The equations are,
3x + y = 8 ——— 1
4x - 2y = 3 ——— 2
Multiply equation 1 by 2
Which gives,
6x + 2y = 16 ——— 3
Now , add equation 2 and equation 3
Which gives,
10x = 19
From there , x = 19/10
Therefore x = 1.9
Now substitute x = 1.9 in the equation 1
So the equation becomes ,
3*1.9 + y = 8
From that ,
y = 8 - 5.7
Therefore , y = 2.3
So , x = 1.9 and y = 2.3.
Okay?
Answer:
w = 2/7
Step-by-step explanation:
You do 8 divided by 4 over 7, which is 2/7.
4.41*ten to the negative second power = 0.0441
Firstly, you have to calculate the 25 percent of the 32 apples which is 32 x 0.25 = 8. So the leftover apples would be 32 - 8 = 24. Since she divided the rest equally among 6 pies, you have to divide 24 by 6, which is 4.
Therefore there are 4 apples in each pie.
