Answer:
b = -2/4 or -0.5
Step-by-step explanation:
- 7 (2b - 4) = 5 (-2b + 6)
-14b + 28 = -10b + 30
-14b + 10b = 30 - 28
-4b = 2
-b = 2/4
b = -2/4
-2/4 = -0.5
Answer:
111 deg and 69 deg
Step-by-step explanation:
let the angles be x and y
given:
x - y = 42 degrees -------> eq 1
also given that they are supplemantry,
i.e x + y = 180 degrees ----------> eq 2
by elimination,
eq 1 + eq 2
(x-y) + (x+ y) = 42 + 180
2x = 222
x = 111 degrees (substitute back into eq 2)
111 + y = 180
y = 180 - 111
y = 69 deg
Answer:
<u><em>The original price would be 50$.</em></u>
Step-by-step explanation:
To find this answer you have to divide 25% by 100, which equals 0.25. Now multiply 0.25 by 40 and you get 10$. Since 10$ was the discount, you just add 10$ + 40$, therefore 50$ is the original price.
