Bags of sugar come in 3 sizes.
kirill115 [55]

Answer:

cost per gram of small bag ≅ 4.119 p

cost per gram of medium bag ≅ 3.686 p

cost per gram of large bag ≅ 3.517 p

Step-by-step explanation:

cost per gram of small bag = 325 / 79

                                             = 4.119

cost per gram of medium bag = 575 / 156

                                                  = 3.686

cost per gram of large bag = 1150 / 327

                                             = 3.517

PLEASE HELP!!! THX

Answer:  1) Product property of logarithm,

2) Subtraction property of logarithm

3) Equality property of logarithm

Step-by-step explanation:

By the Product property of logarithm,

log a + log b = log(a.b)

And, By the Subtraction property of logarithm

log a - log b = log(a/b)

Also, by the equality property of logarithm,

log(a) = log(b) ⇒ a = b

Given expression,

log_2(5)+log_2(x+2)-log_2(x+1)=log_2(7)                                                                

\implies log_2(5(x+2))-log_2(x+1))=log_2(7)  (Product property of logarithm)

\implies log_2(\frac{5(x+2)}{2(x+1)})=log_2(7)  (Subtraction property of logarithm)

\implies \frac{5(x+2)}{2(x+1)}=7   ( Equality property of logarithm )

\implies 5(x+2)=7(x+1)    ( Multiplicative property of equality )

\implies 5x+10=7x+7  ( Distributive property of equality )

\implies 3=2x    (subtraction property of equality )

x=\frac{3}{2}       (division property of equality )
