Answer:

x=14

Step-by-step explanation:

2 times x = 2x and 2 time 9 is 18 so the equation is 2x-18=10. then you add 18 to both sides and get 2x=28 then simplify to x=14

Answer:

x=14

Step-by-step explanation:

2(x-9)=10

Step one - Simplify both sides

(2)(x)+(2)(-9)=10 (distribute)

2x+-18=10

2x-18=10

Step two - Add 18 to both sides

2x-18+18=10+18

2x=28

Step three - Divide both sides by 2

2x÷2 = 28÷2

x= 14

Answer:

x=14

If 3 dogs are going to share 32 ounces of canned dog food equally by weight how many ounces should each dog get? I NEED THIS ASA

mr_godi [17]

Maybe I'm not understanding, but I would say 32 ounces divided by 3 gives an equal amount of food for each dog. So i would just solve 32/3. Hope this helps... sorry if it didn't!

Movies are on sale for 3/4 the original price. If the original price is $10, what is the sale price?

baherus [9]

$\frac{3}{4}\ of\ the\ original\ price=\frac{3}{4}\times\$10=\left(\frac{3}{4}\times\frac{10}{1}\right)\$=\frac{3\times10}{4\times1}\$\\\\=\frac{30}{4}\$=\frac{28+2}{4}\$=\boxed{\boxed{7\frac{2}{4}\$=7\frac{1}{2}\$=\boxed{\$7.50}}}$
