Answer:
Y = [-6 6 6 -6]
Step-by-step explanation:
From the given matrices
If X - 2Y = Z
b - 2c = a ... 1
a -2d = c ...2
4+2a = 16.... 3
a + 2b = b .... 4
From3 ;
2a = 16-4
2a = 12
a = 6
From 4;
a + 2b - b = 0
a+b = 0
a = -b
6 = -b
b = -6
From1;
b - 2c = a
-6 - 2c = 6
-2c = 12
c = -6
also
a - 2d = c
6-2d = -6
-2d = -6-6
-2d = -12
d = 6
Hence the matrices Y = [-6 6 6 -6]
Not sure but It should be -4/1
24 divided by 3 = 8
but thers two third so 8+8=16

Answer:
4/6 of a pizza.
Step-by-step explanation:
We know that:
Both pizzas are of the same size.
Jasmine cut her's into 12 slices.
Kelly cut her's into 6 slices, and ate 2 slices, then Kelly ate 2/6 of a pizza.
Jasmine ate X of a pizza, and we know that between them ate a total of 1 pizza.
This means that:
X of a pizza + 2/6 of a pizza = 1 pizza
X + 2/6 = 1
X = 1 - 2/6
X = 6/6 - 2/6 = 4/6
Jasmine ate 4/6 of a pizza, knowing that she cut her's into 12 slices, this would mean that she ate 8/12 of a pizza, or 8 slices.
Answer:
A
Step-by-step explanation:
This notation says that x+x+x+x+37=69
This can be simplified to say 4x+37=69
