Answer:
Take the original price and divide it by .75.
Step-by-step explanation:
If he cost today is $25, which is the result of a 75% sale, this represents 1/4 of the original price. 1/4 is equal to .25. Take the original prices, and divide by .25.
One example is if the sneakers are $25 today, what was the original price?
$25/.25 = $100
Proof:
100 - (100 * 75%) = 100 - 75 = $25.00
Hope this helps! Have an Awesome Day!! :-)
Answer: y = -3x + 6
Step-by-step explanation:
6x + 2y - 6x = 12 - 6x
÷2 (2y = 12 - 6x) ÷2
y = -3x + 6
Answer:
x > -1
Step-by-step explanation:
<u>Step 1: Distribute</u>
3(3x + 7) > 4 - 8(4 + 5x)
(3 * 3x) + (3 * 7) > 4 + (-8 * 4) + (-8 * 5x)
9x + 21 > 4 - 32 - 40x
<u>Step 2: Combine like terms</u>
9x + 21 > 4 - 32 - 40x
9x + 21 > -28 - 40x
<u>Step 3: Add 40x to both sides</u>
9x + 21 + 40x > -28 - 40x + 40x
49x + 21 > -28
<u>Step 4: Subtract 21 from both sides</u>
49x + 21 - 21 > -28 - 21
49x > -49
<u>Step 5: Divide both sides by 49</u>
49x / 49 > -49 / 49
<em>x > -1</em>
Answer: x > -1
Answer:
81.3 feet
Step-by-step explanation:
A shark is swimming 28 feet below sea level. If the angle of depression from a boat on the water is 19 degrees What is the distance between the boat and the shark?
We solve the above question using Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = Angle of depression = 19°
Distance between the boat and the shark = Adjacent = ? = x
Opposite = 28 feet
Hence:
tan 19 = 28/x
Cross Multiply
tan 19 × x = 28
x = 28/tan 19
x = 81.317904575 feet
Approximately = 81.3 feet
The distance between the boat and the shark is 81.3 feet
