Answer the following questions.
kakasveta [241]

Answer:

x=83

Step-by-step explanation:

The sum of interior angles in a triangle will always be equal to 180 degrees. Knowing this, we can set up the following equation:

35+62+x=180

97+x=180

Subtract both sides by 97

97+x-97=180-97

x=83

I hope this helps!

What is the value of this expression when d = 4 7/8 and f = 3 1/2<br> 6 (d - f) + f
natima [27]

The value of the expression 6 (d - f) + f when d = 4 7/8  and f = 3 1/2 is 47/4 or 11\frac{3}{4} .

<h3>How to Solve Algebra expression?</h3>

6 (d - f) + f

when d = 4 7/8 and f = 3 1/2

Given the data in the question;

  • d = 4 7/8 =
  • f = 3 1/2 =
  • What is 6 (d - f) + f = ?

First, we convert the mixed fraction into an improper fraction

d = 4 7/8 = ( 8×4 + 7 )/8 = 39/8

f = 3 1/2 = ( 2×3 + 1 )/8 = 7/2

Now, we substitute the values of d and f into the expression.

234/8 - 42/2 + 7/2

234/8 - 168/8 + 7/2

33/4 + 7/2

33/4 + 14/4

47/4 or 11\frac{3}{4}

Therefore, the value of the expression 6 (d - f) + f when d = 4 7/8  and f = 3 1/2 is 47/4 or 11\frac{3}{4} .
