Im sorry but i dont understand your question. can you be more pacific.
<u>ANSWER: </u>
The length and breadth of the rectangle are 18 m and 12 m.
<u>SOLUTION:
</u>
Let the length and breadth of a rectangle be "l" and "b"
Given,length and breadth of the rectangle are in ratio 3 : 2
Then, length : breadth :: 3 : 2
-- eqn 1
After changing the length and breadth by 1 meter on both sides, length and breadth becomes L+2 and b+2
Now, the ratio of length to breadth is 10 : 7
Length : breadth :: 10 : 7
7l + 14 = 10b + 20
10b – 7l + 20 -14 = 0
10b – 7l + 6 =0 -- eqn (2)
Now, substitute “l” value in (2)
20b – 21b + 12 = 0
-b + 12 = 0
b = 12.
Substitute b value in (2)
10(12) – 7l + 6 = 0
120 + 6 = 7l
7l = 126
l = 18
hence, the length and breadth of the rectangle are 18 m and 12 m.
Answer:
your answer is incorrect thr correct answer is a
550 + 0.05c
Step-by-step explanation:
you are supposed to multiply 1/3 and 1650 then 1/3 * 0.15c
The answer is 70 miles.
If we express distances as following:
T - total distance
a - distance from <span>San Antonio to Austin
b - </span>distance from <span>Austin to Waco
c - </span>distance from <span>Waco to Dallas
Then:
T = 280 mi
b = a - 30 mi </span>⇒ a = b + 30<span>
b = c + 20 mi </span>⇒ c = b - 20<span>
T = a + b + c
</span>⇒ a + b + c = 280
⇒ b + 30 + b + b - 20 = 280
⇒ 3b +10 = 280
⇒ 3b = 280 - 10
⇒ 3b = 270
⇒ b = 90 mi.
Distance from <span>Waco to Dallas is c.
</span><span>c = b - 20
</span>⇒ c = 90 - 20
⇒ c = 70 mi
Therefore, distance from <span>Waco to Dallas is 70 miles.</span>
