Answers

Answer:1/24

Step-by-step explanation:

Since the first die has 4 distinct numbers, and second has 6 distinct numbers, so total number of combinations possible = 4 × 6 = 24

Now, the number of chances where we get the rolling sum as 12 is only one. (

What is the solution of this linear equation system? y = 3x-2 y-2 = x

Answers

Answer:

(2,4)

Step-by-step explanation:

Replace all occurrences of  y  with  3 x − 2  in each equation.

3x - 4 = x

y= 3x -2

Solve for  x  in the first equation.

x = 2

y = 3x - 2

Replace all occurrences of  x  with  2  in the equation.

y = 4

x= 2

The solution to the system is the complete set of ordered pairs that are valid solutions.

Answers

Answer:

Number of cups of lemonade = 59 cups

Step-by-step explanation:

Given the linear function :

C = 2t - 89

At temperature of 74° ;

The cups of lemonade as calculated using the linear model:

C = 2t - 89 ; where c = cost of lemonade ; t = temperature.

C = 2(74) - 89

C = 148 - 89

C = 59

A function assigns the values. The prediction that she will sell 40 cups of lemonade that day is wrong.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

As it is given that function, c=2t-89, where the number of cups of lemonade is represented by c, and t represents the temperature of the day.

Now, as it is given that the temperature at the day is 74, therefore, the number of cups that will be sold that day can be predicted as,

[tex]c = 2t-89\\\\c = 2(74)-89\\\\c = 148-89\\\\c = 59[/tex]

Hence, the prediction that she will sell 40 cups of lemonade that day is wrong.

The measures of the angles of a triangle are shown in the figure below. Solve for x.

Answers

X=27 because all the angles inside a triangle add up to 180°. So you take 180 and subtract 63 and 90 from the to find out the last/missing angle.

Answer: 27°

Step-by-step explanation: Here, we're asked to find the missing angle measure in the triangle shown which is represented by the variable x.

To find the value of x, remember that the sum of the

measures of the angles in a triangle is 180°

So we can setup the equation 63 + 90 + x = 180.

Remember that a box indicates a 90° angle.

Now to solve for x, let's first simplify on the left side of the equation.

63 + 90 is 153 so we have 153 + x = 180.

Now to get x by itself, we subtract 153 from both sides of the equation.

On the left side of the equation, 153 - 153 cancels out and we have x

and on the right side of the equation, 180 - 153 is 27.

This means that the missing angle in the triangle is 27°.
