a hexagon is also 180 degrees
Answer:
B. 8
Step-by-step explanation:
Calculate how many 2 point answers and 5 point answers there are.
2 x 8 = 16
Since there are half as many 5 point answers as there are 2 point answers,
5 x 4 = 20
calculate how many remaining questions there are. The numbers would be 8 since you had 8 2 point questions and 4 since half of 8 is four.
8 + 4 = 12
Subtract that number by the total questions, which is 28.
28 - 12 = 16
Next figure out how many 4 point questions you had (28-12=16)
16 x 4 = 64
To check your work add up the totals and see if they match up to 100.
16 + 20 + 64 = 100
Step-by-step explanation:
Answer:
The sum of 4 times a number and -3 added to 9 times the number is:
4x + (-3 + 9x)
Step-by-step explanation:
Determine what each of the words means
"the sum of" - you are going to be adding the following two numbers.
"4 times a number" - Let x be the number, so, 4x is the first number.
"and -3 added to" - again, it's going to be addition of this number and the following number.
"9 times the number" - let x be the number, so, 9x is the second number in the second addition.
Now that we know what it all means, put it together:
4x + (-3 + 9x)
I really hope this helps you =)
