Answer:
x=9
Step-by-step explanation:
Add similar elements: -5x+3x=-2x
-2x+15=-3
Subtract 15 from both sides
-2x + 15-15=-3-15
Simplify
-2x=-18
Divide both sides by -2
-21/-2 = -18/-2
Simplify
x=9
Answer:
300K
Step-by-step explanation:
T = t + 273 °C
T is absolute temperature
t = given temperature (27°C in this case)
Hence T = 27 °C + 273 °C (standard temperature)
T = 300K (since absolute temperature is measured in K from the question's preamble)
Answer:
AAS Theorem
Step-by-step explanation:
we can see that
angle ZVY ≅ angle WVY
angle VZY ≅ angle VWY
side VY shared by both triangles.
by Angle- Angle- SIde (AAS), the triangles are congruent.
Answer:
I thin’ the answer is D
You would put 80 x
—- = ——
250 100
So those are fractions^
The first thing you do here is cross-multiply. (It doesn’t matter which sides you multiply together first)
So 250 times x= 250x
Then cross multiply 80 and 100 to get:
8,000
You now have ur new equation:
250x=8,000
The next thing you do here is divide both sides by 250, since 250 is the number with a variable in it (aka “x”)
You then get:
32 students as you’re final answer.
I hope that helped you understand !
