What is 1/8y+17+2y-118 please
lisabon 2012 [21]

Answer:

(17y/8) - 101 or (17y - 808) / 8

Step-by-step explanation:

Please enclose the fractional coefficient 1/8 inside paretheses:

(1/8)y + 17 + 2y - 118.

Now combine like terms.  (1/8)y + 2y comes to (1/8)y + 16y/8 = (17/8)y.

We thus have (17/8)y + 17 - 118.  Leaving (17/8)y alone, evaluate 17 - 118:

(17y/8) - 101

You could leave your answer in this form, or combine the terms using the LCD 8:

17y - 808

alexgriva [62]

Answer:

  • x = - 3 or x = 2

Step-by-step explanation:

Solve the quadratic equation by factorizasion

  • x² + x - 6 = 0
  • x² - 2x + 3x - 6 = 0
  • x(x - 2) + 3(x - 2) = 0
  • (x + 3)(x - 2) = 0
  • x + 3 = 0 or x - 2 = 0
  • x = - 3 or x = 2

<u>Question 11</u>

1) \overline{BA} \cong \overline{FA}, \angle 1 \cong \angle 2 (given)

2) \angle A \cong \angle A (reflexive property)

3) \triangle AEB \cong \triangle ACF (ASA)

4) \overline{AC} \cong \overline{AE} (CPCTC)

<u>Question 12</u>

1) Isosceles \triangle ACD with \overline{AC} \cong \overline{AD}, \overline{BC} \cong \overline{ED} (given)

2) \angle ACD \cong \angle ADC (angles opposite congruent sides in a triangle are congruent)

3) \angle ACB and \angle ACD are supplementary. \angle ADC and \angle ADE are supplementary (angles that form a linear pair are supplementary)

4) \angle ACB \cong \angle ADE (supplements of congruent angles are congruent)

5) \triangle ABC \cong \triangle AED (SAS)

6) \overline{AB} \cong \overline{AE} (CPCTC)

7) \triangle ABE is an isosceles triangle (a triangle with two congruent sides is isosceles)

<em>Note: I changed the names of the segments in Question 11 because of the word filter.</em>
