Vlada [557]3 years ago

Answer:

x = 3

y = 2

Step-by-step explanation:

When 2 triangles are congruent, they will have exact same 3 sides length and exact same 3 angles measure.

So we can say:

-2x + 6y = 6

and

-7x + 8y = -5

Let's multiply first equation by 7 and 2nd equation by -2, to get:

7 [-2x + 6y = 6] = -14x +42y = 42

and

-2 [-7x + 8y = -5] = 14x - 16y = 10

Now adding these 2 new equations and solving for y:

-14x +42y = 42

14x - 16y = 10

----------------------

26y = 52

y = 52/26

y = 2

Now we put y = 2 into 1st equation (or any other) and solve for x:

-2x + 6y = 6

-2x + 6(2) = 6

-2x + 12 = 6

6 = 2x

x = 6/2

x = 3

Pani-rosa [81]

Answer:

D.  \frac{285}{12.5} and \frac{295}{11.5}.

Step-by-step explanation:

We have been given that one a recent trip, Cindy drove her car 290 miles, rounded to the nearest 10 miles, and used 12 gallons of gasoline, rounded to the nearest gallon.

The range of miles driven would be between 285 because number of miles in rounded to nearest 10 miles.

The range of gallons of gasoline would be 11.5 because number of gallons of gasoline in rounded to nearest gallon.

To find mileage, we will divide number of miles by number of gallons.

The possible number of gallons of gasoline will be 12.5 gallons for 285 miles to get the minimum number of miles.

Similarly, the possible number of gallons of gasoline will be 11.5 gallons for 295 miles to get the maximum miles.

Therefore, our required range would be \frac{285}{12.5} and \frac{295}{11.5}.

When a fish is selected at random from a tank, the probability that it has a green tail is 0.36, the probability that it has red
Katarina [22]

Answer: 0.26

Step-by-step explanation:

As per given , we have

P(green tail) = 0.36

P(red fins) = 0.59

P(both a green tail and red fins ) = 0.21

Now, P(Neither red fin nor green tail )= 1 - P(either red fin or green tail )

<em>[P(neither A nor B)= 1- P(either A or B)]</em>

= 1-(P(green tail) +P(red fins)+P(both a green tail and red fins ))

<em>[P(A or B)= P(A)+P(B)-P(A and B)]</em>

= 1- (0.36+0.59-0.21)

= 1-(0.74)

= 0.26

Hence, the probability that the selected fish will not have a red fin or a green tail = 0.26
