A fruit company delivers
fruits
=> 3 large boxes and 2 small boxes weighs = 54 kilograms
=> 5 large boxes and 6 small boxes weighs = 108 kilograms
Now, let’s find how does each type of box weigh
=> 3a + 2b = 54, where a and b are the unknown weights of each boxes
=> 5a + 6b = 108
Multiply the first given equation by 3 on both side to cross out letter B
and find the value of A.
=> 3a(3) + 2b(3) = 54(3)
=> 9a + 6B = 162
Now subtract this by the second equation:
=> 9a + 6B = 162 – 5a + 6b =106
=> 4a = 56
=> 4a / a =56 /4
=> a = 14 – The weight of large boxes
Now, let’s find the B
=> 3(14) + 2b = 54
=> 42 + 2b = 54
=> 2b = 54 – 42
=> 2b = 12
=> 2b/2= 12/2
=> b = 6 = the weight of small boxes

Answer:
true
Step-by-step explanation:
im pretty sure its true
Step-by-step explanation:
Cosine Ratio is the best tool to solve this problem.
cos38°=x/8
x =8*cos38°
x = 8*0.79
x = 6.32
Answer:
18/44
Step-by-step explanation:
To turn 9/22 into something over 44, we need to figure out what to multiply it by.
44 / 22 = 2.
Multiply 9/22 by 2:
9/22 * 2 = 18/44
