Another expression that is equivalent to 7/2h-3(5h-1/2) is -23/2h+3/2
Answer:
30%
Step-by-step explanation:
One simple way of finding out discounts is to simplify our answer by starting with 10% and subtracting from that.
If the original price were to have a 10% discount, it would be 4.70/10 for .47 per 10% off.
10% gives us 4.23, so let's take another 10% off by doing 4.23-.47, which is equal to 3.76. While lower, it's not our answer so lets do another 10%
3.76-4.7 = $3.29
With a total of 3 10%'s taken off, or in this case, 30% off, we can conclude that the discounted prices of $3.29 is 30% of the original price.
Step-by-step explanation:
-3x-9
divide the equation by -1 so that the -1's are taken from -3x and -9. so the -1 goes on the outside of 3x+9
-1(3x+9)
then divide the equation by 3 since 3x and 9 is divisible by 3.
(-1)(3)(3/3x+9/3)
-3(x+3)
Now we can expand again to check the problem
-3 times x=-3x
-3 times 3=-9
and add
-3x-9
Hope that helps :)
Answer: 0.99
Step-by-step explanation:
SOH CAH TOA
CAH: cosine = adjacent/hypotenuse
Cosine of angle w = 84/85 = 0.98823 ≈ 0.99
Angle Y is 90 degrees, meaning it's a right triangle. Therefore angle W is the top/tip of a triangle, while X is the angle next to Y. If you plug in the information afterwards and follow the trigonometry rule (SOH CAH TOA) you will find your answer.
