Find the value of x and y
Step-by-step explanation:
5x-17 and 3x-11 are supplementary angles
They add up to 180 degrees
5x-17 + 3x - 11 = 180
8x - 28 = 180
8x= 208
x= 26
3x-11, 90, and 2y + 5 added together equal 180
3x-11 + 90 + 2y + 5 = 180
3(26) - 11 + 2y + 5 = 90
78 - 6 + 2y = 90
72 + 2y = 90
2y = 18
y = 9
I hope this helps!!!

Answer:
(x, y) = (0, -3)
Step-by-step explanation:
Using the second equation, we can substitute for x in the first equation:
6(y+3) -5y = 15
y +18 = 15 . . . . . collect terms
y = -3 . . . . . . . . . subtract 18
Using the second equation:
x = y +3 = (-3) +3 = 0
The solution is ...
x = 0
y = -3

Step-by-step explanation:
What fraction of 60 is 90?
The fraction would be the part of the number over the actual number.
The fraction would be 60/90
Dividing both numbers by 30, the fraction reduces to 2/3
The answer is 2/3
Answer:
Solution given:
let fraction be x.
equation becomes:
60/x=90
doing crisscrossed multiplication
60=90x
dividing both side by 90
60/90=90x/90
x=60/90
reduced the term
x=⅔
⅔ is fraction of 60 to get 90
A retail outlet offers a retention bonus for each shopping season an employee remains with the company. Samuel's starting pay is $12.50/hr. For each season Samuel remains with the company, he receives a $0.35/hr raise. Find f(n), Samuel's hourly rate after n seasons with the company. Then determine his hourly rate after 18 seasons. f(n)= After 18 seasons with the company, what will Samuel's hourly rate will be $ /hr. (Round to the nearest cent.)
Answer:
Samuel's hourly rate after n seasons with the company is f(n)= 12.50 + 0.35*n. After 18 seasons with the company, Samuel's hourly rate will be 18.8 $ /hr.
Step-by-step explanation:
You know that Samuel's starting pay is $12.50/hr and for each season Samuel remains with the company, he receives a $0.35/hr raise.
Samuel's hourly rate after n seasons at the company will then be:
f(n)= 12.50 + 0.35*n
To determine the hourly rate after 18 seasons, you must replace the value n with 18:
f(18)= 12.50 + 0.35*18
Solving you get:
f(18)= 12.50 + 6.3
f(18)= 18.8
Samuel's hourly rate after n seasons with the company is f(n)= 12.50 + 0.35*n. After 18 seasons with the company, Samuel's hourly rate will be 18.8 $ /hr.

For a filed trip the school bought 47 sandwiches for $40.60 each and 39 bags of chips for $1.25 each. How much did the school spend in all?
Answer:
$1,956.95
Step-by-step explanation:
The school bought 47 sandwiches for $40.60
= 47 × 40.60
= 1,908.2
They also bought 39 bags of chips for $1.25
= 1.25×39
= 48.75
Therefore the total amount spent can be calculated as follows
= 48.75 + 1,908.2
= 1,956.95
Hence the total amount spent by the school is $1,956.95
SOMEONE HELP ASAP PLS :(
question 3 please :) (exact values)
Answer:
(a) h = 160 - 5·x
(b) V = 4·x² × h = 4·x² × (160 - 5·x) = 640·x² - 20·x³ = 20·x²·(32 - x)
∴ V = 20·x²·(32 - x)
Step-by-step explanation:
(a) The given dimensions of the cuboid (rectangular prism) are;
'4·x' meters by 'x' meters by 'h' meters
Let the 4·x meters represent the length, 'l', of the cuboid, let the x meters represent the width, 'w', of the cuboid, and let the h meters represent the height 'h' of the cuboid
Therefore, we are given that the cuboid is a wire cage, with the total length of the sides (edges) of the cuboid equal to 640 meters
Therefore, the sum of the edges are;
Top(4·x + x + 4·x + x) + Side(h + h + h + h) + Bottom(4·x + x + 4·x + x) = 640
20·x + 4·h = 640
∴ h = (640 - 20·x)/4 = 160 - 5·x
h = 160 - 5·x
(b) The volume of a cuboid, V, is given as follows;
V = The area of the base of the cuboid × The height of the cuboid
The area of the base of the cuboid = l × w = 4·x × x = 4·x²
The height of the cuboid = h = 160 - 5·x
∴ V = 4·x² × (160 - 5·x) = 640·x² - 20·x³
V = 640·x² - 20·x³ = 20·x²·(32 - x)
∴ V = 20·x²·(32 - x) QED.

At the bottom of the screen it says "the equation that models the situation is..."
y-y1 = m(x-x1) — point-intercept form
Given both x1 and y1 = coordinate point.
First we have to find the slope by using rise over run. (y2-y1)/(x2-x1) = m
The slope should be m = -4 then we substitute m-value in point-slope form.
y-y1=-4(x-x1) — new equation. After substituting slope in, we need to find the coordinate point that is part of the graph. You can use any points that are given in the picture. I will use point F or (5,0).
Then we substitute x1 = 5 and y1 = 0 in the point-slope form
y-0=-4(x-5) — point-slope form
y=-4x+20 — slope-intercept form..
How about we change to another coordinate point to substitute in? We can check if these points also give same equation (slope-intercept).
Let's substitute (4,4) in the equation.
y-4=-4(x-4)
y=-4x+16+4
y=-4x+20
Same answer. Meaning that all these points that are shown can be substituted in the equation and get the same slope intercept form.
Therefore, point-slope form for the graph can be
y-4=-4(x-4)
you can also change the coordinate point value.

10) 9 people can paint a bridge in 5 hours,
How long would it take 2 people to paint the bridge?
Question 1.
Step-by-step explanation:
The number of people to paint the bridge is inversely proportional to the number of hours it takes.
(If there are more people, it will take less time etc.)
9 people can paint the bridge in 5 hours.
=> 2 people can paint the bridge in 5 * (9/2) = 22.5 hours.
HELP PLEASEEEEE!!!!!!!!!
Please help due ASAP
Show workings please
Step-by-step explanation:
I don't know if this is the right way to so it, but I would do it like this
since a triangle has 180 degrees, the angles all have to add up to 180
So 180 = a + b + c
we already know a, its 95
So 180 = 95 + b + c
now we know the equation for b, so we'll just put it there instead of the b, and since the angles are the same, we should put it instead of c too
180 = 95 + (4x-15) + (4x-15)
now subtract 95 from both sides
85 = (4x-15) + (4x-15)
add the xs and numbers together
85 = 8x - 30
now add the 30 to both sides
115 = 8x
divide by 8
your x is 14 3/8 or 14.375 or 115/8
that's not your angle, that's your x

what should be done first to simplify 18 – 3 + 5 + 2 – 13 + 12 ??
answer:
18 - 3 should be done first.
step-by-step explanation:
this should be done because of PEMDAS. the rule states that between addition and subtraction, you have to go from left to right. therefore, 18-3 comes first when going from left to right.
