Answer:
There are 45 stamps from Africa
Step-by-step explanation:
10% of 150 is 15
30% of 150 is 45
15*3 = 45
-7x + y = -6 |add 7x to both sides
y = 7x - 6
the slope: m = 7
the y-intercept: y = -6
You need to replace x with 5 so it will be…
[3(5) + 4] - (2 - 5)
(15 + 4) - (-3)
19 + 3
22
100 and 49 make a difference of 51.
100 - 49 = 51
10 x 10 = 100
7 x 7 = 49
