You want to find values of v (number of visors sold) and c (number of caps sold) that satisfy the equation

... 3v + 7c = 4480

In intercept form, this equation is

... v/(1493 1/3) + c/640 = 1 . . . . . divide by 4480

Among other things, this tells us one solution is

... (v, c) = (0, 640)

The least common multiple of 3 and 7 is 21, so decreasing the number of caps sold by some multiple of 3 and increasing the number of visors sold by that same multiple of 7 will result in another possible solution.

The largest multiple of 21 that is less than 4480 is 213. Another possible solution is (0 +213·7, 640 -213·3) = (1491, 1)

We can also pick some number in between, say using 100 as the multiple

... (0 +100·7, 640 -100·3) = (700, 340)

In summary, your three solutions could be

... (visors, caps) = (0, 640), (700, 340), (1491, 1)

Monica has 7.68 meters of gold wire she wants to cut into 0.96 meter log pieces. She also has 7.45 meters if silver wire she wan
Murrr4er [49]

Answer:

Monica has 3 more pieces of gold than silver after she cut all her wire

Step-by-step explanation:

Total length of gold wire Monica has= 7.68 meters

Length of each piece Monica wants to cut the wire into = 0.96 meters

Total number of pieces she can cut  = \frac{Length\ of\ wire}{length\ of \ piece}= \frac{7.68}{0.96} = 8 pieces of gold wire

Total length of gold wire Monica has = 7.45 meters

Length of each piece Monica wants to cut the wire into = 1.49 meters

Total number of pieces she can cut  = \frac{Length\ of\ wire}{length\ of \ piece}= \frac{7.45}{1.49} =5 pieces silver wire

Gold wire pieces= 8

Silver wire pieces= 5

Difference in the number of pieces = 8-5=3

Monica has 3 more pieces of gold than silver after she cut all her wire

Classify the expression 7x3 as a monomial, binomial, trinomial, or polynomial
saul85 [17]
Hey Savion24, 

A monomial can be defined as a number (1,2,3,4), a variable (x,y,z), or the product of numbers and variables (4x). 

A binomial is a polynomial with two terms.

A trinomial is a polynomial with three terms.  

              Now lets have a look at the expression 7x³. 

The given expression is a monomial as it is the product of a number and variable. 

→ Hope this helps,
