ASAP plz
Answer: 16
Step-by-step explanation:
Tim can buy 4 caps and will left with Rs.20 to spare
What is the unitary method?The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
Given here tim can buy 3 hats from Rs.120 thus each hat cost Rs.40
Thus price of 4 hats is Rs.160 and he will be left with Rs.20 to spare.
Hence, Tim can buy 4 caps and will left with Rs.20 to spare

7 + 5x = 2x + 25
step by step pls:(
Answer:
x = 6
Step-by-step explanation:
7 + 5x = 2x + 25
first subtract 7 from both sides to isolate 5x on the left
5x = 2x + 18
then subtract 2x from both sides to isolate all of the x terms to one side
3x = 18
then divide 18 by 3 to solve for x
x = 6

A college information pamphlet provides some statistics about the students and the professors to help high school seniors decide if they want to attend the college. The pamphlet lists the ratio of students to professors as 18 to 1. If there are 702 students at the college, how many professors are there?
Answer:
39
Step-by-step explanation:
Setting up your problem and solving:
In the question it says the ratio is students to professors right? So 18 to 1.
Write that down: Students to Professors is 18 to 1.
We know that there are 702 students in that college correct?
Write that down: 702 students in the college
We are trying to find how many professors there are so...let's do that.
Number 1:
Set your equation: have your fraction bar and equal sign like this: --- = ---
On the top, we have 1 so... 1/? = ?/?
On the other top we have the x...: 1/? = x/?
Why? Because we do not know the total of professors there are so that is X.
We put the number 1 on the other side because we know that there is only 1 out of 18 professors to students.
Number 2:
On the bottom, we will have 18...: 1/18 = x/?
On the other bottom we have 702...: 1/18 = x/702
Why? Because we know that there is a total number of 18 to 1 students on the ratio and a real total of 702 students.
Number 3.
Now you have your equation set up: 1/18 = x/702
The next step is yours: cross multiple, divide on the bottom or top or find the comparison.
I'm going to divide by the bottom okay? so.. 18/702
Set that up.
(702/18)
702/18 is 39!
SO in the end there is a total of 39 professors!
'x=39'
Hoped this helped! :)

a line has a slope of 8 and a y intercept of 9 what is its equation in slope intercept form
Answer:
y= 8x +9
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is 8, m= 8.
Substitute m= 8 into the equation:
y= 8x +c
Given that the y-intercept is 9, c= 9.
Substitute c= 9 into the equation:
y= 8x +9
Thus, the equation of the line is y= 8x +9.

Answer:
"I Only" is the correct answer
Step-by-step explanation:
Given inequality is:
-10>3x-6
In order to check which numbers are solution to the given inequality, we will put each number one by one in the inequality. If the inequality is true after putting the number, the number is the solution of the inequality.
So,
I . -10
Putting -10 in the inequality
[tex]-10>3x-6\\-10>3(-10)-6\\-10>-30-6\\-10> -36[/tex]
The inequality results in true after putting x=-10 so -10 is the solution of inequality.
II. 5
Putting 5 in the inequality
[tex]-10>3x-6\\-10>3(5)-6\\-10>15-6\\-10>9[/tex]
The equality doesn't hold true for x=5 so 5 is not the solution of the problem.
III. -1
Putting -1 in the equation
[tex]-10>3x-6\\-10>3(-1)-6\\-10>-3-6\\-10>-9[/tex]
Inequality doesn't hold true for x=-1 so it is not the solution of the inequality.
Hence,
"I Only" is the correct answer as only -10 is the solution of inequality.

f(-7) = -4
Answer:
f(-7)=-4
Step-by-step explanation:
If you look at the x, in this case -7, and follow it down to where it stops on the parabola, you will see that it's y value is -4.

77th term for -10,-8,-6
9514 1404 393
Answer:
142
Step-by-step explanation:
The first term of this arithmetic sequence is -10. The common difference is -8-(-10) = 2. The n-th term is ...
an = a1 +d(n -1)
an = -10 +2(n -1) = 2n -12
Then the 77th term is ...
a77 = 2(77) -12 = 154 -12
a77 = 142
The 77th term is 142.
Find the inequality represented by the graph
Answer:
y ≥ 1/2xStep-by-step explanation:
Given the following inequality, we know that y must be greater than or equal to x because the line is not dashed, and is shaded above the line.
Now to find the equation just pretend that this is just a normal linear equation, and solve for the equation.
So since the y intercept is 0, and there is a rise of 1 for a run of 2 or 1 unit up every two units to the right, the corresponding linear equation is y = 1/2x.
Now since this is an inequality where y is greater than or equal to x.
y = 1/2x → y ≥ 1/2x
