Of means multiply
is means equals
1/2 • x = -.25
Rewritten
.5•x=-.25
Inverse operations to isolate the variable.
x = -.25/.5
x = -.5
The inequality that is true is 7π > 21
<h3>How to determine the inequality that is true?</h3>
To do this, we simply test the given inequalities (starting from the first)
The first inequality is represented as
7π > 21
Divide both sides of the inequality by 7
So, we have:
7π/7 > 21/7
Evaluate the quotient of 21 and 7
So, we have:
7π/7 > 3
Evaluate the quotient of 7π and 7
So, we have:
π > 3
The above inequality is true.
This is so because π = 3.14 and 3.14 > 3
Hence, the inequality that is true is 7π > 21

C im pretty sure thats it
Answer:
y=6.2 and x=0.4 or (0.4,6.2)
Step-by-step explanation:
Since both expressions are equal to y, we can set them equal to each other and solve for x:
3x+5=8x+3
5=5x+3
2=5x
2/5=x
0.4=x
Now to solve y:
y=8(2/5)+3
y=16/5+3
y=3.2+3
y=6.2
Check answers:
6.2=3(0.4)+5
6.2=1.2+5
6.2=6.2
6.2=8(0.4)+3
6.2=3.2+3
6.2=6.2
Answers work, so y=6.2 and x=0.4 or (0.4,6.2) as an ordered pair
Because AB is a midsegment, the length of AB is half he length of XZ so basically you do
2(3x-1)=34.
Divide 2 by both sides to get 3X-1=17
Add 1 to boh sides to get 3X=18
Divide 3 from boh sides to get X=6
Hope this helps :)
