Answer:
It’s the third one
Step-by-step explanation:
-1.1x+6.4>-1.3
-1.1x>-1.3-6.4
-1.1x>-7.7 multiplied by -1 gives 1.1x<7.7
Divided by 1.1 you get x<7
The graph of the equations was plotted using geogebra graphing and attached.
Let x represent the hours weightlifting and y represent the hours doing cardio exercises.
Since he spend a maximum of 20 hours, hence:
x + y ≤ 20 (1)
Also, he spends at least 8 of those hours weightlifting, hence:
x ≥ 8 (2)
He wants to spend no more than 15 hours doing cardio exercises, this is:
y ≤ 15 (3)

Answer:
-12p-20
Step-by-step explanation:
{-12-6p-(-2)}−12−6p−(−2)
-12-6p+2−12−6p+2
-12p-20
Answer: The equation that would help members to find how much they would pay per month is
40 + 12x = 460
Step-by-step explanation:
Let x represent the amount of money that members would pay per month.
Let y represent the number of months for which a member uses the gym.
There is a fee of $40 when you join, and the rest is paid monthly. This means that the cost of using the gym for x months would be
40 + xy
A one year membership to metro gym costs $460. Therefore are 12 months in a year. Therefore,
40 + 12x = 460
12x = 460 - 40 = 420
x = 420/12 = 35
The equation that would help members to find how much they would pay per month is
Earth volume: (3/4).π.(6371)³ = 1,0832x10¹² km³
Pluto volume: (3/4).π.(1171)³ = 6,555,189,765 km³
How many spheres the size of Pluto does it take to have the same volume as earth?
volume Earth/ volume Pluto = 1,0832x10¹² / 6,555,189,765 = 165.25
