Red blood cells are really small...

One number is BIG: 7.5×10^4 mm = 75,000 mm = 75 meters
The other number is really SMALL: 7.5×10^-4 = 0.00075 mm

The negative exponent moves the decimal left instead of right.

The first aircraft has 89 more seats than the second aircraft. The third aircraft has 31 fewer seats than the second aircraft. I

Valentin [98]

Answer:

I think number 1=209

number 2=120

number 3=89

Step-by-step explanation:

x= 1st aircraft

y=2nd aircraft

z=3rd aircraft

x=y+89

y=z+31

z=y-31

x+y+z=418

y+89+z+31+y-31=418

2y+89+z=418

2y+z=329

2y+(add z)

2y+y-31=329

3y=360

y=120

x=120+89=209

z=120-31=89

What is the slope of the line that contains the points (-1, 8) and (5, -4)

mylen [45]

Answer:

slope = - 2

Step-by-step explanation:

calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 1, 8 ) and (x₂, y₂ ) = (5, - 4 )

m = $\frac{-4-8}{5-(-1)}$ = $\frac{-12}{5+1}$ = $\frac{-12}{6}$ = - 2

If you want to make 10, you can take 3 from the 13 and add it to the 7. You will then have 10+10 which equals 20.
