Marcus can buy 0.3 pound of sliced meat from a deli for $3.15 how much will 0.7 pound of sliced meat cost?

 The required cost of 0.7 pounds of sliced meat is $7.35.

Step-by-step explanation:  Given that Marcus can buy 0.3 pound of sliced meat from a deli for $3.15.

We are to find the cost of 0.7 pound of sliced meat.

We will be using the UNITARY method to solve the problem.

We have

the cost of 0.3 pound of sliced meat = $3.15.

So, the cost of 1 pound of sliced meat will be

Therefore, the cost of 0.7 pound of sliced meat is

Thus, the required cost of 0.7 pounds of sliced meat is $7.35.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
