[(21 + 6) − 3^2] ÷ 9 ⋅ 2=[(27) − 9] ÷ 9 ⋅ 2
=18 ÷ 9 ⋅ 2
= 2 . 2
= 4
[True]
Natural numbers are the positive integers (whole numbers) such as 1, 2, 3, and etc. So it is true that zero is less than every natural number.
[Hundreds]
The 8 in 30,846 is in the hundreds place because the 8 stands for 800.
Answer:
that no. is 20
Step-by-step explanation:
let us take that certain no. as x
so
2/5. x +2=10
2x/5 = 10-2
2x = 8×5
x= 40/2
x= 20
Answer:
1) A
2) A
3) B
4) D
5)A
6) D
7) A
8) C
9) D
Step-by-step explanation:
1) -5 (-2) -6= 4
2) 3 coins plus c coins = 3 + c
3) x-2 =16, x = 18
4) 
=-5. Clearing, z = 60
5) x =13,4
6) 14=t-4. Clearing t = 58
7) -30=j+50, clearing j=80
8) 2.8x=-9.24, clearing x=-3-3
9) 5.8= 
. Clearing z=12.76
The answer is 8.06. Follow these steps. This is an example.
a2+b2=c2
9^2+12^2=c^2
81+144=c^2
225 =c^2
Since 225 = c2, take the square root of both sides to solve for c.
225=c^2
So the answer is
±15
