Answer: 102 degrees
Step-by-step explanation:
This is an isosceles triangle because two of the sides are the same length which means that two angles are congruent as well.
180-(2(39))
=180-(78)
=102
X=-7y+34
x+7y=32
To begin with make the two problems the same kind of problem. By adding 7y on both sides for the first problem.
x+7y=34
x+7y=32
So the correct answer would be no solution because it's the same problem and it can't equal to different answers.
Answer: Last Option
Step-by-step explanation:
The initial height of the plant of species A is 25 cm and grows 3 centimeters per month.
If m represents the number of months elapsed then the equation for the height of the plant of species A is:
For species B the initial height is 10 cm and it grows 8 cm each month
If m represents the number of months elapsed then the equation for the height of the plant of species B is:
Finally, the system of equations is:
The answer is the last option
Answer:
x = -33
Step-by-step explanation:
Yes
No
Yes
No
This is because in order to be addition property of equality they have to add/ subtract by the same exact amount on both sides.
