Answer:
3y=2x-5
Step-by-step explanation:
well y=mx+b
so you do the following
2x+3y=-5
-2x . -2x
3y=2x-5
is this what you need
Answer:
The brainliest!
Step-by-step explanation:
c= 7/6k- 17(7/6)
6/7c = k - 17
k = 6/7c+17
Given:
Miguel's height:
Actual = 5 feet 10 inches
Shadow = 4 feet 2 inches
Tower's height
Actual = x
Shadow = 8 feet 9 inches
First, we need to convert the height into inches to avoid confusion.
1 foot = 12 inches.
Miguel:
5 ft x 12in/ft = 60 inches + 10 inches = 70 inches ACTUAL
4 ft x 12in/ft = 48 inches + 2 inches = 50 inches SHADOW
Tower:
8 ft x 12in/ft = 96 inches + 9 inches = 105 inches SHADOW
Ratio of Actual to shadow:
Miguel: 70 : 50
Tower: x : 105
70 : 50 = x : 105
70*105 = 50x
7350 = 50x
7350 / 50 = x
147 = x
Actual height of the tower is 147 inches or 12 feet 3 inches long.
To check:
Miguel : 70 / 50 = 1.40
Tower : 147 / 105 = 1.40
Answer:
Both cases will give the same price
Step-by-step explanation:
The total purchase that Joshua do will be:
2* $10.98 + 1 * $11.50 + 2* $15.99 = $65.44
Let's compare the price for both scenario
1. If the tax added before discount
taxed price $65.44 * (100+6.5)% =$69.6936
discounted price= $69.6936* (100-20)%= $55.75488
2. If the tax added after the discount
discounted price= $65.44 * (100-20)%= $52.352
taxed price $52.352 * (100+6.5%) = 55.75488
Both prices will be the same since the operation in this calculation is only multiplication.
