Answer:
3 pencils
Step-by-step explanation:
since there are only 24 erasers and the packages have to be all the same, the greatest number of packages that can be made are 24. then you have to divide 72 into 24 to get an equal amount in each package.
Answer:
t=-8
Step-by-step explanation:
-2 (t- 1) = 18
Divide each side by -2
-2 (t- 1)/-2 = 18/-2
t-1 = -9
Add 1 to each side
t-1+1 = -9+1
t = -8

The answer to your question above, I will just illustrate it down.
<span>sqrt(3 x +7 ) = 1 - sqrt(x + 2 )
</span><span>square both sides:
3x + 7 = 1 -2sqrt(x = 2) + x + 2
Then it would become like this,
</span><span>2x + 4 = -2sqrt( x + 2 )
</span>Divide both sides by -2 to eliminate the -2 on the left side with sqrt.
Then <span>square both sides:
x^2 + 4x + 4 = x + 2
</span><span>x^2 + 3x + 2 = 0
</span><span>(x + 2) (x + 1) = 0
</span><span>x=-2, -1 there is no sqrt for-1
</span>so the answer is -2
