Answer:
Its C
Step-by-step explanation:
You can use a calculator or you could change the percent to a fraction. 20% is equivalent to 20/100.
So just multiply 150 by 20 and divide that answer by 100 to get a number of 30 CDs of boy bands
<h3>The equation, when solved for x, gives the amount of money Jim earned last week is: 700 = 4x - 20</h3>
<em><u>Solution:</u></em>
Given that,
Jim earned $700 this week
This was $20 less than four times the amount he earned last week
To find: amount of money Jim earned last week
Let "x" be the amount of money Jim earned last week
From given,
Jim earnings this week = $20 less than four times the amount he earned last week
Therefore,
700 = 4x - 20
Thus the equation is found
a^2 + b^2 = c^2
a = sqrt(c^2 - b^2) = sqrt (20^2 - 16^2)
= 12
sin
= a/c = 12/20
= 3/5
cos
= b/c = 16/20
= 4/5
tan
= a/b = 12/16
= 3/4
csc
= c/a = 20/12
= 5/3
= 1 2/3
sec
= c/b = 20/16
= 5/4
= 1 1/4
Answer:
+2
Step-by-step explanation:
-(-2)
since: same signs gives the positive sign i.e + and different signs gives negative sign -
-×-2
=+2
