Ulleksa [173]

Answer:

Step-by-step explanation:

c + f = 10 (the coach tickets + first class tickets = 10)...there is 10 people

160c + 1230f = 6950....each coach ticket is 160 and each first class ticket is 1230.....and when added, they equal 6950 (for the airfare)

c + f = 10.....c = 10 - f

160c + 1230f = 6950

sub in 10 - f for c

160(10 - f) + 1230f = 6950

distribute the 160 thru the parenthesis

1600 - 160f + 1230f = 6950

combine like terms

1600 + 1070f = 6950

subtract 1600 from both sides

1070f = 6950 - 1600

1070f = 5350

divide both sides by 1070

f = 5350/1070

f = 5 <===== she bought 5 first class tickets

c + f = 10

we found f to be 5...so sub in 5 for f and find c, the coach tickets

c + 5 = 10

c = 10 - 5

c = 5 .......and she bought 5 coach tickets

check...

160c + 1230f = 6950

160(5) + 1230(5) = 6950

800 + 6150 = 6950

6950 = 6950 (correct)....so it checks out

5 coach and 5 first class

Write the Arabic value of MDCCXLIV
iris [78.8K]

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>
