This shows that there are 141 men and 21 women in the meeting
Let the number of men present be x
Let the number of women present be y
If the total number of students present in the meeting is 162, hence;
x + y = 162 ............ 1
If there were 15 men more than 6 times the women, then;
x = 6y + 15 ...................2
Substitute equation 2 into 1:
6y + 15 + y = 162
7y + 15 = 162
7y = 162 - 15
7y = 147
y = 21
Recall that x = 6y + 15
x = 6(21) + 15
x = 126 + 15
x = 141
This shows that there are 141 men and 21 women in the meeting

Ben said: For every $60 the sixth graders plan to raise, the seventh graders
plan to raise $90. He looks at the principal's thermometers and sees that
$60 is at the same place on the sixth-grade thermometer as $90 is on
the seventh-grade thermometer.
Ben also makes the claim: For every $30 the sixth graders plan to raise,
the seventh graders plan to raise $45.
Do you agree with this claim? Explain your reasoning.
Answer:
yes
Step-by-step explanation:
for every 60 is 90 right so if you take 30 ( half of 60) how much are the 7th graders gonna raise half of 90 is 45 (may I please have brainliest I need it to rank up)

at a distance of 5 units from their point of point of intersection. Find the coordinates of the foot of perpendiculars drawn from p1 , p2 on the bisector of the Angle between the given lines.
Answer:
(0, 5√3/2 + 2)Step-by-step explanation:
Given is the absolute value function.
Observations:
It has a slope of ±√3 and the y- intercept of 2.There is no horizontal shift, so the the y-axis is the line of symmetry.The y-axis is also an angle bisector of the two lines.The foot P₁P₂ is parallel to the x-axis since it's perpendicular to the y- axis.We need to find the coordinates of intersection of the line P₁P₂ with the y- axis (the point Y in the picture).
Consider the triangle AYP₂.
We know AP₂ = 5.
The angle YAP₂ is:
arctan (1/√3) = 30°The distance AY is:
AY = AP₂ cos 30° = 5*√3/2The distance from the x-axis to the point Y is:
5√3/2 + 2, added the y- intercept of the graphed linesThe coordinates of the point Y:

Brad's science class is heading to Skylight Observatory on a field trip. The observatory offers
a group rate for students that is $4 less per person than the normal cost. There are 27
students in Brad's science class. His teacher called ahead and found that the total cost for the
class will be $378. What is the normal cost per person?
Answer:
$18
Step-by-step explanation:
378 ÷ 27 = 14
14 + 4 = 18
The normal cost per person = $18
The normal cost per person is $18.
Given,
Brad's science class is heading to Skylight Observatory on a field trip.
The observatory offers a group rate for students that is $4 less per person than the normal cost.
There are 27 students in Brad's science class.
The total cost for the class is $378.
We need to find the normal cost per person.
How do we equally find the cost of each item from the total cost?We divide the total cost by the number of items.
Example:
7 bags cost $49
1 bag cost = $49 / 7 = $7
We have,
The number of students = 27
The total cost of the class trip with the offer = $378
Offer = $4 less than the normal cost per student
Now,
The offer cost for each person:
= $378 / 27
= $14
The normal cost for each person:
= $14 + $4
= $18
Thus the normal cost per person is $18.

how would I solve this??
Answer:
y = 140
Step-by-step explanation:
you'd do:
y=25(7)-35
y=175-35
y=140
to double-check your math:
140 = 25(7)-35
both sides will equal 140 (or the same value) if done properly

70 = 19 - 3x
what does x equal?
Step-by-step explanation:
→ 70 = 19 - 3x
→ - 19 + 70 = -3x
→ 51 = -3x
→ -3x = -51
→ x = -51/3 = -17
→ x = -17
therefore, value of x is -17.

PLEASE HELP , WILL GIVE A BRAINLY. What is the domain of the function?
Answer: I believe it is a. Sorry if I am incorrect
Step-by-step explanation:
Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
Determine if I Il m based on the information given on the diagram. If yes, state the converse that
proves the lines are parallel.
Answer:
I believe, that they are parallel because they both have 90° angles meaning that the other angle has to be 90° as well. I dont really know how to explain it but they are both in the same position and have 90° angles im not the best with these. •So im not exactly sure if this is correct though.
-They also have corresponding and congruent angles that do match up, so yes they are parallel to eachother

Find x and y please!! I’m desperate!!!
Answer:
x = 4
y = 2
Step-by-step explanation:
the third angle of the triangle
180 - (148 + 18) = 14º
Therefor
3x + y = 14
5x - y = 18
Add the equations
8x = 32
Divide both sides by 8
x = 4
Plug in x = 4
3(4) + y = 14
12 + y = 14
y = 2
9514 1404 393
Answer:
(x, y) = (4, 2)
Step-by-step explanation:
The triangles are similar by AA similarity, so the corresponding angles are congruent.
5x -y = 18 . . . . . . unmarked angles are congruent
18 +(3x+y) +148 = 180 . . . . . sum of angles in a triangle is 180°
__
After subtracting 166 from both sides, the second equation simplifies to ...
3x +y = 14
Adding this to the first equation gives ...
8x = 32
x = 4 . . . . . . divide by 8
Then substituting for x in the first equation gives ...
5(4) -y = 18
20 -18 = y = 2
The values of the variables are x = 4, y = 2.

The width of a rectangle measures (26 – 8c) centimeters, and its length measures
(106 + 6c) centimeters. Which expression represents the perimeter, in centimeters,
of the rectangle?
Answer:
first one is correct
Step-by-step explanation:
length of a rectangle = 2b - 8c
breadth of a rectangle = 10b + 6c
now , formula to calculate the perimeter of rectangle is
p = 2 (l + w)
no substitute the value of l(length) and w(width)
p = 2{(2b - 8c) + (10b + 6c)}
p = 2(2b - 8c + 10b + 6c)
p = 2(12b - 2c)
p = 24b - 4c

Find the inverse function in slope-intercept form (mx+b):
f(x)=2x-8
Answer:
[tex]\sf f^{-1}(x) = \dfrac{x}{2}+4[/tex]
Step-by-step explanation:
A function is given to us and we need to find the inverse of the function in slope intercept form . The given function is ,
[tex]\sf\implies f(x) = 2x - 8 [/tex]
Let us assume that y = f(x) , so that ,
[tex]\sf\implies y = 2x - 8 [/tex]
Now interchange the positions of x and y , we have ,
[tex]\sf \implies x = 2y - 8[/tex]
Solve for y in terms of x ,
[tex]\sf \implies 2y = x + 8 \\\\\sf\implies y =\dfrac{x}{2}+4 [/tex]
This is the inverse of the function in slope intercept form. Now we can replace this y with f-¹(x) , as ,
[tex]\sf \implies \boxed{\pink{\frak{f^{-1}(x) = \dfrac{x}{2}+4}}}[/tex]
