sea level =0 A submarine is 120ft below sea level it climbs 50 ft towards sea level where the submarine comparrf to sea level answer choices A is 70 ft b is -170ft c is -70ft​

Step-by-step explanation:

120 below we can use a model to figure this out.

sea level is 0

the submarine goes 120 down, so its -120

it goes up by 50, so now its 70

no other obstacles, 70 or A is your answer.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
