Answer:
take away the 15 and 8
Step-by-step explanation:
12 plus 5 =17
Answer: 16
Step-by-step explanation:
From the question, we are informed that there are 25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple and that one marker is drawn out of the bag, then put back in.
The probability of picking a blue marker will be: = 5/25 = 1/5
Therefore, the number of times that a blue marker will be expected to be picked in 80 draws would be:
= 1/5 × 80
= 16 times
Answer:
K = 11
Step-by-step explanation:
3(k - 6) = 15
3k - 18 = 15
3k = 15 + 18
3k = 33
K = 33/3
K = 11
Thus, the value of K is 11
Answer:
Step-by-step explanation:
Given
Required
Solve for A
Simply substitute 18 for b and 30 for h
Hence:
The area is
Plug in the first equation into the he second equation
3x-(2x+7)=-9
3x-2x-7=-9
x-7=-9
x=-2
plug in x=-2 into the first equation
y=2(-2)+7
y=-4+7
y=3
answer: (-2,3)
