Answer:
D) 3
Step-by-step explanation
The stem of 3 would have 3 leaves of (0, 1, and 4) from the numbers -> (34, 30, and 31)
Answer:
7 units
Step-by-step explanation:
Distance between 2 points
=
Thus, distance PQ

Or you could simply take 8-1= 7 since both points have the same x-coordinate. Thus, PQ is a vertical line and the distance between them is due to the difference in their y-coordinate.
Number of toothpicks required per student = At least 9
Total number of students = 30
Number of toothpicks required for the entire class = At least 9 × 30 = At least 270
Number of toothpicks in the bag in the class storage room = 50
Additional number of toothpicks required to be bought to make sure there are enough toothpicks = 270 - 50 = 220
Hence, she needs to buy 220 toothpicks.
Let the n-th term be called

We see that if we choose

then the other numbers follow the pattern

(see :

)
Hence the sequence will be
Answer:
See steps below
Step-by-step explanation:
-3(2x+7)=-29-4x
Use the distributive property
-6x-21=-29-4x
Add 21 to each side
-6x=-8-4x
Add 4x to both sides
-2x=-8
Divide by -2
x=4
