First= -2x+2y+3z=0
= -2x+2y+3z +-2y=0+(-2y)
-2x+3z=-2y
-2x+3z=-2y+-3z
-2x=-2y-3z
Divide both by negative two
-2x/-2=-2y-3z/-2
x=y+3/2z that’s the answer.

−(2x+5)=−10−2x
Step 1: Simplify both sides of the equation.
−(2x+5)=−10−2x
−2x+−5=−10+−2x(Distribute)
−2x−5=−2x−10
Step 2: Add 2x to both sides.
−2x−5+2x=−2x−10+2x
−5=−10
Step 3: Add 5 to both sides.
−5+5=−10+5
0=−5

I think the answer is c but i may be wrong, try using desmos online graphing calculator
Answer:
Step-by-step explanation:
1). ∵ 1 L = 1000 ml
∴ 4 L = 4000 ml
2). ∵ 1 cm = 10 mm
∴ 5 cm = 50 mm
3). ∵ 1 mg = 0.1 cg
∴ 5 mg = 0.5 cg
4). ∵ 1 ml = 0.001 L
∴ 25 ml = 0.025 L
5). ∵ 1 gm = 1000 mg
∴ 0.125 gm = 25 mg
6). ∵ 1 ml = 0.001 L
∴ 570 ml = 0.57 L
7). ∵ 1 mm = 0.1 cm
∴ 135 mm = 13.5 cm
8). ∵ 1 mg = 0.001 g
∴ 1820 mg = 1.82 g
9). ∵ 1 g = 100 cg
∴ 0.5 g = 50 cg
10). ∵ 1 ml = 0.001 L
∴ 0.2385 ml = 0.0002385 L
Answer:
Length is 90yards and width is 60yards
Step-by-step explanation:
Perimeter= 2( length+width)
let the width be x
then the length will be 30 + x
300 = 2(30+x+x)
150 = 30 + 2x
120= 2x
x = 120/2
x = 60 yards
length= 30+x
= 30 + 60
= 90yards
