Answer:
60.72
Step-by-step explanation:
Monday: 60 degrees
Tuesday: temperature increases by 10 percent
60 + 10% of 60
60 + .10*60 = 70 +6 = 66
Wednesday: temperature decreases by 8 percent
66 - 8%of 66
66 - .08*66 = 66 -5.28=60.72
Answer:
The teachers have more combined siblings than the students.
Select 3 what?
Step-by-step explanation:
For this example all you have to do is subtract -4/5 from both side
So the answer is 51/5=x
Start by finding x. Look at the second parallel line; you have a straight line that is made up of a 90 degree angle, 2x, and x.
Since a straight line is 180 degrees, and you know a part of it is already 90 degrees, you can make 2x and x add up to 90 degrees.
2x + x = 90, combine like terms.
3x = 90, divide both sides by 3.
x = 30
Find y next. 2y and x are on opposite sides of the transversal and make a Z shape, so they must be alternate interior angles. The alternate interior angle theorem states that these types of angles are congruent.
We know what x is, 30 degrees, so make 2y and x equal to each other.
2y = 30, divide both sides by 2.
y = 15
Find z. Same thing as the bottom parallel line; 2y and z make up the straight line so they must add up to 180 degrees. We found y was 15, so multiply y by 2. y = 30, so make 30 + z add up to 180 degrees.
30 + z = 180, subtract 30 from both sides.
x = 150
