Answer:

(3x + 5)/2 = 7

Step-by-step explanation:

If you substitute 3 for x, you get the equation:

(3(3) + 5)/2 = 7

(9 + 5)/2 = 7

If the circumference of the circle above is 31.4 units, what is the area? (Use 3.14 for .) A. 62.8 units B. 78.5 units C. 985.96
jenyasd209 [6]

Answer:

78.5 units

Step-by-step explanation:

To find the area of a circle the formula is πr"2"

First we have to find the diameter the find the radius. We already know that the circumference is 31.4 what we have to do now is work backwards. ( 31.4 / 3.14=10) If the diameter of a circle is 10 the radius is 5. now we just have to follow  πr"2" to find the area of a circle. (5"2"= 25 x 3.14= 78.5 units)

What is an equivalent to -16m^2n-(-25m^2n)+(-7m^2n)
pantera1 [17]

Answer:

The equivalent expression is:

-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n

Step-by-step explanation:

Given the expression

-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a

=-16m^2n+25m^2n-7m^2n

\mathrm{Add\:similar\:elements:}\:-16m^2n+25m^2n-7m^2n=2m^2n

=2m^2n

Therefore, the equivalent expression is:

-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n
