Answer:

Per tier is 3

Step-by-step explanation:

5-2x=-4x+9

Since each side is same

5=-2x+9

-2x+4=0

2x=4

x=2

And 5-4 is 1

1+1+1 is 3

Factor -1(x^(2)-3x-4) and pls show steps
soldi70 [24.7K]

Answer:(-x-1)(x-4)

Step-by-step explanation:

-1(x^{2} -3x-4)

factor the equation (multiples of 4 are 1 and 4 and 2 and 2) 4-1=1 so the factor you want to use are 1 and 4

-1(x +1)(x-4) --  -4+1=3

distribute the -1 into the first factor

(-x-1)(x-4)

jack wants to know how many families in his small neighborhood of 60 homes would help organize a neighborhood fund-raising party
valkas [14]
No, that would be an invalid inference because he actually sampled from only half of the total population not the entire population.

so 12% of the 50% he sampled would be valid, but since he did not use the entire population, the results cannot affect all of them.<span />

This is a true or false answer please help me**
Nitella [24]

Answer:

5False

6  true

7 true

Step-by-step explanation:

5 Complementary angles add to 90 degrees not 180 degrees

6  40+50 = 90 so they are complementary

7 Supplementary angles add to 180

   145+x = 180

Subtract 145 from each side

145-145 +x = 180-145

   x = 35
