1.
a. let k = constant
k = y/x
so k = 14/2 = 7
b. the equation would be y = 7x
2. a. k = y/x = 25/5 = 5
b. y = 5x
c. 50 = 5x, x = 50/5 = 10
L = 4w + 9.7
2l + 2w = 91.4
2(4w + 9.7) + 2w = 91.4
8w + 19.4 + 2w = 91.4
10w = 72
w = 72/10 = 7.2 cm
l = 4(7.2) + 9.7 = 38.5
Dimension = 38.5 by 7.2
Let x be the number of days for which the costs are the same, then
110 + 46x = 70 + 54x
54x - 46x = 110 - 70
8x = 40
x = 5
Therefore, it will take 5 days for the cost to be the same.
Answer:
2 in 52.3
Step-by-step explanation:
the two in 52.3 represents 2
I'm not 100% sure what the question wants as its answer, but having a class of 26 students is around the average number of students in a class.
