Answer:
I think he will have 6,56$
Let 11x + 15y + 23 = 0 be equation (1)
And 7x - 2y - 20 = 0 be equation (2)
Multiply equation (1) by 2:
22x + 30y + 46 = 0
Multiply equation (2) by 15:
105x - 30y - 300 = 0
Add equations (1) and (2):
22x + 105x + 30y - 30y + 46 - 300 = 0
127x - 254 = 0
127x = 254
x = 254/127
[x = 2]
Substitute x = 2 in equation (1) to find y:
11(2) + 15y + 23 = 0
22 + 15y + 23 = 0
15y + 45 = 0
15y = -45
y = -45/15
y = -3
Therefore, x = 2 and y = -3.
Rabbit: y=5x-7
Turtle: y=x
use substitution
x=5x-7
-4x=-7
x=7/4=1.75

Answer:
w = 34°
Step-by-step explanation:
Every quadrilateral is equal to 360 degrees. If you know 3 out of the 4 angles, then what you need to do is add up each angle and subtract the sum from 360 to find the remaining angle.
90 + 90 + 146 = 326
360 - 326 = 34
w = 34
