Answer:
Part A:
- angle ACB= 60° (ABC equilateral triangle.)
- Angle ECD=EDC= (180°-32°)/2= 148/2= 74° (sum of angles in a triangle is equal to 180, and triangle ECD is isosceles since it's given that CE=DE.
- x= 180°-(60°+74°)
= 180°-134°
= 46°
x= 46°
Part B:
120°

Since in 1990 there are 28%, we need to figure out when it gets to 31%. In addition, since it increases by 0.6% every year, we can say that 0.6x+28 (since 28 is the base value) is the percentage of babies born in wedlock every year. Therefore, to get 0.6x+28=31, we subtract 28 from both sides to get 0.6x=3
Dividing both sides by 0.6, we get x=5=the amount of years it takes to get 31% of babies born in wedlock. Since 1990 is the base value (we start from there!), we add 5 to that to get 1990+5=1995 as the yar
Answer: Elena spent $3.6 +x more than Tammy.
Step-by-step explanation:
Let the cost of each cherry be 'x'.
Cost of watermelon for Elena = $7.75
Cost of 5 pounds of cherries = 5x
So, Equation for Elena would be
Cost of pineapple = $4.15
Number of pounds of cherries = 4
So, Equation for Tammy would be
Now, Elena spent more than Tammy by
Hence, Elena spent $3.6 +x more than Tammy.
