A thousand
a kilo means a thousand of anything such as kilometer or kiloton
Using the formula for the nth term of an arithmetic sequence we can write:
80 + (n - 1)2 = 65 + (n - 1)5
80 + 2n - 2 = 65 + 5n - 5
3n = 18
n = 6
The answer is 6 months.
Answer:
4 liters are greater than 1 American Gallon
4 liters are less than 1 UK gallon
Step-by-step explanation:
1 American gallon equals 3.78541 liters.
So 4 liters are greater, whereas
1 British gallon equals 4.546090 liters.
In this case 1 UK gallon is greater.
Answer:
y=3,x=1.3,z=6.2 :)
Step-by-step explanation:
y=3,x=1.3,z=6.2 :)
So, we have:
: x+y+z=10 [equation 1]
: 5x+3y=14 [equation 2]
: x−2y+z=2.5 [equation3]
(I'm going to assume that you know how to solve equations with 2 variables)
1. eliminate a variable to get 2 variables
Let's reverse equation 2:
-x+2y-z= -2.5
and take equation 1, to try to eliminate "z"
x+y+z=10
add up the 2 equations to get:
3y=7.5
and solve to get
y=2.5
2. substitute what we already solved into another equation
Luckily, equation 2 only has 2 variables, and one is y, so we can sub it in.
5x+3y=14 --> 3x+3(7.5)=14
solve to get
x=1.3
3. Substitute both of our variables in to get the final variable: z
Let's take the first equation.
x+y+z=10 --> 1.3+2.5+z=10
solve to get
z=6.2
I hope this helps you!
Answer:
(-.5, 0)
Step-by-step explanation:
y ---- 2÷2=1, y-1= 1-1=0
x ---- 3÷2 =1.5, x-1.5= 1-1.5= -.5
