Joseph is weaving a ceremonial Native American sash. The sash will be 8 feet long when it is completed.
Joseph wants to add a diamond shape every 0.4 feet along the sash.
How many diamonds will the sash have when it is completed?

20

Step-by-step explanation:

8 divided by 0.4=20, so twenty is the answer.

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
