Answer:
10 days
Step-by-step explanation:
Jenny has read 50 pages and will read 15 each day.
The equation would be: 15x+50
Mark will read 20 pages daily.
The equation would be: 20x
In both equations x represents days.
You set both equal to each other because you want to know when they read the same amount of pages.
15x+50=20x
...you subtract 15x from both sides
50=5x
...and divide by five to get: 10 days
Answer:
both are equal is 0
Step-by-step explanation:
After substituting, the answer is 0 to both
Scale factor is simply the ratio of sides of two corresponding figures
<em>The estimated scale factor is 1.5</em>
From the question, we have:
- The actual figure is AB
- The dilation is AC
- The center of dilation is A
So, the scale factor (S) would be:
The actual measurements are not given; so, we will make use of estimates
The estimates to use are:
So, the scale factor is:
Hence, the estimated scale factor is 1.5
