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)

The graph of the equations was plotted using geogebra graphing and attached.

Nostrana [21]

102.
102 is the closest to a two digit number that is divisible by 2, 3, and 4.

Solving system of equations by substitution

weeeeeb [17]

Y=3x-10 and 3x+2y=16
y=3x-10
subsitute 3x-10 for y in other equation

3x+2y=16
3x+2(3x-10)=16
distribute
3x+6x-20=16
9x-20=16
add 20 both sides
9x=36
divide both sides by 9
x=4

sub back

y=3x-10
y=3(4)-10
y=12-10
y=2

x=4
y=2
(4,2) is soluiton
