Answer:
x=±9 and y=10
Step-by-step explanation:
so for x
we have
x²+(-4)=32
x²=36
x=±9
for y:
y+y-4=y+6
2y-4=y+6
y=10
Answer: 60,000
Step-by-step explanation: 24,000 plus 150% = 60,000
Answer:
Step-by-step explanation:
Assuming the same number of bowling and mini golf games are played, let x represent the total number of games played, either bowling or mini golf. let y represent the total cost of bowling. Let z represent the total cost of golfing
Bowling cost $2 to rent a club plus $5 per game. It means that the cost, y for x bowling games will be
y = 2 + 5x
Mini golf cost $5 to rent a club, plus $4 per game. It means that the cost, y for x mini golf games will be
z = 5 + 4x
For the total cost to be the same, we will equate both equations(y = zl
2 + 5x = 5 + 4x
5x - 4x = 5 - 2
x = 3
There would be 3 games before total cost would be the same
Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2x = 8 ( divide both sides by 2 )
x = 4
