(56/7)+(168/7)=8+24=32. Your answer is: 32
Answer:
i think its 4.8 x 10^7 meters
Step-by-step explanation:
hope this is right
x^2-4x=60
<h2>In a meeting room for a business event, there are 4 fewer chairs laid out in each row than the number of rows. The total number of chairs in the room is 60.</h2><h2 />
If each row has the same number of chairs as rows, then there is x^2 chairs.
Because there is 4 fewer chairs in every row, for every row you minus 4 - 4x
There a 60 chairs in total.
x^2 - 4x = 60
Substitute a number into the formula to check:
If there are 10 rows:
x = 10
10^2 - 4(10) = 60
100 - 40 = 60.
Answer:
0.7
Step-by-step explanation:
-2n +1.8 = 3.2
-2n = 3.2 - 1.8
-2n = 1.4
2n = - 1.4
n = 1.4 ÷ 2 = 0.7
1)y=3x
2)y=x
3)y=7x
4)y=x+7
4)y=2x+1
6)y=12x+2
