Lets write this out:-

\frac{50}{100} + \frac{30}{100}

To answer this we just need to add the numerators of both fractions because the denominator's are already common multiples. 

\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}

Now lets simplify \frac{80}{100}.

\frac{80/20}{100/20}=  \frac{4}{5}

So, \frac{50}{100}+  \frac{30}{100} = \frac{80}{100}= \frac{4}{5}

Hope I helped ya!! xD

\frac{50}{100} + [tex] \frac{30}{100}[\tex]. Just multiply the numerators. The denominator is already a common denominator.

-4 2/3= 2n/3 + 1/3 + n/3 <br> solve for n<br> multi step equation
Serggg [28]

Answer:

n=−43/3

Step-by-step explanation:

−42/3=2n/3+1/3+n/3

−14=2/3n+1/3+1/3n

−14=(2/3n+1/3n)+(1/3)

−14=n+1/3

Flip the equation.

n+1/3=−14

Subtract 1/3 from both sides.

n+1/3−1/3=−14−1/3

n=−43/3

Evaluate the expression. 42 + 5 • 32 – 42 ÷ 23
Leto [7]
42 + 5 * 32 - 42 ÷ 23

I am going to use the PEMDAS order. Parenthesis, Exponents, Multiply, Divide, Add, Subtract

Multiply ⇒ 5 * 32 = 160
42 + 160 - 42 ÷ 23

Divide ⇒ - 42 / 23 = -1.83
42 + 160 - 1.83

Add ⇒ 42 + 160 = 202
202 - 1.83

Subtract ⇒ 202 - 1.83 = 200.17

42 + 5 * 32 - 42 ÷ 23 = 200.17

A farmer creates a rectangular pen using part of the wall of a barn for one side of the pen and a total of 130 feet of fencing f
Nat2105 [25]

The equation that describes the which gives the area of the pen, A, as a function of x, the length of fence parallel to the barn is A = 130x - x²

<h3>How to find area of a rectangle?</h3>

The pen is rectangular. Therefore,

area of a rectangle = lw

where

  • l = length
  • w = width

Therefore,

perimeter = 2w + l

perimeter = 2w + x

130 = 2w + x

130 - x = 2w

w = 65 - 1/ 2 x

A = xw

A = x(65 - 1/ 2 x)

A = 65x - 1 / 2 x²

Therefore, the function that represents A, the area of the pen is as follows:

A = 130x - x²
