements between ac
3x 4x+8
A-----------------------------B----------------------------------C
|<----------------------------5x+10 --------------------------->|
AB + BC = AC
solving for x
3x + 4X + 8 = 5X + 10
3x+4x-5x= 10-8
2x=2
x=1
Now sub that in for ac
AC= 5x +10
AC= 5(1) +10
AC= 5 +10
AC = 15
