Answer:
25%
Step-by-step explanation:
Apparently, we're to assume that anything not spent is saved.
Let Hideo's income be 1. Then Akira's income is 5/8. Akira's expenses are 60% = 3/5 of that value, so ...
Akira's expenses = (3/5)(5/8) = 3/8 . . . . . of Hideo's income
Hideo's expenses are twice this amount, so ...
Hideo's expenses = (2)(3/8) = 3/4 . . . . . of Hideo's income
That means Hideo saves 1 -3/4 = 1/4 = 25/100 = 25% of his income.
Hideo saves 25% of his income.
Answer: If it is 10.4 the answer would be 170.56 if it is 140 the answer would be 162,323.2, though I think it is<em><u> 170.56</u></em>

Answer:
f(x) = -2x -3
Step-by-step explanation:
-3 is the point in the y-axis, making it value b
the slope is 1/-2 making the value m = -2
Answer:
x = 12
Step-by-step explanation:
In a pair of intersecting lines the vertically opposite angles are equal.
(6x + 7)° = (8x - 17)°
6x + 7 = 8x - 17
Subtract 8x + 7 from both sides:
6x + 7 - (8x + 7) = 8x - 17 - (8x + 7)
(6x - 8x) + (7 - 7) = (8x - 8x) + (-17 - 7)
6x - 8x = -2x:
-2x + (7 - 7) = (8x - 8x) + (-17 - 7)
7 - 7 = 0:
-2x = (8x - 8x) + (-17 - 7)
8x - 8x = 0:
-2x = -17 - 7
-17 - 7 = -24:
-2x = -24
Divide both sides by -2:
x = 12
