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]
Answer:
B 10.211 < 10.210
Step-by-step explanation:
Evaluating each of the given statements one by one:
A 10.345 > 10.340
Decimal values at the tenth and hundredth place are the same on both sides while the thousandth part value is greater on the left side.
Hence, this statement is true
B 10.211 < 10.210
Decimal values at the tenth and hundredth place are the same on both sides while the thousandth part value is greater on the left side.
Hence , this statement is not true because 10.211>10.210
C 9.999 < 10.0
This statement is true because 9.999 is less than 10.
D 6.3 = 6.30
This statement is correct as the left hand side is the same as right hand side.
Answer:
im sorry idk this answer but lemme get your snap
I'm not sure exactly what it is but it would be a negitive
I like using decimals instead of fractions.
1/8: 0.125
So the scale is:
0.125 in: 1.5 mi
What you do to one side you have to do to the other side. We have the map distance, which is 2.5. Let's see what it was multiplied by to find the map distance of their houses.
2.5÷ 0.125= 20
Let's multiply the other side by 20.
20×1.5
30
So, Juanita and Lindsey live 30 minutes away.
