Answer:
x=25
Step-by-step explanation:
x+y=100 (y being number of 8¢ stamps)
12x+ 8y = 900
-----------------------------------
y = 100-x
12x + 8y = 900
----------------------------------------
12x + 8(100-x) = 900
12x + 800 - 8x = 900
12x - 8x = 900 - 800
4x = 100
x=25
It’s (5/3)x +3 in slope intercept form
Explain
1 - 4n +1 +3n
(combine like terms)
2-n
(Subtract 2 to other side)
2-n=0
-2. -2
-2=-n
(Divide by negative 1)
-2/1=n/-1
N=1
It is 52. Here is why...
<span>5 + 6 x 3 + (7 - 3) x (16 divided by 2) - 3
</span>= 5+18+4 <span>x 8-3
=5+18+ 32-3
=23+32-3
=55-3
=52
