First you would combine like terms on each side of the equation It would look like this... 4X+8= 4X-13
Then you would add 13 to both sides, the 13 on the right side of the equation would cancel out and the 8 would become 21. It would look like this... 4X+21=4x.
Now you would subtract 4X from both sides. The 4's Would cancel out which would leave you with 21=X

Forth time I had to ask this!!
lubasha [3.4K]
A.) Yes you can, the expression would be (2.95 x Y) + 4 = X
B.) (2.95 x 24) + 4 = $74.80
C.) (2.95 x 57) + 4 = X
2.95 x 57 = 168.15 + 4 = 172.15
so basically they can buy 57 books without going over $175

Joel has a bag with 128 pieces of candy in it. He gives his sister 25% of the candy. How many pieces of candy does Joel give his
Charra [1.4K]

Answer:

Joel  \:  \: gave \:  \:  his \:  \:  sister \:  \:  32  \:  \: pieces\:  \: of \:  \:  candy

Step-by-step explanation:

\frac{x}{128}  =  \frac{25}{100}

(x)100 = (25)128

(x)100 = 3200

\frac{(x)100}{100}  =  \frac{3200}{100}

x =  \frac{3200}{100}

x = 32

Joel  \:  \: gave \:  \:  his \:  \:  sister \:  \:  32 \:  \: pieces  \:  \: of \:  \:  candy

A rocket is launched in the air. Its height in feet is given by h (t) = -16t^2 + 104t where t represents the time in seconds aft
Dafna11 [192]

Looking at the function h(t), it is a polynomial function.

The domain of this type of function usually is all real numbers.

But in this case, since the independent variable t represents the time, its value can't be negative, it usually starts at t = 0.

Therefore the appropriate domain for this situation is all non-negative numbers:

\begin{gathered} t\geq0\\ \\ or\\ \\ \text{ }[0,\infty) \end{gathered}
