Answer:
After 5 months
Step-by-step explanation:
Step one:
given data
LA Fitness charges a registration fee of $75 plus $35.75 per month for members
let the number of months be x
and the total charges be y
total is
y= 75+35.75x----------1
Gold's Gym charges a registration fee of $164 plus $17.95 for members
let the number of months be x
and the total charges be y
total is
y= 164+17.95x----------2
Step two:
equate 1 and 2
75+35.75x= 164+17.95x
solve for x
35.75x-17.95x=164-75
17.8x=89
divide both sides by 17.8
x=89/17.8
x=5 months
Answer:
Slove For X
x= -1
Solve for Y
Y= 10/3
Step-by-step explanation:
SO I did Elimination method
To isolate X and to solve for it
x+3y=9
3x−3y=−13
Add these equations to eliminate y:
4x=−4
Solve for X
x=-1
Now plug x back in to solve for y
Terrace, because area= length (l) * width (w). Since terrace's room is 9 by 8, you multiply 9*8 which gives you 72ft squared. Jody's bedroom id 7*10 which gives you 70 ft squared. 72 is greater than 70.
Answer: 14/3
Step-by-step explanation: (7/9) (6) = 54/9 = 14/3
Answer:
C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° = 
, cos45° = 
, thus
sin60° = 
= 
= ( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp = 
Now consider the right triangle on the right, using the cosine ratio
cos45° = 
= 
= ( cross- multiply )
x = × 
= 
→ C
