143220 pencils
55 days
7 schools
124 pencils per case
143220 / 124 = 1155 total cases
1155 / 55 = 21 cases per day
21 / 7 = 3 cases per school per day
January has 31 days
31 * 3 = 93 cases were delivered each day
Answer:
Step-by-step explanation:
The associative property states that you can add or multiply regardless of how the numbers are grouped.
Answer:
y=x(t)+y-int
Step-by-step explanation:
Where:
Y= distance
x=speed
t=time
y-int= starting height
If you can post a rate and starting height I can answer part B
Keep in mind if she is traveling down then y-int will be 0<x and the rate will be negative
Y = mx + b....for b
subtract mx from both sides
y - mx = b <==
Answer: PN= 20 in.
Step-by-step explanation:
Given: In triangles PMN and QSR :
Length of P N ≅ Length of RQ (1) [ '≅' → Sign of congruence]
Length of QS ≅ Length of PM
Length of MN ≅ Length of RS
By SSS congruence rule
ΔPMN ≅ ΔQSR
Since Length of QR =20 in. [Given]
From (1)
Length of PN= 20 in. [Congruent means exactly equal]
