Answer attached
Step-by-step explanation:
First step is to turn 5% into a decimal -- 0.05
Next, find out what 5% of $32.55 is by multiplying
0.05 x 32.55
= 1.6275
Round to the nearest cent
= $1.63
This is the amount of tax $32.55
If we want to know what it the book costs before tax we simply take the tax off.
$32.55 - $1.63
= $30.92
Answer:
x = 7
Step-by-step explanation:
4x + 5 = x + 26
4x - x = 26 - 5
3x = 21
x = 21/3
x = 7
Check:
4*7 + 5 = 7 + 26
28 + 5 = 33
Answer:
(-4,5)
*View attached graph*
Step-by-step explanation:
y = -2x - 3
4y + x = 16
4y + x = 16
4(-2x - 3) + x = 16
-8x - 12 + x = 16
-7x - 12 = 16
+12 + 12
-7x = 28
/-7 /-7
x = -4
4y + x = 16
4y + (-4) = 16
4y - 4 = 16
+ 4 + 4
4y = 20
/4 /4
y = 5
(x,y) -> (-4,5)
Hope this helps!
