Answer:
10:40
Step-by-step explanation:
3x4 = 12
4 x 4 = 16
5 x 4 = 20
so 10 x 4 = 40 (10:40)
To estimate an answer to this problem, you must first estimate the numbers as well. 189 would round to 190, and 643 would round to 640. Now you would subtract 190 from 640, giving you 460.
The movie rate is going to be about 2 or 3 percent
Answer:
2
Step-by-step explanation:
x2+3x=6
Step 1: Subtract 6 from both sides.
x2+3x−6=6−6
x2+3x−6=0
For this equation: a=1, b=3, c=-6
1x2+3x+−6=0
Step 2: Use quadratic formula with a=1, b=3, c=-6.
