Answer: True
Step-by-Step Explanation:
=> 2x + 3y = -7 (Eq. 1)
=> -x = 2y (Eq. 2)
=> x = 1, y = -3
Substitute values of ‘x’ and ‘y’ in Eq. 1 :-
=> 2x + 3y = -7
= 2(1) + 3(-3) = -7
= 2 + -9 = -7
=> -7 = -7
=> LHS = RHS
Therefore, it is a Solution.
Answer:
the answer is A because it is ap
You take the 4 and bring it to the power of 7
Answer:
4,200 is the exact same is 42 so 42x4 would be your answer to work that out you would need to half and half until you know what x table you need
Step-by-step explanation:
Answer:?
This is the perfect place to use a proportion:
Old capacity . . . 50 gallons
Old distance . . . 425 miles
New capacity . . . (50 + 30) = 80 gallons
New distance . . . D
The proportion:
425 / 50 = D / 80 .
Multiply each side by 80 : 425 x 80 / 50 = D
680 = D .
