Answer: 51
Step-by-step explanation:
let x be the number.
(70%)x = 42
0.7 x = 42
x = 60
we check 15% x 60 = 0.15 x 60 = 9, which is true.
85% of that number = 85% x 60 = 0.85 x 60 = 51.

Answer:
<h2><em><u>162</u></em><em><u>0</u></em><em><u> </u></em><em><u>words</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>,</u></em><em><u> </u></em>
Number of words Lucy can type in 5 minutes
= 300 words
<em><u>So</u></em><em><u>,</u></em>
Number of words Lucy can type in 1 minute

= 60 words
<em><u>Therefore</u></em><em><u>,</u></em><em><u> </u></em>
Number of words Lucy can type in 27 minutes
= (60 × 27) words
= 1,620 words
<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em><em><u>Lucy</u></em><em><u> </u></em><em><u>can</u></em><em><u> </u></em><em><u>type</u></em><em><u> </u></em><em><u>162</u></em><em><u>0</u></em><em><u> </u></em><em><u>words</u></em><em><u> </u></em><em><u>in</u></em><em><u> </u></em><em><u>27</u></em><em><u> </u></em><em><u>minutes</u></em><em><u>.</u></em><em><u> </u></em>

==================================================
Explanation:
w = width
w-4 = length since it is 4 less than the width
Multiply the length and width to get the area of the rectangle.
area = length*width
area = 
area = 
area = 
In the last step, I used the distributive property.
Either expression mentioned above is valid for the area. If you had to pick only one, I'd go for
