Answer:
B). (-4, 5)
Step-by-step explanation:
-2x – 3y = -7 | ×2 |
-4x + y = 21 | ×1 |
-4x – 6y = -14
-4x + y = 21
____________ --
-7y = -35
y = -35/-7
y = 5
-4x + y = 21
-4x + 5 = 21
-4x = 21 - 5
-4x = 16
x = 16/-4
x = -4
Answer:
m
Step-by-step explanation:
Given parameters:
Length of rope = 11m
First length cut off =
m
Second length cut off =
m
Unknown:
Remaining length = ?

Let us find the total length cut off first;
=
m +
m
= 
=
m
So,
Remaining length = 11 - 
=
=
m
# of blankets at the beginning = b
11 = b - 9
11 + 9 = b
b = 20
