Setting 7 / 3 equal to which ratio would result in a valid proportion? a.9 / 49 b.18 / 42 c.42 / 18 d.49 / 9
solve the proportion. where necessary, round to the nearest hundredth. 8/2 = x+3/4
Answer:
x = 13
Step-by-step explanation:
8/2 = (x + 3)/4
~Simplify
4 = (x + 3)/4
~Multiply 4 to both sides
16 = x + 3
~Subtract 3 to both sides
13 = x

Use the table to answer the questions.
X Y Point
-8 8 L
0 4 M
4 2 N
8 0 P
Calculate the slope between point L and point M using the change in y and the change in x. Show all work in the formula. slope =m =
2) Calculate the slope between point N and point P using the change in y and the change in x. Show all work in the formula. slope =m =
3) Write the letter and ordered pair of the y-intercept.
Answer:
See below for answers
Step-by-step explanation:
1) Slope is Rise/Run=(y2-y1)/(x2-x1)=(4-8)/(0-(-8))=(-4/8)=-1/2, therefore m=-1/2
2) Slope is Rise/Run=(y2-y1)/(x2-x1)=(0-2)/(8-4)=-2/4=-1/2, therefore m=-1/2
3) The y-intercept is point M because the y-intercept of a function is where the graph will cross the y-axis which also means the y-value when x=0. Therefore, the y-intercept is point M which is (0,4)
1. M=-1/2
2. M=-1/2
3. The y-intercept is point M which is (0,4)
BRAINLIEST PLZ HELP!!!! Which inequality is represented by this graph?
Answer:
I think its the last one????
Step-by-step explanation:
Answer:
D.
Step-by-step explanation:
If the circle is filled in that means that it is equal to (the line under the inequality). And the inequality sign is facing the same direction as the graph (which in this case is right) so that means that the inequality sign in facing right!

an arts academy requires there to be 3 teachers for every 51 students and 5 tutors for every 45 students. how many students does the academy have per teacher? per tutor? how many tutors does the academy need if it has 90 students? The academy has ___ students per tutor
Answer:
17 students per teacher, 9 students per tutor. You need 10 tutors if the school had 90 students.
Step-by-step explanation:
51 students divided by 3 teachers = 17 students per teacher.
45 students divided by 5 tutors = 9 students per teacher.
If there are 9 students per tutor 9 * 10 = 90 so ten tutors

Which is the best estimate for 6,193 ÷ 48 using compatible numbers.
A. 100
B. 120
C. 150
D. 160
The best estimate for 6,193 ÷ 48 using compatible numbers is 120. Therefore, option B is the correct answer.
Given that, 6,193 ÷ 48.
What is the division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
Here, the number 6,193 can be rounded off to 6000 and the number 48 can be rounded off to 50.
So, 6,193 ÷ 48
= 6000 ÷ 50
= 120
The best estimate for 6,193 ÷ 48 using compatible numbers is 120. Therefore, option B is the correct answer.
