Answer:

Step-by-step explanation:
Because the initial temperature is 40 degrees and it increases by 10, add the two values together to get the final temperature.
40 + 10 = 50
Therefore, the final answer is 50 degrees.
ABC is an isosceles triangle.
Sides : AB = BC
3 x - 7 = 2x
3 x - 2 x - 7 = 2 x - 2 x
x - 7 = 0
x - 7 + 7 = 0 + 7
x = 7
Segment AC:
AC = 3 * 7 - 7 = 21 - 7 = 14
Answer: C ) 14
Answer:

Step-by-step explanation:
since we know that Vicky's pay increases each year by 5% and we know how many years, we can just times that 5% by three and make it 15% From there, you just add 7.15 to .15 and you get your answer!
Answer:
60° : 75° : 120° : 105°
Step-by-step explanation:
I like to work these by considering the relationship between a "ratio unit" and the angle it represents. Here, the sum of ratio units is 4+5+8+7 = 24. The sum of angles in a quadrilateral is 360°, so each ratio unit must stand for ...
360°/24 = 15°
Multiplying the ratio units by this value, we find the angles to be ...
(4 : 5 : 8 : 7) × 15° = 60° : 75° : 120° : 105°
