Answer:
Area of Mrs. Rockwell's lot is equal to the area of Mr. Brown's lot
Step-by-step explanation:
We can suppose the dimensions of Mrs. Rockwell's lot to be:
Length = x
Width = y
Then, we can write the dimensions of Mr. Brown's lot as:
Length = half as long as Mrs. Rockwell's lot
Length = 0.5x
Width = twice as wide as Mrs. Rockwell's lot
Width = 2y
Area of Mrs. Rockwell's lot = Length * Width
= x*y
Area of Mrs. Rockwell's lot = xy
Area of Mr. Brown's lot = 0.5x*2y
Area of Mr. Brown's lot = xy
<u>Area of Mrs. Rockwell's lot </u><u>is equal</u><u> to the area of Mr. Brown's lot, as calculated above</u>.
Answer:
no. of senior citizens=x
no.of other people=7-x
cost=30=k(7-x)+(k/2)x. k is the cost of a ticket
k(7-x+x/2)
k(7-x/2)-30=0
k=60/(14-x)
now do trial and error substitution for (x<7) until u get a whole number for k also (k<30). if you have the skills you can suggest the number yourself
ie x= 2, k=5$

Answer:
10 quarters
x=10
Step-by-step explanation:
25 pennies equals to .25 ⊄
6 nickels equals to .30⊄
2 dimes equals to .20⊄
Add it up: 25+30+20=75⊄
You will then subtract .75 from our total:
3.25-.75=2.50
You need 2.50 in quarters; remember .50 for two quarters and 1.00 for four.
Eight quarters will equal 2.00
and two quarters equals 50.
Add it up, 10 for 2.50.
You will have 10 quarters.
X=10
One inch. There are 2.54 cm in an inch.
