Answer:
A = 1100cm^2
Step by step Explanation:
given the dimensions of width and length of the picture are x+20 by 2x-10 and the frame is a constant 5 cm wider from the edge of the picture to the frame, than the area of the frame is defined as (x+30)(2x)-(x+20)(2x-10) = 30x+200.
If the width is equal to the length which I assume is true if the width is constant.
than x+30=2x, which means x = 30.
if this is true than 30(30)+200 = 1100cm^2

Answer:
A)5/8
Step-by-step explanation:
- <em>The range of a set of data is the difference between the highest and lowest values in the set. </em>
<u>Given data set:</u>
<u>Rewriting the data set in the same denominator to compare:</u>
<u>As we see the smallest value is 5/8 and the highest value is 10/8, so the difference:</u>
So, the range of the given data set is 5/8

Answer:
10 years old
Step-by-step explanation:
The difference in ages is 60 -30 = 30 years. When mom was 4 times daughter's age, the difference in their ages was 3 times the daughter's age.
The age difference was 30 years at that time, so the daughter was 10 years old.
