Answer:
Step-by-step explanation:
275/3=91.6 recurring
91.6 recurring x 15= 1375
Step 1
Let n represent car and m represent motorcycles.
n + m = 50 ...................1
car has four wheels and motorcycle has two wheels
4n + 2m = 164 .............................. 2
Step 2
Solve equation 1 and 2 simultaneously.
from (1), make n subject of relation and substitute in equation 2.
n = 50 - m
Step 3
Substitute n in equation 2
4(50 - m) + 2m = 164
200 - 4m + 2m = 164
collect like terms
200 - 164 = 4m - 2m
36 = 2m
m = 36/2
m = 18
next find n
n = 50 - m
n = 50 - 18
n = 32
There are 32 cars and 18 motorcycles.
Question 1: c. ) 8^4 question 2: 4^7 question 3: 7^6 question 4: 4^3 question 5: 3^2
A. y=5+1.5d
b. after 20 days it will be 5+ 1.5 × 20 = 5+ 30= 35 cm
