The equation p= 2.5m + 35 represents the price p of a bracelet, where m is the cost of the materials. The price of a bracelet is
Klio2033 [76]
P= 2.5m + 35    (replace p with 115)
115= 2.5m + 35  (subract 35 from each side)
115 - 35 = 2.5m
80 = 2.5m    (divide 2.5 from each side)
80/2.5= 2.5m/2.5
32 = m

The price of the materials is $32

What is the product of 7/16 and -6/13 I will make you the brainlest
mr_godi [17]

Answer:

\frac{7}{16} *\frac{-6}{13} = \frac{-42}{208}

Step-by-step explanation:

\frac{7}{16} *\frac{-6}{13} = \frac{-42}{208} . First multiply 7*-6=-42.

Then do 16*13=208.

Simplify by dividing both by 2.

You get \frac{-42}{208}=\frac{-21}{104}.

Your final simplified answer is \frac{-21}{104}

I hope this helps!
