Hello!

You can solve this algebraically

15 - 13(2x + 6) < 15 - 3(6x - 7)

Subtract 15 from both sides

-13(2x + 6) < -3(6x - 7)

Distribute the -13

-26x + -78 < -3(6x - 7)

Distribute the -2

-26x - 78 < -18x + 21

Add 18x to both sides

-8x - 78 < 21

Add 78 to both sides

-8x < 99

Divide both sides by -8

x < -12.375

The answer is -12.375

Hope this helps!

Answer:

Just Between Friends

The percentage of consignors who receive a check for more than $370 is:

= 16%.

Step-by-step explanation:

Mean of consignor check, μ = $480

Standard deviation, σ = $110

Value of check received, x > $370

Solution: find the z-score to determine the percentage of consignors who receive a check for more than $370:

z = (x-μ)/σ

z= ($370 - $480)/$110

z = -$110/$110

z = -1.00

Percentage of consignors who receive a check for more than $370

= 0.15866

= 0.16

= 16%

if you add 55% and 45% the total is 100% so 45/100 are girls.  35% of the girls scored and A  so 35/45  is the probability that it is a girl chosen or 7/9. the probability is 7 out of 9.
