C=x+9, c+x=99, c=99-x

So we have two equations equal to c, c=x+9 and c=99-x, since c=c:

x+9=99-x

2x+9=99

2x=90

x=45, and since c=x+9, c=54

So Charlie weighs 54 kg and his brother weighs 45 kg.

Natasha_Volkova [10]

Answer:Cost per box: $95.94 ÷ (b)

            Cost per tile: [$95.94 ÷ (b)]÷ (t)

First, we are trying to find the cost of each crate. Since the whole order was $95.94, we have to divide. The answer to the cost per box is $15.99.

Second, we are trying to find the cost of each of the tiles in the crates. Since they are in each crate, we divide the crate price from the tiles. The answer of the cost per tile is $.80.

Hope this helped you out!

A stone is thrown upward from ground level. With what minimum speed should the stone be thrown so as to reach a height of 81 fee
butalik [34]
Use the kinematics equation:
v1^2-v0^2=2as
since v1=0 (at height of 81 ft), and a=g=-32.2, substitute values:

0-v0^2=2*(-32.2)(81 ft)
Solve for v0
v0=sqrt(2*32.2*81)=72.2 m/s
