I always find that decimals are easier to work with so 5/8 as a decimal is 0.625. So 0.625 compared to 0.58 is bigger, so 5/8 is bigger than 0.58.
15% = 0.15 and 1/5 = 0.2 So 1/5 is bigger than 15%
Answer:
Step-by-step explanation:
x² + 4x -21 = x² + 7x - 3x -3*7
= x*(x + 7) -3(x + 7)
=(x + 7)*(x-3)
(a) 8(4x+3) > -1 + 7x
32x + 24 > -1 + 7x
32x - 7x > -1 -25
25x >-26
x > -26/25
(b) 167 < 6 + 7(2 - 7r)
167 < 6 + 14 - 49r
49r < 6 + 14 - 167
49r < - 147
r < - 3
(c) 8x + 40 > -8 ( 1 - 7x)
8x + 40 > -8 + 56x
56x - 8x < 48
48x < 48
x < 1
(d)5( 6 + 3r) + 7 > 127
30 + 15r + 7 > 127
15r > 127 - 37
15r > 90
r > 6
6.25 * 4 = $25
25 + 6.25 is 31.25
31.25 plus 8.25 = 37.50
ANSWER : $37.50
