If you multiply the top equation by -2 you get:
-4x -14y = 14 => -4x = 14+14y
now you can plug in the -4x into the second equation:
14+14y - 3y = -19 => 11y = -33 => y=-3
Fill in y=-3 in either equation to find x:
2x - 21 = -7 => 2x = 14 => x=7
So your ordered pair is (7,-3)
STEP 1:
BAGS OF FOUR
find number of bags needed to total 74 apples
= 74 ÷ 4 apples/bag
= 18.5 bags
*must round up to 19 bags because we cannot buy a partial bag
STEP 2:
BAGS OF FOUR
calculate price of 19 bags of 4 apples per bag
= 19 bags * $5/bag
= $95 for 19 bags of 4 apples/bag
STEP 3:
BAGS OF SIX
find number of bags needed to total 74 apples
= 74 ÷ 6 apples per bag
= 12.3333 bags needed
*must round up to 13 bags because we cannot buy a partial bag
STEP 4:
BAGS OF SIX
calculate price of 13 bags of 6 apples per bag
= 13 bags * $7 per bag
= $91 for 13 bags of 6 apples/bag
ANSWER: The smallest cost to buy 74 apples is $91.
Hope this helps! :)
Answer:
1 and 2 they both are x=0
Step-by-step explanation:
Answer: (x - 4) • (3x + 2)
Step-by-step explanation:
Answer:
is the solution to the equation: 
The statement is true.
Option A is correct.
Step-by-step explanation:
We need to determine if 
is the solution to the equation:
Solving the equation first to find value of x
Combining like terms:
Subtracting 2x on both sides
Now, subtracting 12 on both sides
Divide both sides by -6
So, we get
Therefore we can say that is the solution to the equation:
The statement is true.
Option A is correct.
