Answer:
2/5 m or 4 dm
Step-by-step explanation:
The fraction 4/10 can be reduced by removing a factor of 2 from numerator and denominator. The length could be expressed as 2/5 m.
The metric system has unit prefixes that make it easy to choose appropriate units for almost any measurement. Apparently Christina wants to use 1/10 m as her unit of measurement. That length is also called a "decimeter." So, Christina's measurement could be expressed in very simple form as 4 dm.
_____
A decimeter is not a particularly common unit in everyday use, though it is reasonably useful for many purposes.* More conventionally, lengths in that range are expressed in centimeters, so Christina's measurement could also be described as 40 cm.
____
* I like units of decimeters for volume calculations, because a cubic decimeter is 1 liter.
Answer:
x = - 
, x = - 1
Step-by-step explanation:
Given
(x + 1)(3x + 4) = 0
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
3x + 4 = 0 ⇒ 3x = - 4 ⇒ x = -
Solutions from least to greatest are
x = - , x = - 1
Answer:
No, he is not correct.
Step-by-step explanation:
0.23 × 2.07 = 0.4761
Multiply 0.23 and 2.07 to get 0.4761.
0.4761=0.04761
Compare 0.4761 and 0.04761.
False
Let x = the price for theater ticket
so, x + 60 = 450
x = 390
there are 15 members in the club so 390/15 = $26 per person
