Answer:

2) y = x - 4

y = -x + 2

=> x - 4 = -x + 2

=> 2x = -6

=> x = -3

=> y = -3 - 4 = -7

3) y = 3x + 1

y = 5x - 3

=> 3x + 1 = 5x - 3

=> 2x = 4

=> x = 2

=> y = 3(2) + 1 = 7

4) 2x + y = 8 => y = -2x + 8

y = x - 7

=> -2x + 8 = x - 7

=> 3x = 15

=> x = 5

=> y = 5 - 7 = -2

Answer:

Step-by-step explanation:

The given expression is

$\frac{2^{\frac{11}{2} }\times 2^{-7}\times 2^{-5}}{2^3\times 2^{\frac{1}{2} }\times 2^{-10}}$

Recall and use

$a^m\times a^n=a^{m+n}$

$\frac{2^{\frac{11}{2} -7-5}}{ 2^{3+\frac{1}{2} -10}}$

$\frac{2^{-\frac{13}{2}}}{ 2^{-\frac{13}{2}}}$

Same bases are dividing, so we write one base and subtract the exponent.

$2^{-\frac{13}{2}+\frac{13}{2}}$

$2^0=1$

Zena and Audrey are on the same bowling team. The sum of their averages is 299. If Zena's average is 13 pins greater than Audrey

Lisa [10]

Easier than it looks, all you have to do is first subtract 13 from 299. You should get 286. Then, you just divide this number by two to get 143. Finally, since it asks for ZENA'S average, you add the 13 back to 143 to get the final answer of the average number of pins Zena took down, which is 156!
