What is .65% of 160? Show your work
vladimir2022 [97]
0.65/100 = x/160 Ok, until now?

You then find the cross product: (0.65)(160) = 100x

104 = 100x        104/100 = 1.04

So x = 1.04 and it is also 0.65% of 160


Hope this helps!

Write the Equation of the line in slope intercept form<br> (0, -3), (7.5,0)
makkiz [27]

Answer:

Step-by-step explanation:

First, start off by solving for the slope using this formula:

\frac{y_{2} -y_{1} }{x_{2}-x_{1}  }

Then, plug in the values: \frac{0-(-3)}{7.5-0}

Solve the equation: \frac{3}{7.5}

That's your slope.

Then plug in one of the coordinates given in the problem for x and y and solve this equation:

y=\frac{3}{7.5}x+b

Hope that helped!!! :)
