Answer:
y=0.3x
Step-by-step explanation:
Formula =
y α x
y = kx
Where k is the constant of proportionality.
When y = 1.5; x = 5;
We substitute these known values in the equation,
y = kx
1.5 = k5
Dividing both sides of the equation by 5 to find the value for k, we have
1.5/5= k0.3/5
Therefore,
K = 0.3
Having found the value of k,
We substitute this value into the relationship
y = kx
Therefore we have,
y = 0.3x.
The direct variation function is therefore,
y = 0.3x.

Answer:
The number of pages had Clint read prior to study hall were <u>127 pages</u>.
Step-by-step explanation:
Given:
Clint after 20 minutes is on page 151.
And, after 45 minutes he is on page 181.
Now, to find the pages Clint read prior to study hall.
<em>The time difference = 45 minutes - 20 minutes.</em>
<em> = 25 minutes.</em>
<em>Difference between the pages = 181 - 151</em>
<em> = 30 pages.</em>
If Clint is reading each page at same speed.
Then, in 25 minutes he can read = 30 pages.
So, in 1 minute he can read = 30 ÷ 25 = 1.2 pages.
Thus, in 20 minutes he can read
Now, number of pages Clint had read prior to study hall = 151 - 24
= 127 pages.
Therefore, the number of pages had Clint read prior to study hall were <u>127 pages</u>.
