Answer:
Step-by-step explanation:
x + y = 61........(1)
x - y = 25..........(2)
Adding (1) and (2)
2x = 86
x = 86/2
x = 43
And x + y = 61...(1)
43 + y = 61
y = 61 - 43
y = 18
The number are 43 and 18
Answer:
v = - 3
Step-by-step explanation:
Given
v = u + at ← substitute u = 2, a = - 5, t = 1 into the expression
v = 2 + (- 5 × 1) = 2 + (- 5) = 2 - 5 = - 3
The volume:
Pi x r^2 x h
V = pi x 12^2 x 7
V = 1008pi units^3
The answer would be a
hope it helps.
Perpendicular line : m × m1 = -1
from y =2x-3 , m=2
m1•2 = -1
m1 = -1/2
substitute P in --> y= mx +c
5 = -1/2 (-6) + c
5-3 = c
c = 2
y = -1/2x - 1
