Answer:
-21
Step-by-step explanation:
-6x + 2y = -18.........(i)
-3x - 2y = 54...........(ii)
add equ.(ii) to equ. (i)
(-6x + [-3x]) + (2y + [-2y]) = -18 + 54
-9x = 36
x = -4
sub x= -4 into equ (i)
-6(-4) +2y = -18
24 + 2y = -18
24 +18 = -2y
42 = -2y
y = -21
Step-by-step explanation:
Slope = 3 (Coefficient of x)
y-intercept = -2
Answer:
1
Step-by-step explanation:
When we substract 1 from any number then will get just previous number.
Example :
Let any number 17
17-1 =16
16 is the just previous number of 17
Therefore, A number -1 = previous number
Answer will be 1
90% in a fraction is the same as 90/100 simplified, is 9/10.
Hope this helps
The perimeter is (2 lengths) + (2 widths). Since the perimeter is 18 inches, (1 length) + (1 width) must add up to 9 inches.
If the length and the width must both be whole numbers, the only possible choices for the side lengths of this rectangle are:
1 x 8 in
2 x 7 in
3 x 6 in
4 x 5 in .
