Answer:
y=28
Step-by-step explanation:
6x-y=2
-y=2-6x
y=6x-2
4x-(6x-2)=-8
4x-6x+2=-8
-2x=-10
x=5
y=6*5-2=30-2=28
y=28
Answer:
Explained below.
Step-by-step explanation:
Complementary angles are angles that sum up to 90°.
Here,
Then,
Angle P + Angle Q = 90°
2x + 7x = 90°
9x = 90°
x = 90/9
x = 10°
Therefore,
- Measurement of Angle P = 2x = 2*10 = 20°
- Measurement of Angle Q = 7x = 7*10 = 70°

Speak in English please. I would be more pleased to help if you write in English.
Answer:
50 im sorry if im wrong
Step-by-step explanation:
<span>1C. 5^3 = 125 mL
2A. 30^3 = 27,000 mL = 27 L
3D. 75 mm is 7.5 cm, so we do: 7.5^3 = 421.875 mL = 0.421875 L =~ 0.422 L
Note:
1 mL = 1 cm^3
1 L = 1,000 mL
10 mm = 1 cm</span>
