Answer:
x = 14
Step-by-step explanation:
The sum of the interior angle of a regular polygon is 540 degrees
Since the interior angles are 5, then;
5(9x - 18) = 540
Expand the bracket
5(9x) - 5(18) = 540
45x - 90 = 540
45x = 540 + 90
45x = 630
x = 630/45
x = 14
Hence the value of x is 14
What is the equation of the line in slope-intercept form?
Answer:
y=-5x+6
Step-by-step explanation:
To find your slope (or m value), you must identify 2 points that your line crosses through (I used (1,1) and (0,6). You can either count up and over to the point (0,6) from (1,1), or you can use the formula y2-y1/x2-x1 (it would look like 6-1/0-1). This will give you -5 for your slope.
Your x-intercept (or b value) is 6 because you can see from the graph that that is where your line intercepts y.
I hope this helped :)

A store is having a sale on trail mix and jelly beans. For 5 pounds of trail mix and 3 pounds of jelly beans, the total cost is $18. For 2 pounds of trail mix and 12 pounds of jelly beans, the total cost is $45. Find the cost for each pound of trail mix and each pound of jelly beans.
The cost for each pound of trail mix is $1.5 and each pound of jelly beans is $3.5 .
What is elimination method?The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.
According to the question
A store is having a sale on trail mix and jelly beans .
Let trail mix = T
and jelly beans = J
For 5 pounds of trail mix and 3 pounds of jelly beans, the total cost is $18.
i.e
5T + 3J = 18 -------------------------- (1)
For 2 pounds of trail mix and 12 pounds of jelly beans, the total cost is $45.
i.e
2T + 12J = 45 -------------------------------(2)
Now,
multiplying eq (1) from 4
20T + 12J = 72 -----------------(3)
Solving equation (3) and (2) the equation by elimination method
20T + 12J = 72 -----------------(3)
2T + 12J = 45 -------------------------(2)
subtracting equation (2) from (3)
18T = 27
T = 1.5
substituting the value of T in equation 1
5T + 3J = 18
5*1.5 + 3J = 18
7.5 + 3J = 18
3J = 18 - 7.5
3J = 10.5
J = 3.5
Hence, the cost for each pound of trail mix is $1.5 and each pound of jelly beans is $3.5 .

you pick a card, roll a die, and find the sum. How many different sums are possible?
If we pick a card, roll a die, and find the sum , the different sums possible is 17.
What is Permutation and Combination ?A permutation is an act of arranging the objects or numbers in order.
Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.
If we pick any card and roll a die
The sum possible is
The highest it can be would be 13(card) + 6(die) =19
the Lowest it can be would be 1(card) + 1 (die) = 2
So the different sums possible is 19-2 = 17.

9514 1404 393
Answer:
1414 cm³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
For a radius of 5 cm and a height of 8 cm, the volume is ...
V = π(5 cm)²(18 cm) = 450π cm³ ≈ 1414 cm³
The volume of Nadia's sugar container is about 1414 cm³.
