-2x+8.1y
+9x-5.3y
________
get the answer 7x+2.8y
Answer:
T=120(P+B)
Step-by-step explanation:
If a pack holds 120 tissues, then P packs will hold (P×120) tissues
This implies,
1 pack : 120 tissues
P packs : 120P tissues
Also, if a box holds 120 tissues, then B boxes will (B×120) tissues
This implies,
1 box : 120 tissues
B boxes : 120B tissues
Writing a formula in terms of T, where T is the total we obtain,
T=120P +120B
Using the idea of factorization we obtain
T=120(P+B)
D. X= -4 y= 3 is the correct answer
(a)
Total amount = SI + Amount
= 90 + 1800 = $1890
(b)
Total amount = SI + Amount
= 936 + 2600 = $ 3236
(c)
Total amount = SI + Amount
= 93.75 + 3125 = $ 3,218.75
