Answer:
7=-10s-3, would mean that s= -1
Step-by-step explanation:
9.2 m
Because 1 cm = 0.01 m
So 920 x 0.01 = 9.2
The commutative property is when you change the order but not the answer. To better understand what they are asking you, let's let x=1- 6 * 2 * 1=12; Answer A wouldn't be right because there are no 6,2, or x's. Remember you just change the ORDER not the GROUPING so Answer B is wrong too. Now Answer C and Answer D are left. Now you just need to look at the signs. 6(2) just means 6 TIMES 2 so pick the option with multiplication. So your answer is C. Hope I helped!
Write this story as equations:
s = 5j
(s+12) = 2*(j+12)
Then solve:
5j+12 = 2j + 24 => 3j = 12 => j=4, s=5*4=20

In 12 years they will be 32 and 16
Answer:
Number of points, x, Number of segments, y
x: 2, 3, 4, 5, ... N,. ...
y: 1, 3, 6, 10, ... (N-1)(N)/2, ...
Step-by-step explanation:
Adding Nth point, there are N-1 new segments,
and (sum over {i = 1 to N-1} of i) total segments. As Gauss knew when he was c.10 yo, the sum is (N-1)(N)/2.
