A + E + N = 122
E = 2N
A = 7 + E....A = 7 + 2N
(7 + 2N) + 2N + N = 122
5N + 7 = 122
5N = 122 - 7
5N = 115
N = 115/5
N = 23 <== North America
E = 2N
E = 2(23)
E = 46 <== Europe
A = 7 + E
A = 7 + 46
A = 53 <=== Africa
Answer:
A. 11•(8 + 7)
B. 8•(11)-7•(11)
C. 11•(7) + 11•(8)
Step-by-step explanation:
The commutative property of multiplication lets you swap the order of the factors in the product:
(8 +7)•11 = 11•(8 +7)
The distributive property lets you eliminate parentheses:
(8 +7)•11 = 8•11 +7•11
And the commutative properties of addition and multiplication let you rearrange this sum of products to ...
(8 +7)•11 = 11•7 +11•8
The y intercept is what the y value is when x is 0.
Set X to 0 and solve:
-2/9(0) + 1/3
0 + 1/3 = 1/3
The y-intercept is 1/3
