Answer:
ereee
Step-by-step explanation:
The second one might be the answer
The 2x’s cancel out so you would combine the y’s and the other side of the equal sign to get 6y=30. You would then divide each side of the equal sign by 6 to get y alone, leaving you with y=5. Next, plug in the y to either the top or bottom equation. Plugging it in to the top, you would get 2x+4(5)=22. You would multiply 4 and 5 to then get 2x+20=22. Lastly, subtract 20 from both sides then divide by 2 to get x=1.
The answer is (1,5).
The sum of angles in a triangle is 180 degree
First angle + second angle + third angle = 180
From the given diagram , AC = BC
The angle opposite to the sides are also equal
So angle A and angle B are equal
Angle A = 50 so angle B = 50 degree
angle B = 2x = 50
Divide both sides by 2
So x= 25 degree
Angle A + angle B + angle C = 180
50 + 50 + 5y + 10 = 180
100 + y + 10 = 180
110 + 5y = 180
Subtract 110 on both sides
5y = 70
now divide both sides by 5
The value of y = 14
Answer:
248 in³
Step-by-step explanation:
L = 4, W = 6, H = 10
2(h × W) + 2(h × L) + 2(W × L)
= 2(10*6) + 2(10*4) + 2(6*4)
= 2(60) + 2(40) + 2(24)
= 120 + 80 + 48
= 248 in³
