MARK AS BRAINLIEST PLZZZ
Answer:
Son + Daughter 60%
Son - 23,625
Daughter - 16,875
Wife % - 40%
Total - 67,500
Step-by-step explanation:
1. We do 35 + 25 to get 60
2. 27000 / 40 to get 1% = 625
Then, 625 x 35 = 23,625
3. 625 x 25 = 16,875
4. 100 - 60 ( kids ) = 40%
5. 40500 ( kids ) + 27000 = 67, 500
A. 3x + y = 13 → 15x + 5y = 65
x - 5y = 15 → x - 5y = 15
16x = 80
16 16
x = 5
x - 5y = 15
5 - 5y = 15
- 5 - 5
-5y = 10
-5 -5
y = -2
(x, y) = (5, -2)
b. 6x - y = 14
2x + y = 12
8x = 26
8 8
x = 3¹/₄
6x - y = 14
6(3¹/₄) - y = 14
19¹/₂ - y = 14
- 19¹/₂ - 19¹/₂
-y = -5¹/₂
-1 -1
y = 5¹/₂
(x, y) = (3¹/₄, 5¹/₂)
c. 3x - 4y = 22 → 15x - 20y = 110
2x + 5y = 7 → 8x + 20y = 28
23x = 138
23 23
x = 6
3x - 4y = 22
3(6) - 4y = 22
18 - 4y = 22
- 18 - 18
-4y = 4
-4 -4
y = -1
(x, y) = (6, -1)
The sum should be answer choice A.
Hope this helps you out!
