Answer:
(3,2)
Step-by-step explanation:
The system is
x + y = 5
x -y = 1
Add the equations to eliminate y
2x = 6----->x=3
Substitute this value in any equation
3+y = 5----->y=2
The solution is (3,2)
Answer:
c= 61m
Step-by-step explanation:
using Pythagoras theorem, sin33°=a/c
sin33°=33/c
using tables, sin33°=0.5446
substituting,
0.5446=33/c
cross multiply
0.5446*c=33
divide both sides by 0.5446
c=33/0.5446
c=60.5949321
c=61m (to the nearest whole number)
Answer:
The correct anser is option
B. 2x + 2 = 18
Step-by-step explanation:
Let the number of hot dogs eaten by the runner up be represented by x
If Dave ate 2 more than twice x, this means that the number eaten by him = 2x + 2
Since the total number of hot dogs eaten by Dave is 18
Therefore, the equation will be
2x + 2 = 18
So the number of hot dogs eaten by the runner-up is determined by solving for x
2x= 18-2
2× = 16
x = 16/2
x = 8
The runner up are 8
While Dave are
2×8 + 2 = 18.
