One number is three less than two times another number. If the sum of the numbers is 15, find the numbers
1 answer:
9514 1404 393
Answer:
6, 9
Step-by-step explanation:
Let x represent one of the numbers. Then the other number is 15-x (because their sum is 15). The relation between the numbers is ...
2x -3 = 15 -x . . . . . three less than twice one number is the other number
3x = 18 . . . . . . add 3+x
x = 6 . . . . . . divide by 3
15-x = 9 . . . . find the other number
The two numbers are 6 and 9.

Answer:
53.04
Step-by-step explanation:
The length can be found using the Pythagorean Theorem...
c^2=a^2+b^2 and in this case:
d^2=(dx^2)+(dy^2)
d^2=(3-7)^2+(12-9)^2
d^2=-4^2+3^2
d^2=16+9
d^2=25
d=5
So the length of AB=5 units.
Perimeter=|1+|2+|3
=12.5+10.6+9.5=32.6inches
Answer is A (-5 , 1)
Coordinate point (-5 , 1) lies in the shaded region
