4 units is the width.
10 units is the length. If we put this in, we get (l*w) 10*4 for the area, which is 40 square units. This is a true statement. Also, 4*2 is 8, and 2 more units than 8 is 10 units.
Answer:
10
Step-by-step explanation:
AB + BC = AC and AC = 14
x + 15 + 2x + 32 = 14 add like terms
3x + 47 = 14 subtract 47 from both sides
3x = -33 divide both sides by 3
x = -11 now the length of BC
2x + 32 replace x with -11
2*(-11) + 32 = 10
Answer:
Step-by-step explanation:
Let x = the number of $20 bills.
Then x + 6 = the number of $5 bills and
20x + 5(x + 6) = 455
x = 17 = number of $20 bills
x + 6 = 17 + 6 = 23 = number of $5 bills
Check:
OK.
Answer:
15
Step-by-step explanation:
x + 3 = 2(x - 6)
x + 3 = 2x - 12
-1x = -15
=15
Just add them all up and divide by how many numbers there are
6+12+22+16=56
56 divided by 4 = 14
14 is the mean
