Answer:

x = 6

Step-by-step explanation:

5 (x - 3) + 2 = 5 (2x - 8) - 3

<em>remove the parenteses</em>

5x - 15 + 2 = 10x - 40 - 3

<h3><em>calculate</em></h3>

5x - 13 = 10x - 43

<h3><em>move the terms</em></h3>

5x - 10x = -43 + 13

<h3><em>collect like terms </em></h3><h3><em>calculate</em></h3>

-5x = -30

<h3><em>divide both sides</em></h3><h3><em /></h3>

Solution

x = 6

Answer:

$318.17, out of state college is $161.12 cheaper per month

Step-by-step explanation:

72*24 = 1728 + 410*4 = 1728 + 1640 = 3368 + 450 = 18/12 = $318.17

8700+650*9 = 8700 + 5850 = 14550/9 = 1616.66

8500+400*9 = 8500 + 3600 = 12100 + 1000 = 13100/9 = 1455.56

1616.67 - 1455.56= $161.11 (use $161.12)

What is -1 OVER 7 Multiplyed by 1 over 5

ycow [4]

-1/35 because you multiply the 2 denominators and numerators together. -1 times 1 is -1, 7 times 5 is 35. Make that as a fraction to get -1/35.

Answer:

(i) ∠CDF = 86°

(ii) ∠BAD = 141°

Step-by-step explanation:

(i) Angles CDF and GFD are "alternate interior" angles, so are congruent.

∠CDF = 86°

(ii) Angles BAD and CDA are "alternate interior angles, so are congruent. Angle CDA is the sum of angles CDH and HDA. Angle CDH is supplementary to angle CDF, so is ...

∠CDH = 180° -∠CDF = 180° -86° = 94°

Then ...

∠CDA = ∠CDH +∠HDA = 94° +47°

∠CDA = 141°
