The answer for <span>2.85 centimeters in expanded form is </span>2 centimeters+ .85 centimeters= 2.85 centimeters
Answer:
80
Step-by-step explanation:
1 centimeter is equal to 20 feet so if you have 4 cm, it's will 4*20
Also the other two answers are too small to be possible
Set up the equation
x = the smaller number
x + 15 = the larger number
x + x + 15 =39
solve for x
this will be the smaller number
add 15 to get the larger number
Answer:
61.8 and 118.2
Step-by-step explanation:
Let's call one angle A and the other B. Supplementary angles add to 180, so A+B=180. If B=A+56.4, then we can rewrite the equation in terms of A, or A+(A+56.4)=180 or 2A+56.4=180. To solve, first subtract 56.4 from each side and then divide by 2 to get A=61.8. Since the angle is supplementary, all we need to do to find B is subtract A (61.8) from 180 to get B=118.2.
