3/4 divided by 2
Please Help!!!
Solve x + x + 2 + 2x = -2.
1
-1
0
-2
Answer:
The answer is b: -1
Step-by-step explanation:
x + x + 2 + 2x = -2
Collect like terms
x + x + 2x = -2 - 2
4x = -4
Divide both sides by 4
x = -4/4
x = -1
Answer:
as follows
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
let the number of rounds of golf played for the cost to equal be x.
-It costs $35/ round when the membership of $500 is paid, hence, total annual cost is:
#When membership is not paid, the annual cost is expressed as:
#Since the cost should be equal after x rounds, we equate the two to solve for x:
Hence, Mr Bailey has to play 20 rounds of golf for the cost in both scenarios to be equal.
(x, y ) = (- 6, 3 )
Since both equations express y in terms of x, we can equate them
2x + 15 = - x + 1
( add x to both sides )
x + 15 = 1 ( subtract 15 from both sides )
x = - 14
( multiply both sides by 3 and divide by 7 )
x = ( 3 × - 14 )/7 = - 6
substitute x = - 6 into either of the 2 equations for y- coordinate )
y = ( 2 × - 6 ) + 15 = 3
solution : (x, y ) = ( - 6, 3 )
