Nike and Adidas are having a huge sale for the next 5 days. Create a graph to determine if the shirts and cost are proportional.
A) Is the number oft-shirts proportional to the cost?
B) Write an equation to illustrate the relationship between the number of t-shirts and cost?
C) Using the equations predict the cost of 20 shirts sold.
D) 1%at docs the point (5, 35) represent in the context ofthc situation pertaining to Nike?
E) Which company has the better cost per shirt?
Answers
Answer:
See the graph with both lines attached
A) From the tables we see the constant change of values in the second column and the initial value is zero.
This represents a proportional relationship.B) Rate of change is 7 per shirt, the equation is:
y = 7x, where y is cost, x - is the number of shirtsC) When x = 20,
y = 7*20 = 140Cost of 20 shirts is $140D) The point (5, 35) represents that:
The cost of 5 shirts is $35E) The second table has confusing titles (not about the number or cost of shirts) but if we assume its same as the first table, then Adidas has greater price of $8 per shirt.
Comparing the prices, Nike has better cost
price of $8 per shirt.
Comparing the prices, Nike has better cost

Nella travelled 1/3 of a journey by bus, 2/3 of the remainder by bicycle and the remaining 9 km on foot. a)How far did Nella cycle? b)What was the total distance that Nella travelled?
Answers
Answer:
18km
40.5km
Step-by-step explanation:
Let b = journey by bus
c = journey by bicycle
d = total journey
c = (2/3 x d) x 2/3
divide both sides by 2/s
c(3/2) = (2/3)d
c + 9km = 2/3d
c + 9km = 3/2 c
collect like terms and solve for c
3/2c - c = 9km
1/2c = 9km
c = 18km
2. IF cycling (18km) and walking (9km) make up 2/3 of the journey, 2/3 of the journey is 27km
2/3d = 27km
divide both sides by 3/2 to find d
d = 40.50 km

10. Solve for all values of x algebraically (find the zeroes):
3x^2 +12x – 7 = x^2+ 3x – 2
Answers
Answer:
x = -5 or 1/2
Step-by-step explanation:
From the question,
3x²+12x-7 = x²+3x-2
Collect like terms
3x²-x²+12x-3x-7+2 = 0
2x²+9x-5 = 0
Using factorization method to solve the quadratic equation
2x²+10x-x-5 = 0
(2x²+10x)-(x+5) = 0
2x(x+5)-1(x+5) = 0
(x+5)(2x-1) = 0
Either,
x+5 = 0
x = -5
or,
2x-1 = 0
2x = 1
x = 1/2.
Therefore,
x = -5 or 1/2

Answers
Answer:
Step-by-step explanation:
18/14 and 10/15 don't have the same value. Only equivalent fractions have same value.
These two are not equivalent fractions
Answer:
No.
Step-by-step explanation:
Without much calculation, we can notice that 18/14 is actually greater than 10/15 since its numerator is greater than its denominator, making it greater than 1. However, 10/15 is less than 18/14 since its numerator is less than its denominator making it less than 1. In short:
18/14 > 1
10/15 < 1
18/14 > 10/15
