Since the temperature dropped 2 degrees every hour, and there are 6 hours, make a equation 2(6) in which 6 replaces the x. Just multiply and the total temperature change will have been 12 degrees.
Answer:
30
Step-by-step explanation:
62 = 2x+2
62-2 = 60
60/2 = 30
Answer:
B) x ≥ 3
Step-by-step explanation:
The circle is shaded which indicates that the inequality is equal to. The circle is on -3 and extends towards numbers that are greater than -3. Thus, all numbers are can be equal to or greater than -3.
Answer:
x = 21.5
Step-by-step explanation:
In the given trapezoid, the angles are consecutive interior angles.
i.e, consider the parallel sides of a trapezoid as parallel lines and the common side as the transversal. So, it is parallel lines cut by a transversal make a pair of consecutive interior angles which are supplementary.
i.e,
(5x + 13)° + (3x - 5)° =180°
5x + 13 + 3x - 5 = 180
8x + 8 = 180
8x = 180 - 8 =172
x= 172/8 = 21.5
So, 5x + 13 = 5(21.5) + 13 = 120.5°
3x - 5 = 3(21.5) -5 = 59.5°
6.8
= 6 + 0.8
= 6 + 8/10 (simplifying...)
= 6 + (8 : 2)/(10 : 2)
= 6 + 4/5
= 6 4/5 <----- this is the answer.
I hope this helps. =)
