Answer:
hello :
90 = 15×6
75 = 15× 5
highest common factor of 90 and is 15 because highest common factor of 5 and 6 is 1
90 = 3² ×2×5
75= 5^3
common multiple of 90 and 75 is : 3²×2×5² = 450
90 and 75 both smaller than 100.
M(slope)= -5/4 point-slope(y-y1=m(x-x1)) so it would be y-5= -5/4(x+4)
Answer:
Option A
Step-by-step explanation:
Y is the amount of back pack
The total amount is represented by m
If Y is the cost of back pack purchased by Oliver, then 0.7 Y is the tax applicable on the purchase of back pack
Hence, the remaining cost would be total amount with Oliver minus the cost of back pack and the tax applicable on the purchase of back pack
Remaining cost = m - (y + 0.07y)
Hence, option A is correct
