The property the applies only to addition and multiplication is the commutative property. It means that the numbers can be arranges in any order. so for example you will get the same answer whether you do
5+6 or 6+5
Answer:
24*2-8+4^2/8-6=36 #markasbrainliest
Natasha got the power right. The power is 295 hp.
<h3>How to calculate power?</h3>
t = 5.825∛w / p
where,
- w = weight of the car
- p = power delivered by the engine in horsepower
- quarter mile time = t
Therefore,
t = 13.4 s
p = 3590
13.4 = 5.825∛ 3590 / p
cube both sides
13.4³ = 5.825³ × 3590 / p
2406.104 = 197.645890625 × 3590 / p
cross multiply
2406.104 p = 709548.747344
p = 709548.747344 / 2406.104
p = 294.895294361
p = 295 hp
Therefore, Natasha got the power right

Answer:
(2, 1)
Step-by-step explanation:
The best way to do this to avoid tedious fractions is to use the addition method (sometimes called the elimination method). We will work to eliminate one of the variables. Since the y values are smaller, let's work to get rid of those. That means we have to have a positive and a negative of the same number so they cancel each other out. We have a 2y and a 3y. The LCM of those numbers is 6, so we will multiply the first equation by a 3 and the second one by a 2. BUT they have to cancel out, so one of those multipliers will have to be negative. I made the 2 negative. Multiplying in the 3 and the -2:
3(-9x + 2y = -16)--> -27x + 6y = -48
-2(19x + 3y = 41)--> -38x - 6y = -82
Now you can see that the 6y and the -6y cancel each other out, leaving us to do the addition of what's left:
-65x = -130 so
x = 2
Now we will go back to either one of the original equations and sub in a 2 for x to solve for y:
19(2) + 3y = 41 so
38 + 3y = 41 and
3y = 3. Therefore,
y = 1
The solution set then is (2, 1)
16,400,000 - 3,900,000 = 12,500,000
