Answer:
y = 3
Step-by-step explanation:
Here the value of x is -1 . So putting the value of x in the eqn. gives :-
(anything multiplied with 0 gives the product as 0)
Answer:
use table B
Step-by-step explanation:
the perimeter of table A =
2×(96+42) = 2× 138 = 276 inches
the perimeter of table B =
2×3.14×45 = 282.6 inches
table B > table A
8 inches=2/3 feet.
(2/3)÷3=2/9
1.5÷3=1/2
1÷1/2=2
(2/9)×2=4/9
The answer is 4/9 feet
Answer:
B, D, E
Step-by-step explanation:
-8x - 6y = 10
x + 7y = 9
You can multiply any of these equations by a constant without changing the solution.
B. 4x + 3y = -10 is equivalent to multiplying each side of the first equation by -½.
D. -16x - 12y = 20 is equivalent to multiplying each side of the first equation by 2.
E. 3x + 21y = 27 is equivalent to multiplying each side of the second equation by 3.
A. -2x + 7y = 9 is wrong. The signs don't match those of the second equation.
C. 24x + 18y = 10 is wrong. The signs don't match those of the first equation.
F. x - 14y = -18 is wrong. The coefficient of x should be -2.
The answer to the problem is 25
