Áp dụng tính chất của đường trung bình ta có:
20+x=2.(2x+22)
20+x=4x+44
X-4.x=44-20
-3.x=24
X=24/-3x=-8
Trong độ dài ko có độ âm nên tất cả đại lượng hình học đều mang dấu (+) vì vậy kết quả cuối cùng sẽ là 8

Answer:
Bow ties: 1/5
Cheese sauce: 1/4
Bow ties with cheese sauce: 1/20
Step-by-step explanation:
There are 3 different questions here.
First, you have the pasta question. What is the probability you'll end up with bow ties? Well, there are 5 kinds of pasta, all with the same chance to be chosen... so you have 1 chance out of 5 to pick bow ties.
Then the sauce. Same logic... 4 different sauces... so 1/4 chance to get the cheese sauce.
For the bow ties and cheese sauce combo, it's a bit different, we're talking about compound probabilities here.
So, you have to multiply the probability to get bow ties with the probability to get cheese sauce, so:
Answer:
x=2
Step-by-step explanation:
Let's solve your equation step-by-step.
Step 1: Simplify both sides of the equation.
12=2x+4x
12=(2x+4x)(Combine Like Terms)
12=6x
12=6x
Step 2: Flip the equation.
6x=12
Step 3: Divide both sides by 6. 6x/6=12/6
x=2
