A kiddy pool going over it’s limit so you have to subtract 4 liters to get to the safe level bar.
Answer: 17
Step by step : 146+2x=180
2x=34
X=17
Answer:
x = 0
y = 5
z = -5.
Step-by-step explanation:
X-5y-z=-20
-2x-y-6z=25
-x-4y-z=-15
Add equation 1 and 3:
-9y - 2z = -35 .......... A
Multiply the first equation by 2:
2x - 10y - 2z = -40
Now add this to equation 2:
-11y -8z = -15.............B
Now multiply equation A by -4:
36y + 8x = 140.........C
Add equations B and C:
25y = 125
y = 5.
Substitute for y in equation A:
-9*5 - 2z = -35
2z = -45 + 35 = - 10
z = -5.
Now find x by substituting for y and z in the first equation:
x - 5(5) - (-5) = -20
x - 20 = -20
x = 0.
The average of Earth's aphelion and perihelion (nearest and farthest
distances from the sun) is 149,553,262 km.
The average of Saturn's aphelion and perihelion (nearest and farthest
distances from the sun) is 1,426,666,422 km.
That's about 4.6% less than 10-times Earth's number.
The difference is 6.887 x 10⁷ km . (rounded)
Integer 1 = n
integer 2 = n + 1
integer 3 = n + 2
n + (n + 1) + (n + 2) = 141
3n + 3 = 141
3n = 141 - 3
3n = 138
n = 138/3
n = 46 --(1st integer)
n + 1 = 46 + 1 = 47 --(2nd integer)
n + 2 = 46 + 2 = 48 --(3rd integer)
so the smallest integer is 46
