Answer:
Step-by-step explanation:
Lets say that I have 9.6+78.9 to estimate, we need to just calculate what it rounds up to, 9.6 rounds up to 10 and 78.9 rounds of to 79, our answer will be at round 89, this is the basic way of how to round it up. Btw the answer is 88.5
It is.
To be divisible by 6, it has to be divisible by 2 and 3.
It's an even number so divisible by 2.
The sum of the digits is divisible by 3 so number is divisible by 3.
Slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
we are given the points (-2,7) and (x,2)
slope is -1/3
so
(x,y)
(-2,7) and (x,2)
x1=-2
y1=7
x2=x
y2=2
slope=(2-7)/(x-(-2))=-1/3
slope=(-5)/(x+2)=-1/3
multiply both sides by (-3)(x+2) (basically cross multiply)
15=x+2
minus 2 both sides
13=x
x=13
the value of x is 13
