Step-by-step explanation:
90*(2/5)=36
90-36=54
54*(2/3)=37
54-37=19
<u>Question </u>
Select the three equations that this diagram could represent.
<u> </u>
<u>Answer</u>
<em>Well, we first have to find out what the diagram says.</em>
<em>So what the diagram says is that 18 + 18 + 18 = 54.</em>
<em>Given this information, we have to figure what other answers = 54.</em>
<em>Therefore the answers are </em>
(A) 18 * 3 = 54.
(D) 54/18 = 3
(E) 54/3 =18
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.
