Answer:
a.114.4kg
b. 486kg
Step-by-step explanation:
Firstly , we want to know the value with which the apples weigh more than the oranges
To calculate this, we simply subtract the weight of the oranges from that of the apple
Mathematically, that would be ;
300.2-185.8 = 114.4kg
The total weight of the things bought is calculated by adding both weights together
That would be 185.8 + 300.2 = 486 kg
Answer:
See the below part
Step-by-step explanation:
1)
8 - 2x = 5 - 4x
=> 8 - 5 = -4x + 2x
=> 3 = -2x
=> 3/-2 = x
=> -3/2 = x
2)
4 + 3x = 2 - 2x
=> 4 - 2 = -2x - 3x
=> -2 = -5x
=> 2 = 5x
=> 2/5 = x
3)
2(x - 1) + 2(3x - 1) = 0
=> 2x - 2 + 6x - 2 = 0
=> 8x - 4 = 0
=> 8x = 4
=> x = 4/8
=> x = 1/2
3(n-9)=-3
3n-27=-3
3n=-30
n=-10
They are not congruent, they have different measurements
