Answer:
Total laps = 10d
Step-by-step explanation:
Let c = Carl's laps
d = Daria's laps
e = Erin's laps
c = 3d
c = e/2
c + d + e = totals laps
We can insert 3d in place of c in the third equation
3d + d + e = total laps
Also, e/2 equals 3d
e/2 = 3d
Multiply both sides by 2
(e/2 = 3d)2
e = 6d
Insert the new e
3d + d + 6d = 10d = totals laps
Answer:
If the scale factor is represented by , then the area of the scale drawing is
times the corresponding area of the original drawing.
Step-by-step explanation:
If the scale factor is represented by , then the area of the scale drawing is
times the corresponding area of the original drawing.
For example:
<em>Given a scale factor of 25%, would the quotient of the area of the scale drawing to the area of the original drawing be? </em>
<u>Answer:</u>
The quotient of the areas would be equal to the square of the scale factor. Therefore, the quotient of the scale drawing to the original in this example would be equal to
Hope it will find you well.
1 2/3 = 5/3
2 3/4 = 11/4
5/3 ÷ 11/4 = 5/3 × 4/11
= 20/33
This would be the correct answer
Answer:
3
Step-by-step explanation:
Step 1. Substitute all the letters for their values and since in algebra when you don't write the times sign it means you wanna times it so what you would do is 3 x 3 x 5 x 2 = 90.
Step 2. Substitute the <em><u>a</u></em> in 10a for 3 then times since there is a "hidden" times symbol. Which then would be 10 x 3 = 30
Step 3. When we say something over something it means to divide so what we do is divide the first answer by the second answer which is: 90/30 which is 3.
Hope this helps, and if you need further explanation I can do so. :)
