3 0

You can fill the second in in the first to get an equation with only b:

(b-2) - 3b = 22 =>

-4b-2 = 22 =>

-4b = 24

b = -6

a = -6-2 = -8

So (-8,-6) is the answer.

A bag contains 12 pieces of candy, all the same size. Four of the candies are lemon flavored. Which approach would be best to fi

igor_vitrenko [27]

Answer: Relative frequency approach

Step-by-step explanation:

In relative frequency of an event is defined as the number of times that the event occurs during experimental trials, divided by the total number of trials conducted in the given event.

That is if there are total 9 boys in which 4 are from Us.

Then the probability of choosing a boy of Us= Number of boys from US/ total number of boys= 4/9

In our question, we have total pieces of candy= 12

In which lemon-flavored piece of candy = 4

the probability of randomly drawing a lemon-flavored piece of candy= 4/12

= lemon-flavored piece of candy/ total pieces of candy

Thus, we are using relative frequency approach for finding the probability.

Therefore, Option C is correct.

An isosceles triangle has an angle that measures 94º. Which other angles could be in that

Nataly [62]

Answer:

43°

Step-by-step explanation:

In a isosceles triangle, two angles HAVE to be equal.

This means that 94 can be one of the angles that are equal, or the angle that is not equal to another angle.

Let's start with the fact that 94 can be one of the angles that are equal. (Note: angles in a triangle add up to 180)

94+94+x=180

188+x=180

There is NOT a possible value for x in this situation, as you cannot have a negative value of an angle. Therefore we must try the other situation where 94 is the angle that is not equal to another angle.

x+x+94=180

2x+94=180

Subtract 94 from both sides

2x=86

Divide both sides by 2

x=43

Therefore the answer is 43°
