Step-by-step explanation:
5x+3x-14=180
8x-14=180
8x=180+14
8x=174
x=174/8
x= 21.75°
if x is 21.75°, then 5x is 108.75°
which means 3x-14 is 51.25°
therefore, f +108.75+51.25=180
f = 180-160
f=20°
Probability of spinnin a 2 = 1/8
Probability of rollin a 3 = 1/6
<span>probability of spinning a 2 and rolling a 3 = 1/8 * 1/6 = 1/48
Answer is B

Answer:
We need to know how many students are in sixth grade and compare the real number with the 84 sixth graders that Jasmine claims to be.
Step-by-step explanation:
We would need to know how many students are in sixth grade to determine who is right. If two students out of seven have an overdue library book and grace claims that 24 of them are overdue by that means, what we would need to do is divide the allegedly 24 students between 2. Now we have 12 pairs of students that have overdue books. For every pair of students in sixth grade that have overdue books, seven students don’t have overdue books, so now we multiply 12 pairs of students with overdue books times 7 students who don’t have overdue books. By Jasmine calculation then, sixth grade have 84 students.
If sixth grade have indeed 84 students, Jasmine is right. If there are not 84 students in sixth grade, she is wrong. Grace is right if there are fewer students than 84 in sixth grade.
Use PEMDAS.
P = Parentheses
E = Exponent
M = Multiplication
D = Division
A = Addition
S = Subtraction
This is the order of operations.
For example, let's take the second equation.
36 / 6 + 10 * 66
There are no parentheses or exponents.
So, first we multiply.
36 / 6 + 660
Then we divide.
6 + 660
Then we add.
666
So the equation equals 666.
