Answer:
1st option
Step-by-step explanation:
The 2 angles are alternate exterior angles and are congruent , so
3x = 2x + 20 ( subtract 2x from both sides )
x = 20
Strictly speacking, since 'c' is defined in the statement this shoudl work:
Part 1) According to the exercise, the letter 'c' represents the total cost of the three pounds of oranges. So c is the total cost of the three pounds of oranges.
Part 2) Rami has three pounds of oranges. In order to know how much a pound of oranges cost, he will have to divide by 3 the total cost of the three pounds 'c'
Part 3) The cost per pound is:
cost 1 pound of oranges = c/3
To do this, multiply each of the four elements in matrix D by -1/2 or -0.5:
| 9 8 |
| -7 -4 |
Move the decimal 2 times to the right, so 20%
