Answer:
x = 1/3
Step-by-step explanation:
-4(3x − 2) = 6x + 2
Distribute
-12x +8 = 6x +2
Add 12x to each side
12x-12x+8 = 6x+2+12x
8 = 18x+2
Subtract 2 from each side
8-2 = 18x+2-2
6 = 18x
Divide each side by 18
6/18 = 18x/18
1/3 =x
In quadrant 2, 
and 
. Use the Pythagorean identity to establish that
Then
Answer:
3
3 x 6 = 18
3 x 7 = 21
You can also find the answer by knowing that the only number 21 is divisible by is 7 and 3
Step-by-step explanation:
The second choice
7+ -13= -6
Answer - 42 Sandwiches
Explanation -
56 is what you start out with. you will need to find 25% of those 56 to see the remaining. So 25% of 56 is 14 because .25 x 56 is 14. You then subtract 56 from the 14 Tuna sandwiches and you’re left with 42.
