Answer:
Each friend gets 0.7 cookie
8 cookies
Step-by-step explanation:
A.
Number of cookies = 7
Number of friends = 10
how much cookie will each friend receive?
Number of cookie each friend get = number of cookies / number of friends
= 7/10
= 0.7 cookie
Each friend gets 0.7 cookie
B.
If each friend 1 1/2 cookies
how many more cookies would she need?
Total number of cookies needed = 1 1/2 × 10
= 3/2 × 10
= 30/2
= 15 cookies
She already has 7 cookies
Number of cookies needed more = 15 cookies - 7 cookies
= 8 cookies
Answer:
-1/3
Step-by-step explanation:
y = 3x+7
This is in the form y = mx+b
The slope is m so it is equal to 3
Perpendicular lines have slopes that are negative reciprocals
m perpendicular = - (1/3)
Answer:
8, 40 , 50
Step-by-step explanation:
the measure of A is 90°
so 5x + 7x - 6 = 90
now.. to find the x
5x + 7x - 6 = 90
5x + 7x = 90 + 6
12x = 96
x = 96/12
x = 8
so the measure of angle A1 is (5*8) = 40
the measure of angle A2 is (7*8-6) = 50
finaly the angle A is (50+40) = 90
