Answer:
x = 1
Step-by-step explanation:
Given
5(2x - 8) + 15 = - 15 ( subtract 15 from both sides )
5(2x - 8) = - 30 ( divide both sides by 5 )
2x - 8 = - 6 ( add 8 to both sides )
2x = 2 ( divide both sides by 2 )
x = 1

Answer:
c. 2,320miles
Step-by-step explanation:
29 divided by 1/4 = 116
116*20=2,320
We divide 60 by 2 as many times as possible to get 60 = 15 x 2 x 2. 2 is a prime number so we don't need to break the 2's down any more. Instead we break 15 down. 15 doesn't divide by 2 so we try the next prime number: 3 Divide 15 by 3 to get 15 = 5 x 3, and so 60 = 5 x 3 x 2 x 2.
Answer:
x = 13
39° and 51°
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
This is a right angle triangle, so one side has a size of 90 degrees.
3x + 4x - 1 + 90 = 180
7x + 89 = 180
7x = 91
x = 91/7
x = 13
Put x as 13 to work out the size of the angles.
3(13) = 39
4(13) - 1
52 - 1 = 51
