The number on two consecutively numbered gym lockers have a sum of159. what are the locker numbers. Use comma to separate the an
svlad2 [7]
The answer is 79 and 80.

x - the number of the first locker
x + 1 - the number of the consecutive locker
Their sum is 159.

x + x + 1 = 159
2x + 1 = 159
2x = 159 - 1
2x = 158
x = 158 / 2
x = 79


x - the number of the first locker:                      x = 79
x + 1 - the number of the consecutive locker    x + 1 = 79 + 1 = 80

Diego is solving the inequality 100 − 3x ≥ -50. He solves the equation 100 − 3x = -50 and gets x = 50. What is the solution to t
ZanzabumX [31]

Answer:

x≤50

Step-by-step explanation:

100-3x≥-50

subtracting 100 at both side on inequality

-100+100-3x≥--50-100

-3x≥-150

Dividing both sides by 3

-3x/3≥-150/3

-x≥--50

Adding 50 on both sides

-x+50≥-50+50

-x+50≥0

Adding x on both sides

-x+x+50≥0+x

50≥x

so,

x≤50

jarptica [38.1K]
21 picks
altogether (2x+5x)=21
7x=21
x=3
2*3=6 orange picks

or
x=orange, y = greens
x+y=21
x/y=2/5,---->   y=5x/2
x+5x/2=21
2x/2+5x/2=21
7x/2=21
7x=42,
x=6  orange picks
