Two solutions were found :

w = 1

w = -4

Step-by-step explanation:

w =(-3+√25)/2=(-3+5)/2= 1.000

or:

w =(-3-√25)/2=(-3-5)/2= -4.000

Just 6, 8, and 10 plz<br> thx
marshall27 [118]
6 - 15/40 = 0.375 = 37.5%
When looking to convert a decimal to a percent you move the decimal over two places so, 0.375 becomes 37.5 

8 - 70*1.2 = 80 

You see 100% is equal to 1.00 when multiplying/dividing. So 1.2 = 120%

10 - 48*0.25 = 12 and 12+48 = 60 So, 60.

Here, we use 0.25 because 100% - 75% = 25% or... 1.0 - 0.75 = 0.25

If x varies directly with y and y is 10 when x is 8, what is x when y is 18?
swat32
Knowing that x varies directly with y, we know the basic skeleton of the equation is y = mx. 

To find m, plug in the known coordinate (8,10), where the x-coordinate is 8 and the y-coordinate is 10.
y=mx \\ 10=m8 \\ (10)/8=(8m)/8 \\ m= \frac{10}{8} = \frac{5}{4}

Then, plug in m to the equation to get y = (5/4)x.

Finally, plug in the y-coordinate 18 to the equation and solve for x!
y= \frac{5}{4}x \\ 18= \frac{5}{4}x \\  \frac{4}{5}(18)=( \frac{5}{4}x) \frac{4}{5} \\ x= \frac{4*18}{5}  \\  x= \frac{72}{5}

Your exact answer is x = 72/5. However, if your teacher prefers decimals, then x = 14.4

Hope this helps!
