-3/4(8n+12)=3(n-3) show work pls

Nastasia [14]

Answer: n = 0

Step-by-step explanation:

Given expression

(-3/4) (8n + 12) = 3 (n - 3)

Expand parentheses and apply the distributive property

-6n - 9 = 3n - 9

Add 9 on both sides

-6n - 9 + 9 = 3n - 9 + 9

-6n = 3n

Subtract 3n on both sides

-6n - 3n = 3n - 3n

-9n = 0

Divide -9 on both sides

-9n / -9 = 0 / -9

$\boxed{n=0}$

Hope this helps!! :)

Find the measure of the angle HELP PLSSS URGENT!

Alecsey [184]

Answer:

It is 40 degrees

Step-by-step explanation:

The 2 lines, x and y are forming 90 degrees, and since we know that part of that complementary angle is 50 degrees, we would do:

50+x=90

-50 -50

-------------

x=40

Charles begins finding the volume of a trapezoidal prism using the formula A = One-half(b1 + b2)h to find the prism's base area.

yKpoI14uk [10]

Answer:

The expression that can be used to represent the volume of the trapezoidal prism is $(2x^3+6x^2)$

Step-by-step explanation:

step 1

Find the area of the trapezoidal base

The area of a trapezoid is given by the formula

$A=\frac{1}{2}(b_1+b_2)h$

we have

$b_1=(x+2)\ units\\b_2=(x+4)\\h=x$

substitute

$A=\frac{1}{2}(x+2+x+4)x$

$A=\frac{1}{2}(2x+6)x$

$A=(x+3)x\\A=(x^2+3x)\ units^2$

step 2

Find the volume of the trapezoidal prism

we know that

The volume of the prim is given by

$V=Bh$

where

B is the area of the base

H is the height of the prism

we have

$B=(x^2+3x)\ units^2$

$H=2x\ units$

substitute

$V=(x^2+3x)2x\\V=(2x^3+6x^2)\ units^3$

therefore

The expression that can be used to represent the volume of the trapezoidal prism is

$(2x^3+6x^2)$

Jalil is training for a marathon. On Monday, he biked 7.2 miles from his home to a park where he ran 10 laps on a path around a

GuDViN [60]

Answer:

.25 or 1/4 mile

Step-by-step explanation:

7.2 miles biking x 2 (round trip)= 14.4 miles

Total miles is 16.9-14.4= 2.5 miles left to run 10 times around a small pond. So to find out the distance of each lap around the pool you divide 2.5 miles by 10 laps equals .25 or 1/4 Mike is the distance around the pond.
