= The average score of Karl's first four math tests is 72 points. After the fifth and the sixth tests, his average score increas
mylen [45]

Answer:

83 points

Step-by-step explanation:

-The formula for average is given as:

\bar X=\frac{1}{n}\sum{x_i}\\\\x_i=Individual \ Test \ scores\\n=number \ of \ scores

Let a be his 5th score and (a+4) of the 6th

#We subtract the sum of the first 4 tests from the 6, to get the sum of the 5th and 6th tests:

(6^{th}+5^{th})=\bar X n_6-\bar X n_4\\\\=75\times 6-72\times 4\\\\=162

#We substitute for the 5th and 6th to solve a:

5^{th}=a\\6^{th}=a+4\\\\a+(a+4)=162\\\\2a=158\\\\a=79\\\\6^{th}=a+4=79+4=83

Hence, Karl score 83 points in his 6th test.

If NQZ ~ CBK, find BK<br><br> Look at picture
nevsk [136]

Answer:

BK=39/7

Step-by-step explanation:

because NQZ~CBK

so BK/QZ = TZ/KF

(4x+1)/(2x+7) = 27/45 = 3/5

5(4x+1) = 3(2x+7)

20x + 5 = 6x + 21

14x = 16

x = 8/7

=> BK = 4(8/7)+1 = 39/7
