Answer:
Property of equality division
Step-by-step explanation:
Given
c = d
b ≠ 0 then c∕b = d∕b
Required
State the property used
From list of options a through d, only option A best fits the description.
This is so because property of equality division is such that
given two variables c and d where c = d
Provided that b ≠ 0
Take for instance;
b = 2; c = 8 and d = 8;
This implies that
Divide both sides by 2 (assumed value of b)
<span>-1/9 - (-2/15)
= </span>-1/9 +2/15<span>
= -5/45 + 6/45
= 1/45</span>
Answer:
9.5 feets
Step-by-step explanation:
Length of drawing = 8 4/9 inches
Scale : 1/3 inch in drawing = 3/8 actual length
Length of drawing / drawing scale
8 4/9 = 76/9 inches
Number of 1/3 inches in total length of drawing :
76/9 ÷ 1/3
76/9 * 3 / 1
(76*3) /(9*1) = 228 /9 = 9 3/9 = 9 1/3
9 1/3 * 3/8 foot
(228 / 9) * (3 /8)
(228/3) * (1/ 8)
228 / 24
= 9.5 feet
Answer:
Rs 8500
Step-by-step explanation:
For a cost price of c, the marked price is ...
marked = c +25%·c = 1.25c
After the 15% discount, the sale price will be ...
s = marked -15%·marked = 0.85·marked = (0.85)(1.25c) = 1.0625c
The profit will be the difference between the sale price s and the cost c:
p = s -c
500 = (1.0625c) -c = 0.0625c
Then the cost is ...
500/0.0625 = c = 8000
and the sale price is ...
s = c +p = 8000 +500 = 8500 . . . rupees
The selling price will be Rs 8500.
