Answer:
3 a : 2 b = 6 : 1
Step-by-step explanation:
<em>
= 
</em>
<em>3 ( a + b) = 5 ( a - b)
</em>
<em>3 a + 3 b = 5 a - 5 b
</em>
<em>5 b + 3 b = 5 a - 3 a
</em>
<em>
8 b = 2 a
</em>
<em>
2 a = 8 b</em>
<em><u>a = 4 b</u></em>
<em>3 a = 3 × 4 b</em>
<em><u>3 a = 12 b</u></em>
<em>3 a: 2 b = 12 b : 2 b</em>
<em>3 a : 2 b = 6 : 1</em>
Answer:
$2250
$2430
Step-by-step explanation:
If the seller made a profit of 20%, it means he sold the television at a price that is 20% higher than the cost price. That means that the sales price is 1.2 times higher than the cost price
let t = cost price of the television
the following equation can be derived
1.2 x t = $2700
divide both sides by 1.2
t = $2250
If there is a 10% discount, the television is (100 - 10%) 90% cheaper
0.9 x 2700 = $2430
Answer:
Step-by-step explanation:
Consider the below figure attached with this question.
Given information: a∥b, 
.
a∥b (Given)
(Given)
Multiply both sides by 8.
...(1)
If a transversal line intersect two parallel lines then the same sided interior angles and are supplementary angles.
(Same sided interior angles)
(Substitution)
Divide both sides by 9.
The measure of angle 6 is 20 degree.
Substitute this value in equation (1).
The measure of angle 4 is 160 degree.

It will take 60 seconds. Because they went in at the first floor and ran up to the third in 30 seconds, if they go down and go up to the 6th floor it would be a minute, because 30+30 is 60
