Step-by-step explanation:
the midpoint of the line segment joining the points (-3,-1) and (-7,6) :
X = (-3-7)/2= -10/2 = -5
Y = (-1+6)/2 = 5/2 = 2.5
=> (-5, 2.5)
The answer is m = 7/5 (decimal form is 1.4)
Answer:
3x + 1 = 7
x = 2
Step-by-step explanation:
equation for the hanger diagram
3x + 1 = 7
Subtract 1 from both sides
3x = 6
Divide both sides by 3
x = 2
What do you have to estimate?
We've got the first number, so now we need the others.
There is 1 possibilty for the first digit, 10 for the middle ones, and 2 for the last one.
1*10*10*2=200
