Answer:
3x - 124
Step-by-step explanation:
kindly find solutions in the picture above
We need to solve this system
<span>(3x + 2y = 36.50) *5
(2x + 5y = 50.00) *(-2)
15x+10y= 182.5
-4x -10y= -100
11x=82.5
x= 7.50 at the library
</span>2x + 5y = 50.00
<span>2*7.5+5y=50
15+5y=50
5y=35
y=7 at coffee cart
So,
correct answer is
</span><span>C.Percy earns a greater hourly wage of $7.50 at the library.</span><span>

<span>In </span>mathematics<span>, a </span>matrix<span> <span>(plural </span></span>matrices) is a
rectangular array of numbers, symbols, or expressions, arranged in rows and
columns.
Given that
E = [ 1 2]
<span>A = | 3
0|</span>
<span> | 2
-1 |</span>
<span>2EA = 2 [1 2] | 3 0|</span>
<span> | 2 -1 |</span>
<span>2EA = [ 14
-4]</span>

Answer:
-21-24/x
Step-by-step explanation:
f(x) is a function on his own which is f(x)=7x+8
we multiple it with another function which is g(x)=-1/x
that gives us (g*f)=-7-8/x
then multiple it by 3 we have -21-24x
