To rent 7 movies, he needs 2(7) + 12 = $26.
But he has only $10. So he needs more 26 - 10 = $16.
Answer:
1
Step-by-step explanation:
So for this type of problem we use the formula with each variable (besides m which is slope) representing a different coordinate. (e.g. -3 could be in this case.) First, let's define which is which:
(3,2):
(-2,-3):
Now we need to replace the variables with their known values:
Next, let's do the subtraction to simplify:
And we can complete the division (all fractions are division!) to simplify even further:
Therefore, the slope of the line passing through the points (3,2) and (-2,-3) is 1.
Answer:
Step-by-step explanation:
25 is equivalent to 820 because 2 x 20 = 5 x 8 = 40. 410 is equivalent to 820 because 4 x 20 = 10 x 8 = 80. 615 is equivalent to 820 because 6 x 20 = 15 x 8 = 120.
Answer:
m∠<em>DEB</em> = _<u>70</u>_°
m∠<em>BCD</em>= _<u>110</u>_°
m∠<em>EAB</em>= _<u>73</u>_°
Step-by-step explanation:
<u>To find ∠</u><em><u>DEB</u></em><u>: </u>
Take the angle of ∠<em>EDC</em>, which is 110°. We know the total degree in a triangle is 180°. So, we do 180° - 110° to get 70°.
<u>To find ∠</u><em><u>BCD</u></em><u>: </u>
Because <em>EBCD</em> is an isosceles trapezoid, this means that ∠<em>D</em> and ∠<em>C</em> both have the congruent angles. Since we know ∠<em>EDC</em> is 110°, this means that ∠<em>C</em> is also 110°.
<u>To find ∠EAB: </u>
We know that m∠<em>ABC</em> is 133° and ∠<em>DEA</em> is 114°. However, both angles count both the triangle and trapezoid. Previously we figured out that ∠<em>DEB</em> is 70°. We'll take the angle of ∠<em>DEA</em> and subtract the angle of ∠<em>DEB</em> from it, which gets us 44°. To figure out the angle of ∠<em>B</em>, we take the angle of ∠<em>ABC</em> and subtract 70° or the angle of ∠<em>DEB</em>, which gets us 63°. Now we take the total degree of a triangle, 180° and minus both 44° and 63° from it, which is 73°.

Well it really depends what u r solving for. So for perimeter u could add both X’s so 2x, and then add 10+2 which is 12. So it would be 2x+12. Not 100% right but I tried hope this helps and good luck!
