5 1/4 - 3 3/4 = 4 5/4 - 3 3/4 = 1 2/4
Answer is the third one or C. Can I have brainliest?! Please?!
Answer:
10⁴ seconds
Step-by-step explanation:
Given that,
A person breathes
in about cubic meters of air per second.
We need to find time taken to breathe 2.5 cubic meters of air.
In 1 sec =
m³ of air breathe
Let in x seconds, 2.5 m³ of air taken by the person.

Hence, in 10⁴ seconds 2.5 m³ of air is taken by the person.

<h3>Answer : y = ⅚x - 3</h3>
════════════════════
<h3>Known</h3>
x1 = 6
y1 = 2
x2 = (-6)
y2 = (-8)
════════════════════
<h3>Question</h3>
Equation of the line (y = mx + c)
════════════════════
<h3>Way to do</h3>
#First, you find the gradient (m)

#Now use the formula of equation of the line
y - y1 = m(x - x1)
y - 2 = ⅚(x - 6)
y - 2 = ⅚x - 5
y = ⅚x - 5+2
y = ⅚x - 3
