Step-by-step explanation:

First distribute 7 into the first equation. (4a+3b-6) Multiply each coefficient and the constant by 7.

28a+21b-42

Then do the same for -3 and (3a-2b+4).

-9a+6b-12

Rewrite the equation 28a+21b-42-9a+6b-12.

Haeden observed that 65% of her coworkers prefer the local talk news radio station. If 28 of her coworkers do not prefer talk ne
vekshin1

Part A


Let x represent the number of coworkers who prefer the talk news radio.


65% prefer the talk news radio,



100-65=35% will be the percentage that corresponds to coworkers who do not prefer the talk news radio.


Part B


We apply ratio to find x.




65:x



35:28


Hence number that corresponds to 65% will be greater than 28.


If more, less will divide.


This implies that,



x=\frac{65\times 28}{35}=52


Hence 52 of her coworkers prefer the local news talk station.

Mel's Furniture received an invoice dated September 27 for 5 bedroom sets at $3,000 each. The invoice indicated a chain discount
LenKa [72]

Answer: $12,916.70

Step-by-step explanation:

Given the following:

Invoice received :

Bedroom set = 5

Cost per set = $3,000

Chain discount = 5/8/3

Freight cost = $200

If Mel pays within the discount period:

Chain discount given = 5/8/3

Therefore, net equivalent price rate equals:

(1 - 0.05) × (1 - 0.08) × (1 - 0.03) =

0.95 × 0.92 × 0.97 = 0.84778

Net price = total cost × 0.84778

($3000 × 5) × 0.84778

$15000 × 0.84778 = $12,716.7

Net equivalent price + FOB Shipping

$12,716.7 + $200 = $12,916.70
