The answer is (1,1). If you need an explanation why I will be happy to help :)
Cost of dried fruit per pound=2.5 $/pound
cost of nuts per pound =2 $/pound
total cost=225$ =cost of dried fruit +total cost of nuts
To find the cost of dried fruit we need to multiply cost of dried fruit per pound and the number of bounds hence 2.5 x where x is the number of bounds
which is the total cost of dried fruit and consequently 2y is total cost of nuts where y is the weight of nuts in pound
Answer:
I thinks it's that last one
Answer:
281
Step-by-step explanation:
8 + 7(42–3) =
= 8 + 7(39)
= 8 + 273
= 281
S(x) = x - 7; t(x) = 4x² - x + 3
(t · s)(x) = (4x² - x + 3)(x - 7) = (4x²)(x) + (4x²)(-7) - (x)(x) - (x)(-7) + (3)(x) + (3)(-7)
= 4x³ - 28x² - x² + 7x + 3x - 21 = 4x³ - 29x² + 10x - 21
