Answer:
The value of x = 5 and y = 2
The correct answer is last option
Step-by-step explanation:
From the figure we can see that, subtraction of two matrices.
The resultant matrix shows the corresponding terms difference.
<u>To find the value of x</u>
1/2(x + 3) - (3*(-1)) = 7
x/2 + 3/2 +3 = 7
x/2 +3/2 = 7 - 3 = 4
x + 3 = 8
x = 8 - 3 = 5
x = 5
<u>To find the value of y</u>
8/2 -3 (y +1) = -5
4 - 3(y +1)/ = -5
3(y +1) = 4 + 5 = 9
y + 1 = 9 / 3 = 3
y = 3 - 1 = 2
Therefore the value of x = 5 and y = 2

Answer
they would need to sell 200 chocolate bars
Step-by-step explanation:
500 divided by 2.50 = 200
2 x 200 = 400
.50 x 200 = 100
400 + 100 = 500
Let the number be x.
7x-x=42
6x=42
x=7
the number is 7
