Answer:
Step-by-step explanation:
let $p, $c and $d represents the costs of popcorn, candy and a drink respectively. If the popcorn was three times as expensive as the candy then;
p = 3c.... 1
If the drink was twice as expensive as the candy then d = 2c .... 2
If Eva spent a total sum of $10.50 at the movies, the equation that represents the situation will be p + c + d = $10.50 .... 3
Substituting equation 1 and 2 into 3;
3c + c + 2c = $10.50
6c = $10.50
<em>Hence the equation to represent the situation is 6c = $10.50 where c represents the cost of the candy.</em>
<em></em>
b) To get c from the equation 6c = $10.50, we will simply divide both sides by the coefficient of c i.e 6 as shown
6c/6 = $10.50/6
c = $1.75
<em>Hence the value of c is $1.75</em>
<em></em>
<em>c) </em>The equation representing Eva's drink in terms of the candy is expressed as d = 2c
Substituting c = $1.75 into the equation will give;
d = 2(1.75)
d = 3.5
<em></em>
<em>Hence the cost of Eva's drink is $3.50</em>
Answer:
.6
Step-by-step explanation:
Steps to solve:
-20 < 4 - 2x
~Subtract 4 to both sides
-24 < -2x
~Divide -2 to both sides
12 > x
Best of Luck!

Answer:
You got it right. Triangle DAC
Step-by-step explanation:
Line segment DA is a perpendicular bisector(it cuts line segment CE perfectly in half making line segment AE an CA congruent. Since the triangle share line segment DA that makes them congruent by the SAS postulate
