<span>Divide the first term of the numerator by the first term of the denominator, and put that in the answer.Multiply the denominator by that answer, put that below the numerator.Subtract to create a new polynomial.
Hope this helps. :)

Answer:
The answer is (x,y)=(-10,-7)
Step-by-step explanation:
- The solution comes from replace x= -10 into the equation of y=2/5 x -3.
- Replacement of x= -10 into y = 2/5 x -3 results:
.
Answer:
1. 625,000 J
2. 100 J
4. 5 kg
5. √5 ≈ 2.236 m/s
Step-by-step explanation:
You should be aware that the SI derived units of Joules are equivalent to kg·m²/s².
To reduce confusion between <em>m</em> for mass and m for meters, we'll use an <em>italic m</em> for mass.
In each case, the "find" variable is what's left after we put the numbers into the formula. It is what the question is asking for. The "given" values are the ones in the problem statement and are the values we put into the formula. The formula is the same in every case.
__
1. KE = (1/2)<em>m</em>v² = (1/2)(2000 kg)(25 m/s)² = 625,000 kg·m²/s² = 625,000 J
__
2. KE = (1/2)<em>m</em>v² = (1/2)(0.5 kg)(20 m/s)² = 100 kg·m²/s² = 100 J
__
4. KE = (1/2)<em>m</em>v²
250 J = (1/2)<em>m</em>(10 m/s)² = 50 m²/s²
(250 kg·m²/s²)/(50 m²/s²) = <em>m</em> = 5 kg
__
5. KE = (1/2)<em>m</em>v²
2000 kg·m²/s² = (1/2)(800 kg)v²
(2000 kg·m²/s²)/(400 kg) = v² = 5 m²/s²
v = √5 m/s ≈ 2.236 m/s
Hello!
Here's how much each person stacked:
Ronnie -- 0.25 of the 40 pizzas.
Mack -- 9/40
Kim -- 35% of the 40 pizzas.
Ada -- rest of the pizzas.
Now, the questions asks for who stacked the most pizzas.
First, find our how many pizzas they stacked out of 40.
40 × 0.25 = 10
40 × 35% = 14
10 + 9 + 14 = 33
40 - 33 = 7
This means that Ronnie stacked 10 pizzas, Mack stacked 9 pizzas, Kim stacked 14 pizzas, and Ada stacked 7 pizzas.
ANSWER:
Kim stacked the most pizzas since she stacked 14 of them.
