⓵ You need to solve the left side first in order to isolate the × and find it’s value :
-7× + 6 = 27
-6 -6
↓
-7× = 21
÷-7 ÷-7
↓
× = -3
If you find it too difficult to divide a number by a negative, just divide 21 by 7 and always remember that when dividing, when the signs are different the answer is negative. So knowing that you could just divide 21 by 7, which is 3, and add a negative sign in front!
I hope this helped, if there’s anything let me know! ☻
<u>Given</u>:
The number of tickets sold to children 
The number of tickets sold to adults 
The number of tickets sold to seniors 
To determine the percentage of tickets sold to seniors we need to determine the total number of tickets sold to each category.
<u>To determine the percentage of tickets sold to seniors:</u>
In order to determine the percentage of tickets sold to the seniors, we divide the tickets sold to seniors by the total number of tickets sold to children, adults, and seniors.
This value is multiplied with 100 to convert it into a percentage.
The number of tickets sold to seniors 
The total number of tickets sold to children, adults, and seniors 
The percentage of tickets sold to seniors 
Rounding this off, we get the value as 13.9%
Hence, option 1 is the correct answer.
Answer: 904.78 cu. ft
Step-by-step explanation:
Volume of sphere = 4/3 pi r^3
Assuming 12 ft. is the diameter of the sphere.
16/4 which could be simplified to be the whole number 4
The measures of the angles of a triangle add to 180.
45 + 45 + 90 = 180
The measures of these three angles do add to 180, ,so there is at least one triangle with these angle measures.
Using AA triangle similarity, any triangle with the same angle measures will be similar.
From the figure you already see two triangles with angles 45-45-90. There is an infinite number of triangles with those angle measures.
