4. 8 + 4 = 12
5. 7 + 5 = 12

Answer:

  (a) no

  (b) no

Step-by-step explanation:

The two questions are asking essentially the same thing. There is nothing that indicates DC ≅ DB or that AC ≅ AB. One (both) of these conditions is (are) required for ΔBAC to be isosceles, so that AD is both a perpendicular bisector of BC and a bisector of angle BAC.

There is not enough information to answer either question affirmatively.

The equation a = 640s gives the relationship between s square miles and a acres. Pam owns 7.5 square miles of farmland. How many
stich3 [128]
Quantity of farmland owned by Pam = 7.5 square miles.
The other important information given in the question is the equation relating square miles and acres. Using that information, the answer to the question can be easily reached.
a = 640s
   = 640 * 7.5 acres
   = 4800 acres.
From the above deduction, we can conclude that the correct option among all the options that are given in the question is the third option or option "C".

One third of a number reduced by 11 is equal to 4 more than the number
Alecsey [184]
1/3x -11 = 4+x is what we start with, then add 11 to both sides, then subtract x from both sides. Then when we divide both sides by -2/3, x will equal -22.5.
