HELP number 12 pls i do nor have long more

Dian has $250 originally.

Step-by-step explanation:

Let the total money Dian has originally = $S

Dian gave of her total money to Justin,

Money given to Justin =

Money left with Dian = S -

                                   =

                                   =

Since Dian has $150 left then the equation will be,

S =

S = $250

Therefore, Dian has $250 originally.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
