Answer:
the answers are:x1=-4 and x2=5
5x + 4x = 720
9x = 720 (divide by 9)
X= 80
In order to get the bigger ratio, which is 5, you would substitute x for 80. (I'm bad at explaining)
Work:
5(80)= 400
10 30 45 45 48 55, 55-10=45=mode median and mean
Hope this helps
Answer:
x≥1 or x≤−3
Step-by-step explanation:
x+1≥2 possibility 1
x+1−1≥2−1 Subtract 1 from both sides
x≥1
x+1≤−2 Possibility 2
x+1−1≤−2−1 Subtract 1 from both sides
x≤−3
She is not correct, because $3.00 divided by 6 is 50 cents, so by using that equation she could evaluate that she is wrong and find the correct answer.
