Answer:

both plumbers charge $120 for 3 hours of work

Step-by-step explanation:

1) x=3 and x stands for hours.

2) 120=y and y stands for money charged

Find the value of x. write your answer in simplest radical form
BartSMP [9]

Answer:

<h2>x = 4 \sqrt{2}</h2>

Step-by-step explanation:

To find the value of x we can use either sine or cosine

Using cosine we have

<h3>\cos(\theta)  =  \frac{adjacent}{hypotenuse}</h3>

From the question

x is the hypotenuse

4 is the adjacent

We have

<h3>\cos45=  \frac{4}{x}  \\ x \cos45 = 4 \\ x =  \frac{4}{ \cos(45) }</h3>

We have the final answer as

<h3>x = 4 \sqrt{2}</h3>

Hope this helps you

Sphinxa [80]
2x-14=-3x+6
You need to combine like terms and get all the x's on one side and the numbers on the other
2x+3x-14=6
5x=6+14
5x=20
now divide to get x alone
x=4

Hope that helps

A grocer wants to make a 10-pound mixture of cash tans peanuts that he can sell for $3.29 per pound. If cashews cost $5.60 per p
bagirrra123 [75]
Label each nut with a variable, c = cashews, p = peanuts.....
for a 10-pound mix, you will need c + p = 10
the price for 10-pounds would become 3.29 x 10 = 32.90 

You will need an unknown amount of cashews at 5.60/lb and an unknown amount of peanuts at 2.30/lbs to get your full 10 pounds valued at 32.90
5.60c + 2.30p = 32.90 

Now you 2 have a system of 2 equations and 2 unknowns
c + p = 105.6c + 2.3p = 32.9utilize substitution to solve:p = 10-c
5.6 c + 2.3 (10-c) = 32.9
solve for c then substitute back into c + p = 10 to solve for P

Hope this helps!
