Answer:

18 and 11/16

Step-by-step explanation:

I converted the two numbers into improper fractions which leaves me with

71/8+157/16

I thenn made sure I had common denominators, which means I need to multiply the first number by 2/2 and I'm left with:

142/16+157/16

I can now add the 2 numbers together and I get:

299/16

now we just need to convert the number into a mixed number by dividing, and I am left with:

18 and 11/16

I really need someone to answer this, QUICK!
Elodia [21]

Answer:

A. LCM=72   B. GCF=7    C. 7(5+9)

Step-by-step explanation:

A. 8/2=4/2=2  9/3=3   Use the denominators to find the LCM. In this case, the LCM is 72.

B.  35/5=7   63/3=21/3=7    The GCF for these numbers is 7 because it is the only factor that they have in common.

C.   7 x 14=88     Since 5 and 9 don't have common factors, they work perfectly for this problem.

The projected sales volume of a video game cartridge is given by the function s(p) = 3000 / (2p + a), where s is the number of c
Alex_Xolod [135]

Answer: 149 cartridges will be sold at 20 dollars per cartridge.

Step-by-step explanation:

Given: The projected sales volume of a video game cartridge is given by the function s(p)=\dfrac{3000}{2p+a}, where <em>s</em> is the number of cartridges sold, in thousands; <em>p</em> is the price per cartridge, in dollars; and <em>a</em> is a constant.

Put s(p)=100000, p= 10, we get

100000=\dfrac{3000}{2(10)+a}\\\\\Rightarrow\ 100=\dfrac{3}{20+a}\\\\\Rightarrow\ 100(20+a)=3\\\\\Rightarrow\ 2000+100a=3\\\\\Rightarrow\ 100a=-1997\\\\\Rightarrow\ a=-19.97

i.e. s(p)=\dfrac{3000}{2p-19.97}

Put p=20, we get

s(20)=\dfrac{3000}{2(20)-19.97}\\\\=\dfrac{3000}{40-19.97}\\\\=\dfrac{3000}{20.03}\approx149

Hence, 149 cartridges will be sold at 20 dollars per cartridge.
