Answer:here we go
Step-by-step explanation:
13x+(4x+10)=180
Simply brackets
13x+4x+10=180
17x+10=180
-10
17x=180-10
17x=170
170/17=10
X=10
2(y+25)+2y−30=180
2y+50+2y−30=180
add like terms
4y+20=180
4y=160
160/4=40
Y=40
13x=130
(4x+10)=50
2(y+25)=130
(2y-30)=50
Answer:
Step-by-step explanation:
2*x + 3 = 1/2x + 30 Subtract 3 from both sides
<u> - 3 -3</u>
2x = 1/2x + 27 Subtract 1/2 x from both sides
<u>1/2 x -1/2 x</u>
1 1/2 x = 27 change 1 1/2 to 3/2
3/2 x = 27 Multiply by 2/3
2/3 * 3/2x = 27 * 2/3
x = 18
Number of sides is 6- Hexagon
Sum of interior angles equation- s=(n-2)*180
s= (6-2)*180
s= 4*180
s=720
Sum is 720

So basically a decimal is moved based on how many zeros are in the dividing number
Ex. 51,000/100
because there are 2 zeros in the number one hundred, the decimal in 51,000 gets moved 2 places to the left
So it goes from 51,000 to 510
Ex. 16 * 1000
There are three zeros in the number 1000. This means three zeros will be added onto the number 16
So the answer would be 16,000
