Answer:y = 2/3
Step-by-step explanation:
2x + y = 10
x - y = 4
-----------------add
3x = 14
x = 14/3
x - y = 4
14/3 - y = 4
-y = 4 - 14/3
-y = 12/3 - 14/3
-y = -2/3
y = 2/3 <==
Answer:
ok i'll see what i can do
Step-by-step explanation:
Answer:
A.
x + y = 28
1.68x + 2.44y = 54.64
Step-by-step explanation:
Let x = paperback books and y = hardback books
x+y =28
We know that paperbacks cost 1.68 and hardback cost 2.44
1.68x + 2.44y = 54.64
We have 2 equations and 2 unknowns
x+y =28
1.68x + 2.44y = 54.64
Answer:
11/24 - 6/24 = 5/24
Step-by-step explanation:
Common denominator is 24
24 * 1 = 24 11 * 1 = 24 11/24
4 * 6 = 24 1 * 6 = 24 6/24
New fractions are 11/24 and 6/24
Subtract them
11/24 - 6/24 = 5/24
It would be B, because BC does not necessarily have to be equal to CE, as they are not congruent
