A hockey team scored 45 goals in its first 16 games. At this rate, how many goals would the team score in an 80 game season? A.

Goshia [24]

First you have to divide 45 by 16. that gives us 2.8125. then multiply 2.8125 by 80 to get 225.

Solve the equation (linear equation)

Leno4ka [110]

Answer: $x=\frac{37}{9}$

Step-by-step explanation:

By the negative exponent rule, you have that:

$(\frac{1}{a})^n=a^{-n}$

By the exponents properties, you know that:

$(m^n)^l=m^{(nl)}$

$(m^n)(m^l)=m^{(n+l)}$

Rewrite 4, 8 and 32 as following:

4=2²

8=2³

32=2⁵

Rewrite the expression:

$(2^2)^{(x-7)}*(2^3)^{(2x-3)}=\frac{32}{2^{(x-9)}}$

Keeping on mind the exponents properties, you have:

$(2)^{2(x-7)}*(2)^{3(2x-3)}=32(2^{-(x-9)}$

$(2)^{2(x-7)}*(2)^{3(2x-3)}=(2^5)(2^{-(x-9)})\\\\(2)^{(2x-14)}*(2)^{(6x-9)}=(2^5)(2^{(-x+9)})\\\\2^{((2x-14)+(6x-9))}=2^{(5+(-x+9))}$

As the bases are equal, then:

$(2x-14)+(6x-9)=5+(-x+9)\\\\2x-14+6x-9=5-x+9\\\\8x-23=14-x\\9x=37$

$x=\frac{37}{9}$
