Answer:
Only:
B. x=7
D. x=0
Step-by-step explanation:
Substitute the answers in the formula and only 7 and 0 will work.
Answer:
w= 6
Step-by-step explanation:
I just started by making an educated guess using the values already given. Then I inserted that into the problem to see if it worked.
L= 2w - 5
I used 6 as a random, educated guess for the value of w.
L = 2(6) - 5
L = 12-5
L = 7
Then, multiply L by 2 to account for both side lengths of the rectangle.
7(2)= 14
Subtract that value from the total perimeter to find what the width must equal.
26 - 14 = 12
Divide that answer by 2 since there are two sides for width.
12/2 = 6
I know this was kind of long, but I hope it helps! :)
Answer: B
<u>Step-by-step explanation:</u>
2x - 3y = -7 → 2(2x - 3y = -7) → 4x - 6y = -14
-4x + 6y = -10 → 1(-4x + 6y = -10) → <u>-4x + 6y</u> = <u>-10 </u>
0 = -24
FALSE
Since this makes a false statement, there are no solutions
