What does -2/3 (x + 5) + 4 (x + 5) - 10/3 (x + 5) equal
Kitty [74]

Answer: 0

Step-by-step explanation:

-\frac{2}{3}(x+5)+4(x+5)-\frac{10}{3}(x+5) = ?

-\frac{2}{3}x-\frac{10}{3}x+4x+20-\frac{10}{3}x-\frac{50}{3} = ?

(-\frac{2}{3}x+4x -\frac{10}{3}x) +(-\frac{10}{3}+20-\frac{50}{3})=?

(-\frac{12}{3}x+4x)+(-\frac{60}{3}+20)=?\\  (-4x+4x)+(-20+20)=?\\0+0=0

Please Help!! Whoever helps and gets it correct gets Brainliest and 5 star rating!!
grandymaker [24]

Answer:

the reasoning states that "all the numbers begin with a 7 or an 8"

however this is not accurate as they can be in different placements

which can make a big difference in the total estimate.

for example:

the number could've been an 8, or an 80

they both begin with an 8

however have totally different values and could have messed up the total estimated number.

hope this helps :D
