Mark and Don have to sell 11 and 59 marbles respectively.
<em><u>Explanation</u></em>
Lets assume, the number of marbles Mark has is
As, Don has 4 more than 5 times the number of marbles mark has, so the number of marbles Don has
Question says that the total number of marbles is 70. So, the equation will be...
<em>So, the number of marbles Mark has = 11 </em>

Answer:
<u>P (not white) = 2/3</u>
Step-by-step explanation:
<u>Probability (not white)</u>
- No. of non-white marbles / Total marbles
- 8 + 14 + 10 / 8 + 16 + 14 + 10
- 32/48
- <u>2/3</u>
Answer:
y = 2/5
Step-by-step explanation:
Answer:
slope of the line is zero
Step-by-step explanation:
Answer:
x=0, y=-2
Step-by-step explanation:
Let x=3y+6 be equation 1
and 2x-4y=8 be equation 2
sub equation 1 into equation2,
2(3y+6)-4y=8
6y+12-4y=8
2y=-4
y=-2
sub y=-2 into equation 1,
x=3(-2)+6
x=0
sub is an abbreviation for substitute
