Answer:
10 years.
Step-by-step explanation:
Let total age of five people be x;
x/5 = 40
x = 40*5
x = 200.
Let age of new person be y;
(200 + y)/ 6 = 35
200 + y = 210
y = 210-200
y= 10.
The age of the new person is 10.
See ya!
Hope it helps!
Answer:
0 < t <= 4
Step-by-step explanation:
<h2>
ONLY FLIP THE INEQUALITY SIGN WHEN MULTIPLYING OR DIVIDING BY A NEGATIVE NUMBER</h2>
-2 < 3t - 2 <= 10
-2 + 2 < 3t - 2 + 2 <= 10 + 2
0 < 3t <= 12
0/3 < 3t/3 <= 12/3
0 < t <= 4

Answer:
(0 , -1)
Step-by-step explanation:
WR = 4 + 2 = 6
WS = 1/3 x WR = 2 .... the point of 1:2 of WR
S (-2 + 2 , -4) i.e. (0,4)
The same reason: RQ = 1/3 x RY = 1/3 x (5 + 4) = 3
Q (-4 , -4 + 3) i.e. (-4, -1)
QP // RW
p (0 , -1)
