Answer:
Valentina and Laura finished the same total number of shirts in 
hours.
Total number of shirts finished by Valentina 
Total number of shirts finished by Laura
Step-by-step explanation:
Suppose that Valentina and Laura finished the same total number of shirts in 
hours.
Valentina can embroider 2 shirts per hour and Valentina has already completed 15 shirts.
Total number of shirts finished by Valentina 
Laura can get through 3 shirts per hour and Laura has completed 11 shirts.
Total number of shirts finished by Laura 
Therefore,
So,
Valentina and Laura finished the same total number of shirts in hours.
Total number of shirts finished by Valentina 
Total number of shirts finished by Laura 
This is exponential decay which can be expressed as:
y=ab^t, y=final value, a=initial value, b=rate, t=time
In this case a=25000, r=(100-20)/100=0.8 so
y=25000(0.8^t), so in 4.5 years...
y=25000(0.8^4.5)
y≈$9158.93 (to nearest cent)
The value of m is 2450
<h3>What is Equation?</h3>
Two or more expressions with an Equal sign is called as Equation.
The given equation is
2(14m/400)=171.5
Distribute 2 with numerator on LHS
28m/400=171.5
14m/200=171.5
7m/100=171.5
Multiply 100 on both sides
7m=17150
m=2450
Hence, the value of m is 2450

Answer:
(3x - 2)(x - 5)
Step-by-step explanation:
3x² - 17a + 10
(3x - 2)(x - 5)
3x · x = 3x²
3x · -5 = -15x
-2 · x = -2x
-2 · -5 = 10
