The angle next to the angle 5x is 180 - 5x
All angles sum to 360
(6x - 58) + (2x + 4) + (180 - 5x) = 180
3x + 126 = 180
3x = 54
x = 18
For question 10, sum of angles in pentagon is 540 degrees
x + 105 + 85 + 114 + 126 = 540
x + 430 = 540
x = 110
The subtraction property of equality: if we subtract one side of the equation then we also must subtract from the other side of the equation.
The division property of equality: if we divide one side of the equation by a number then we also must divide the other side by the same number.
For this equation:
3 x + 5 = 26
3 x + 5 - 5 = 26 - 5 ( the Subtraction Property of Equality )
3 x = 21
3 x : 3 = 21 : 3 ( the Division Property of Equality )
x = 7
Answer: C ) The standard method for solving an equation like 3 x + 5 = 26 is to use the Subtraction Property of Equality and then the Division Property of Equality.
Well, what you're going to do is.. turn 3 1/2 into an irregular fraction.
3 = 6/2
we still have the initially 1/2 left so we will add that.
7/2
now we want to change it so that the denominator is equal to 4 so we multiply both top and bottom by 2
14/4
now we divide the 14 by 3 and you will get approximately 4. we will ignore the rest because it asks for whole servings and 3 only goes nicely into 14 4 times
Answer:
$=19400
Step-by-step explanation:
Average prices= $18,500
Number of prices that were quoted= 7
Expected sum that produces this mean= 7*18,500=$129,500
Sum of quoted prices=
$(15,500+ 18,800+ 16,900+ 19,900+18,000+21,000) =$110100
Next price to be quoted will be ;
$129,500-$110,100
$=19400
