820,445 in expanded form: 800,000 + 20,000 + 400 + 40 + 5
Let's start by moving all like terms to their own sides:
-18 = -3x + 6
3x = 6 + 18
3x = 24
x = 8
X is the domain and y is the range
Answer:
![1.3\ days](https://tex.z-dn.net/?f=1.3%5C%20days)
Step-by-step explanation:
step 1
Find the units rate of the first glacier
![\frac{75}{3}=25\frac{meters}{day}](https://tex.z-dn.net/?f=%5Cfrac%7B75%7D%7B3%7D%3D25%5Cfrac%7Bmeters%7D%7Bday%7D)
using proportion
![\frac{25}{1}\frac{meters}{day}=\frac{200}{x}\frac{meters}{days}\\ \\x=200/25\\ \\x=8\ days](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B1%7D%5Cfrac%7Bmeters%7D%7Bday%7D%3D%5Cfrac%7B200%7D%7Bx%7D%5Cfrac%7Bmeters%7D%7Bdays%7D%5C%5C%20%5C%5Cx%3D200%2F25%5C%5C%20%5C%5Cx%3D8%5C%20days)
step 2
Find the units rate of the second glacier
![\frac{107.5}{5}=21.5\frac{meters}{day}](https://tex.z-dn.net/?f=%5Cfrac%7B107.5%7D%7B5%7D%3D21.5%5Cfrac%7Bmeters%7D%7Bday%7D)
using proportion
![\frac{21.5}{1}\frac{meters}{day}=\frac{200}{x}\frac{meters}{days}\\ \\x=200/21.5\\ \\x=9.3\ days](https://tex.z-dn.net/?f=%5Cfrac%7B21.5%7D%7B1%7D%5Cfrac%7Bmeters%7D%7Bday%7D%3D%5Cfrac%7B200%7D%7Bx%7D%5Cfrac%7Bmeters%7D%7Bdays%7D%5C%5C%20%5C%5Cx%3D200%2F21.5%5C%5C%20%5C%5Cx%3D9.3%5C%20days)
step 3
Find the difference
![9.3\ days-8\ days=1.3\ days](https://tex.z-dn.net/?f=9.3%5C%20days-8%5C%20days%3D1.3%5C%20days)
Answer:
11
Step-by-step explanation:
Opposite sides are congruent at parallelograms. So x+16 must be equal to 2x+5. Solve the equation;
2x+5 = x+16
x = 11 .
