Suppose that Eldi has x years old now :
x + 4 = 3 × ( x - 10 )
x + 4 = 3x - 30
Add both sides 30
x + 4 + 30 = 3x - 30 + 30
x + 34 = 3x
Subtract both sides x
x - x + 34 = 3x - x
34 = 2x
2x = 34
Divide both sides by 2
2x ÷ 2 =34 ÷ 2
x = 17
_____________________________
Thus Eldi is 17 .

Step-by-step explanation:
Cedarville
Year 1
1200 * 8% = 96 people
At the end the population is 1296
Year 2
1296 * 7% =90.72
1296+90.72 =1386.72 people
Pinedale
1200*15%=180
1200+180 = 1380
Cedarville has more people at the end of 2 years by 6.72 people
Answer:
<u>135 cubes</u>
Step-by-step explanation:
Volume of cuboid :
- 45 x 16 x 12
- 720 x 12
- 8,640 cm³
Volume of a small cube :
Number of cubes :
- n = 8,640/64
- n = <u>135 cubes</u>
The absolute value is the distance from 0, so it would be 4 and -4
1.6 × 1.6 × 1.6 × 1.6 = 6.5536
