Answer:
the answer is the second one 480ft^3

let's plug in the value of y :
Answer:
B. 6
Step-by-step explanation:
D. 12 cant be multiplied to get 18
C. 4 cant be multiplied to get 18
A. 2 is a common factor of 12 and 18 but not the greatest.
B. 6 times 2 is 12 and 6 times 3 is 18 so 6 is the greatest common factor.
absolute value means always positive
|-1|+|0.8|
1 + .8
1.8
Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
3x +2y = 5 → (1)
x - 2y = - 1 → (2)
Adding the 2 equations term by term will eliminate the term in y, that is
(3x + x) + (2y - 2y) = (5 - 1)
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 in either of the 2 equations and solve for y
Substituting in (1)
3(1) + 2y = 5
3 + 2y = 5 ( subtract 3 from both sides )
2y = 2 ( divide both sides by 2 )
y = 1
Solution is (1, 1 )
