In converting measurements, we use conversion factors to multiply to the given value. For the first item, the conversion factor would be 5280 ft = 1 mi and 1 min = 60 s. We calculate as follows:
30 ft / s ( 1 mi / 5280 ft ) ( 60 s / 1 min ) = 0.34 mi / min
For the second item, we calculate as follows:
Turtle's speed: 12 mi / hr ( 5280 ft / 1 mi ) ( 1 yd / 3 ft ) (1 hr / 60 min) = 352 yd / min
Boy's speed: 4.4 ft / s ( 1 yd / 3 ft ) ( 60 s / 1 min ) = 88 yd / min
Answer:
6x + 1
3x + 3
6x + 9
Step-by-step explanation:
1)
To find the missing number, compare both sides of the equation. If the variable terms are the same and the constant terms are different, then the equation has no solutions.
2x + 9 + 3x + x = _x +_
6x + 9 = _x + _
6x + 9 = 6x + 1
2)
To find the missing number, compare both sides of the equation. If the variable terms are the different and the constant terms are either different or same, then the equation has one solution.
2x + 9 + 3x + x = _x + _
6x + 9 = _x + _
6x + 9 = 3x + 3
3)
When equation is true for every possible value of x.
To find the missing number, compare both sides of the equation. If the variable terms are the same and the constant terms are same, then the equation has no solutions.
2x + 9 + 3x + x = _x + _
6x + 9 = _x + _
6x + 9 = 6x + 9
6x = 6x +9 -9
6x = 6x
6x/6 = x
x = x
