1. Unit rate= 720:60 and if you want it simplified then it will be 12:1
2. Answer is A= 21/7= 3/1
8 - 2x + 12x - 3
8 + (-2x + 12x) - 3
8 + 10x - 3
8-3 + 10x
5 + 10x
10x +5
Let's find out the cost of labor shall we...
$8 x 40 x 2 = $640
--------
Now let's answer your question...
($640)/($2000) = 0.32
---------
This means that the cost of labor would be equal to 32% of the revenue as 0.32 = 32/100.
Answer:
a)
b)
c)
Explanation -
a) 2/3 p + 10 = r
Value of r = 22 (given)
2/3 p + 10 = 22
2/3 p = 22- 10
2/3 p = 12
p = 12 × 3 /2
p = 6 × 3
<em><u>p</u></em><em><u>=</u></em><em><u>1</u></em><em><u>8</u></em><em><u> </u></em>
b) (-17) + 5k = t
value of k = 4 (given)
(-17) +5 (4) = t
(-17) + 20 = t
<em><u>3</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>t</u></em><em><u> </u></em>
c) 0 = 5p - 3b
b= 2 (given)
0 = 5p - 3(2)
0 = 5p - 6
6 = 5p
<em><u>6</u></em><em><u>/</u></em><em><u>5</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>p</u></em>
