\text{Hello there!}\\\\\text{Solve for x:}\\\\7(x -3)=4(x+5)\\\\\text{Distribute the 7 to the variables inside the parenthesis}\\\\7x-21=4(x+5)\\\\\text{Distribute the 4 to the variables inside the parenthesis}\\\\7x-21=4x+20\\\\\text{Subtract 4x from both sides}\\\\3x-21=20\\\\\text{Add 21 to both sides}\\\\3x=41\\\\\text{Divide both sides by 3}\\\\x=41/3\\\\\boxed{\text{x = }\frac{41}{3}}}

Suppose you have a 6-face unfair dice with numbers 1,2,3,4,5,6 on each of its faces. If the probability distribution of throwing
kotegsom [21]

Answer:

D is correct

Step-by-step explanation:

Here, we want to select which of the options is correct.

The correct option is the option D

Since the die is unfair, we expect that the probability of each of the numbers turning up

will not be equal.

However, we should also expect that if we add the chances of all the numbers occurring together, then the total probability should be equal to 1. But this does not work in this case;

In this case, adding all the probabilities together, we have;

1/12 + 1/12 + 1/12 + 1/12 + 1/12 + 1/2

= 5(1/12) + 1/2 = 5/12 + 1/2 = 11/12

11/12 is not equal to 1 and thus the probability distribution cannot be correct

How might a change in the environment affect plants differently than it would animals?
valentina_108 [34]

Answer:

Some plants need certain things in their environment, so if their environment changes it could make the plants not grow. Animals would most likely either move to a different area or would get used to the change.

The tension t in a spring varies directly with the distance d the spring is stretched. If the
yarga [219]

Answer:

t = 21d

Step-by-step explanation:

Here tension and distance are denoted t by d  and  respectively. Since  t varies directly with d , then the relation between  t and d is k=td Given that, for the tension 42 pounds, the spring is stretched 2 inches. Substituting  t = 42 and d= 2 into  t = kd find the value of k . Therefore,

42= K (2)

K=\frac{42}{2}

K= 21

Thus the relationship is t = 21d
