Answer: 43
Step-by-step explanation: 5x-27+10x-3= 180
combine like terms: 15x-30= 180
add 30 to both sides
15x=210 x=14
plug in 14 to (5x-27)
Answer:
The second ramp needs to have 25°.
Step-by-step explanation:
Required ramp angle for driving the car from the ground = 35°.
First ramp angle = 15°
Therefore, second ramp angle equals required ramp angle minus first ramp angle, which is = 35° - 15° = 20°
The 20° ramp angle will make the total ramp angle to be equal to 35°.
That is 15° + 20° = 35°
Answer:
x = (14,15,16,,,,,,n)
Step-by-step explanation:
Here,x belongs to set of natural number N
and Condition given for set is " x is greater than 13 "
Now, N=(1,2,3,4,5,6,,,,n) and given that x > 13.
thus, x = (14,15,16,,,,,,n)
D) a reflection in the line y = x
Answer:
P odd number, then 20) = 1 /14
Step-by-step explanation:
P( odd number) = number of odd numbers/ total
number of odd numbers = 3
total = 7
P( odd number) = 3/7
We keep the tile so that there are only 6 tiles left
P (20) = number of 20/ total
= 1/6
We multiply the probabilities together
P odd number, then 20) = 3/7 * 1/6 = 3/42 = 1 /14
