and you can do ANYTTHING to be
L=5B
divide both sides by 5
L/5=B
sub L/5 for B in other equation
L+7=3((L/5)+7)
distribute
L+7=(3L)/5+21
minus 7 both sides
L=(3L)/5+14
time boths sides by 5
5L=3L+70
minus 3L both sides
2L=70
divide 2
L=35

Answers
Answer:
Step-by-step explanation:
To figure this out, we must use the scale of the map as a unit.
So we first figure out how many meters are for each centimeter on the map.
" Two fields at a state park are fields are 8 centimeters ap(?)ta state park are 1,000 meters from each other."
Set up the ratio:
Cross multiply:
=
Meaning:
1000/8
==> 125
x = 125
Meaning that for every centimeter there is 125 meters
1cm = 125m

Final answer:
In order to calculate the original cost of a discounted item, you can adjust the discounted price by dividing it by 1 minus the discount percentage. Therefore, using this method, the original cost of a bike which cost $250 after a 60% discount was $625.
Explanation:
The given question refers to a situation where a bike has been bought for $250 after a discount of 60%. In such a scenario, we want to find out the original cost of the bike before the discount was applied.
To get the original price, we will adjust the equation for the discount, which is Original Price = Discounted Price / (1 - Discount Percentage).
Here, replacing the values / variables provided in the question into the equation, we get:
Original Price = $250 / (1 - 0.60) = $250 / 0.40 = $625.
Therefore, the original cost of the bike was $625.

Answer:
It doubles the area.
Step-by-step explanation:
The formula for the area of a triangle is a = bh/2. So, if we plug in the first triangle, you get a = 6. With the second triangle, the height is being doubled. We can represent this with the equation:
4 × 3 × 2/2
Both 2s cancel each other out, leaving us with a = 12. 12/6 is 2. Therefore, doubling the height will ALWAYS double the area.
