Answer:
(C)26 units
Step-by-step explanation:
Since point B bisects AC into two equal parts
AB=BC
Since the two right triangles have side BD in common, we can then say that the two triangles are congruent and the length of the hypotenuses (AD and DC) are equal.
If AD=DC
8x-1=6x+9
8x-6x=9+1
2x=10
x=5
Now,
AB=3x-2
=3(5)-2
=13 Units
Since AB=BC
AC=AB+BC
=13+13
AC=26 units
The measure of AC is 26 units.
Answer:
12 dozen
Step-by-step explanation:
create a proportion of: dozen cookies / cups of pecan
let 'd' = dozen cookies
(3/1 ÷ 5/4) = (d ÷ 5)
simplify 3/1 ÷ 5/4 to be: 3/1 x 4/5, which equals 12/5
12/5 = d/5
cross-multiply to get:
5d = 60
d = 12
Answer:
She sells 14 dozen cookies
Step-by-step explanation:
You subtract 10 from the profit for her ingredients, and divide the answer of that by 4, for the 4 dollars.
C/a is the amount they bought so it would be 0.99*c or .99 times the amount they bought same goes to .79a
