Taylor Wilson: Attempt 1 Question 2 (1 point)
Mark and Don are planning to sell each of their marble collections at a garage sale. If
Don has 5 more than 4 times the number of marbles Mark has, how many does Don
have to sell if the total number of marbles is 75?

Don has to sell 61 marbles.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

Don has to sell x marbles.

Mark has to sell y marbles.

The total number of marbles is 75:

This means that:

Since we want to find x.

Don has 5 more than 4 times the number of marbles Mark has

This means that:

Since

Don has to sell 61 marbles.

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
