A band marches in the African American Day Parade in New York City. The band marches 800 meters every 15 minutes. At this rate, how many kilometers does the
band march in 1 hour?

A marching band is a group of instrumental musicians who perform while marching, often for entertainment or competition. Instrumentation typically includes brass, woodwind, and percussion instruments. Most marching bands wear a uniform, often of a military-style, that includes an associated organization's colors, name or symbol. Most high school marching bands, and some college marching bands, are accompanied by a color guard, a group of performers who add a visual interpretation to the music through the use of props, most often flags, rifles, and sabres.

Marching bands are generally categorized by function, size, age, instrumentation, marching style, and type of show they perform. In addition to traditional parade performances, many marching bands also perform field shows at sporting events and marching band competitions. Increasingly, marching bands perform indoor concerts that implement many songs, traditions, and flair from outside performances. In some cases, at higher level competitions, bands will be placed into classes based on school size.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
