Relationship is proportional ;
8 oranges
Step-by-step explanation:
Oranges (lb) 2 ___ 3 ____5 ___?
Price ($) __ 3 ___4.50___7.50_12
For proportionality :
Oranges = k * price
Where, k = constant of proportionality
2 = 3k
k = 2 /3
k = 0.666666
Using k :
Number of oranges at price = 4.50 should be:
0.66666 * 4.50 = 3
Number of oranges at price = 7.50 should be:
0.66666 * 7.50 = 5
Hence, relationship is proportional
Number of oranges at $12
0.66666 * 12 = 8
-6 + x = 4x pls help !
Answer:
Step-by-step explanation:
Alright so we are going to be simplifying here
-6 + x = 4x Flip sides
x-6=4x
After that,
x-6=4x Subtract 4x from both sides
-3x-6=0
Step 3
-3x-6=0 Add 6 to the sides
-3x=6
Step 4
-3x=6 Divide the sides by 3
-2
So therefore,
Your answer would be x=-2

holds 5 students and each bus hold 25 students, how many buses did they take?
Answer:
Number of cars = 14
Number of buses = 5
Step-by-step explanation:
Let
x = number of cars
y = number of buses
x + y = 19 (1)
5x + 25y = 195 (2)
From (1)
x = 19 - y
Substitute x = 19 - y into (2)
5x + 25y = 195
5(19 - y) + 25y = 195
95 - 5y + 25y = 195
- 5y + 25y = 195 - 95
20y = 100
y = 100/20
y = 5
Substitute y = 5 into (1)
x + y = 19
x + 5 = 19
x = 19 - 5
x = 14
Number of cars = 14
Number of buses = 5
Based on the number of vehicles and the number that each vehicle can take, the number of buses required is 4 buses.
There are 19 vehicles which take 5 students each. This means that the number of kids entering buses will be:
= 19 x 5
= 95 students
The students entering buses will be:
= Total number of students - Kids in vehicles
= 195 - 95
= 100 students
If each bus takes 25 students, the number of buses required is:
= 100 students / 25
= 4 buses
In conclusion, 4 buses were taken.

Solve this system of equations by substitution
x=y+3
x+7=2y
Answer:
(13, 10 )
Step-by-step explanation:
Given the 2 equations
x = y + 3 → (1)
x + 7 = 2y → (2)
Substitute x = y + 3 into (2)
y + 3 + 7 = 2y
y + 10 = 2y ( subtract y from both sides )
10 = y
Substitute y = 10 into (1) for corresponding value of x
x = 10 + 3 = 13
solution is (13, 10 )
Add these two expressions. (–45t + 53s) and (–3 – 75s + 2t) 65t + 415s – 3 –145t – 115s – 3 –115t + 113s – 3 115t – 415s + 2
Answer:
- 43t - 22s - 3
Step-by-step explanation:
(–45t + 53s) + (–3 – 75s + 2t)
Opening the brackets
-45t + 53s -3 - 75s + 2t
Collecting like terms
-45t + 2t + 53s - 75s -3
Simplify the expression
-43t -22s - 3
Line j passes through points (9, 6) and (6, 8). Line k passes through points (7, 9) and (5, 6). Are line j and line k parallel or perpendicular?
9514 1404 393
Answer:
perpendicular
Step-by-step explanation:
A graph shows the lines are not parallel. The lines are perpendicular.
__
j has a slope of -2/3 (down 2 for each 3 to the right)
k has a slope of 3/2 (up 3 for each 2 to the right)
These slope values have a product of 1, typical of perpendicular lines.

Answer:
32.85°
Step-by-step explanation:
Used a fancy calculator & just took a test like this
good luck, i hope this helps :)
Answer:
x = 32.8599
Step-by-step explanation:
you have the hypotenuse and the side adjacent to the angle, so you use
Cos(x) = adjacent/hypotenuse
so
Cos(x) = 21/25
x = cos^-1(21/25)
put this in a calculator:
x = 32.8599 (rounded)
Can someone help me?! The picture is below you don’t have to explain if you don’t want to!!
Answer:
(a) 3:4
(b) 3:4
(c) 9:16
Step-by-step explanation:
(a) The ratio of the sides would be 15:20 but after you simplify them (divide by 5), you'd get 3:4
(b) The ratio of the perimeter would be 60:80 because you're multiplying each side length by 4. When you simplify this again (divide by 20), however, it becomes 3:4 again
(c) To find the area, you would multiply the width times height, the ratio would be 225:400. You would get the greatest common factor which is 25 and divide it on both sides to get 9:16

Answer:
There are 100
Step-by-step explanation:
Answer:
Step-by-step explanation:
The numbers of containers in each row form an arithmetic progression, increasing by 3 each row.
common difference = 3
a₁ = 2
a₂₀ = a₁ + (20-1)d = 2 + 19×3 = 59
Total number = 20 × (a₁ + a₂₀)/2 = 20 × (2 + 59)/2 = 610

Dom runs a pizza business. Last year he took in $88 000 and it cost him $33 000
to run. What is his percentage profit for the year? Round to the nearest cent.
Answer:
The percentage profit for the year is 62.50%
Step-by-step explanation:
Here, we want to calculate the percentage profit
That would be difference between the revenue (88,000) and the cost (33,000) divided by the revenue * 100%
We have this as;
(88,000-33,000)/88,000 * 100%
= 55,000/88,000 * 100%
= 62.50%

Answer:
76 units
Step-by-step explanation:
In the given figure, a circle with center Q is inscribed in triangle AHD.
Let the circle with center Q touches the side HD at point N.
So, AT & AM, DM & DN and HT & HN are tangents drawn from external points A, D and H respectively.
Since, measure of tangsnts drawn from external point to a circle are equal.
Therefore,
AM = AT = 18
HN = HT = 8
DM = DN = 12
AH = AT + HT = 18 + 8 = 26
AD = AM + DM = 18 + 12 = 30
HD = DN + HN = 12 + 8 = 20
Perimeter of triangle
= AH + AD + HD
= 26 + 30 + 20
= 76 units
