Answer:
Since we know that ABCD is an isosceles trapezoid, we can also asume that its diagonals have the same length, which means:
AC = BD
=> 7x - 21 = 5x + 13
=> 7x - 5x = 21 + 13
=> 2x = 34
=> x = 34/2 = 17
So the answer is C.
This is exactly like the last question you posted. First you have to change the 3 and 2/3 mixed fraction into a pure fraction. 3 and 2/3 = 9/3 and 2/3 = 11/3 "eleven thirds." You now just need to divide (11 / 3) by (2/3.) (11 / 3) / (2 / 3) = (11 / 3) * (3 / 2) = 11 / 2 = 5 and 1/2 pieces. So if Mae cuts the ribbon into pieces that are 2/3 yard long, Mae will end up with 5 and 1/2 pieces. Checking our work, 5 pieces would be 5 * (2/3) = 10 / 3 = 3 and 1/3 yard long, leaving us with an extra 1/3 yard of ribbon, which is the "half piece" we got. Depending on the phrasing of the question, the answer could be "Mae makes 5 and a half pieces." or "Mae can make 5 pieces, and will have 1/3 yard of ribbon left over."
the answer is C. 9 1/3
Hope this helps!
Answer:
n= -12
Step-by-step explanation:
- 2n/3 + 7=15 Subtract 7 from both sides and move all terms containing
-7 = -7 n to the right
- 2n/3 = 8 multiply both sides of equation by - 3/2
-3/2 x (-2n/3) = -3/2 x 8
n= -3/2 x 8 cancel the common factor of 3
n= -12
