Answer:

Step-by-step explanation:

105/120= 0.875

In order to obtain a percentage, you move the decimal point to the right two spaces.

Therefore, 0.0875 will be 87.5%

What this tells you is that 87.5% of the wire was used.

So, 100%-87.5%= 12.5% of wire was left over/unused.

A line with a slope of -2 is written in the form y=mx+b.

yanalaym [24]

Answer:

b = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Here m = - 2 , then

y = - 2x + b ← is the partial equation

To find b substitute (5, - 7 ) into the partial equation

- 7 = - 10 + b ⇒ b = - 7 + 10 = 3
