Add all the sides together or multiply two sides.
Answer:
3x + y = 20
Step-by-step explanation:
The equation of line passing through two points is determined by formula:
Here, (x₁ , y₁) = (4, 8)
and (x₂, y₂) = (6, 2)
Putting these value in above formula. We get,
⇒
⇒ ( y - 8) = -3 (x - 4)
⇒ y - 8 = -3x + 12
⇒ 3x + y = 20
which is required equation.
S--------T--------U
ST = T U
SU = 10
ST + TU = SU
3x + 7x = 10
10x = 10
x = 10/10
x = 1
So, what do you think happens next?
ST = 3x
Let x = 1
ST = 3(1)
ST = 3
I hope this helps.
Answer:
try multiplication
Step-by-step explanation:
Carol's answer is incorrect because you must find the same denominator.
Eliana's answer is incorrect. If you look at the end she say 12/8=3/4
Clearly 12/8=6/4=1.5
