M = 1,000
D = 500
C = 100
L = 50
X = 10
V = 5
I = 1
MDCCXLIV
M = 1,000
DCC = 500 + 100 + 100 = 700 (smaller after larger, then adding)
XL = 50 - 10 = 40 (smaller before bigger, then subtraction)
IV = 5 - 1 = 4 (smaller before bigger, then subtraction)
<h3>MDCCXLIV = 1,000 + 700 + 40 + 4 = 1,744</h3>
Answer:
Step-by-step explanation:
-8( - 20+ (-4)2) = 32
-8(-20 + 16) = 32
-8(-4) = 32
32 = 32
Answer:
y=5x
Step-by-step explanation:
The table is given as:
x | y
2 | 10
4 | 20
6 | 30
8 | 40
A proportional relation satisfy the relation: 
We can substitute any x value with the corresponding y-value and solve for k.
When x=2,y=10
This implies that:
Divide both sides by 2 to get:
Hence the equation is 
Pattie runs at 5 ft/sec
She has got a head start of 15 feet.
So after 1 second, Pattie runs = (5+15) ft
<span>
= 20 </span>
ft
After 2 second Pattie runs = (20+5)ft
= 25 ft
After 3 second Pattie runs = (25+5) ft
= 30 ft
After 4 seconds Pattie runs = (30+5) ft
= 35 ft
After 5 seconds Pattie runs = (35+5) ft
= 40 ft
After 6 seconds Pattie runs = (40+5) ft
= 45 ft
Now Keith runs at 8 ft/sec
After 1 second Keith runs = 8 ft
After 2 second Keith runs = (8+8) ft
= 16 ft
After 3 second Keith runs = (16+8) ft
= 24 ft
After 4 second Keith runs = (24+8) ft
= 32 ft
After 5 second Keith runs = (32+8) ft
= 40 ft
After 6 second Keith runs = (40+8) ft
= 48 ft
So Pattie will stay ahead of Keith upto 4 seconds. In the 5th second Pattie and Keith will be level and in the 6th second Pattie will be overtaken by Keith.
