Answer:
Someone has to attend 6 classes in a month and it will cost $60.
Step-by-step explanation:
The yoga studio offers memberships that cost $60 per month for unlimited classes.
The studio also accepts walk-ins, charging $10 per class.
If someone attends x number of classes in a month, then in the second plan it will cost $10x which has to be equal to $60.
So, 10x = 60
Therefore, if someone attend classes in a month, the two options cost the same total amount.
The total amount of charges will be $60. (Answer)
Answer:
Step-by-step explanation:
In each case, the multiplier of x is (1 + fractional change). The fractional change is negative for a discount or draining. It is positive for any addition or increase.
a) (1 -0.18)x = 0.82x . . . . 18% = 0.18
b) (1 +0.18)x = 1.18x
c) (1 -3/10)x = 7/10x
d) (1 +3/10)x = 13/10x
Answer:
x = larger number
Let y = smaller numer
(1) x + y = 48
(2) x = y + 14
Solving (1) for x:
x = 48-y
Substituting this into (2) and solving for y:
48-y = y+14
48-2y = 14
-2y = -34
y = 17
x = 48-y = 31
So, the smaller number is 17 and the larger number is 31

Answer:
(x + 2)(x² - 2x + 4)
Step-by-step explanation:
x³ + 8 ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²), thus
x³ + 8
= x³ + 2³
= (x + 2)(x² - 2x + 4)
