Answer: In 0.04, the digit 4 is in the hundredths place. In 0.004, the digit is in the thousandths place. The digit 4 has a greater value in 0.04 because it's value is 10 times as much as it's value in 0.004.
Step-by-step explanation: You didn't give the options but i hope this answer helps!
The first step is to define the system of equations.
Take x and y as the cost of a small box and a large box respectively.

Solve the system.



A small box costs $4 and a large box costs $4 too.
Answer:
34+(-12) =22
Step-by-step explanation:
because they said that adding numbers but they didn't said that negative Or positive. so i took those numbers
A)
The question tells us that
y + z = 180
And
y=3x+20
z=x
So we put them in the first formula:
y + z = 180
(3x + 20) + x = 180
Add and get x to one side:
4x + 20 = 180
4x + 20 - 20 = 180-20
4x = 160
Divide both sides by 4
x = 40
B)
Put x back in to equation to get size of each angle:
Y =3x +20
Y=3(40)+20
Y=120+20
Y=140
Z=x
Z=40
Verify: y+z=180
140+40=180
180=180
