Answer:
see explanation
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is the length and w the width )
perimeter of rectangle A = 2(7) + 2(5) = 14 + 10 = 24 in
perimeter of rectangle B = 2(4x - 3) + 2x = 8x - 6 + 2x = 10x - 6 in
Equating the two gives
10x - 6 = 24 ( add 6 to both sides )
10x = 30 ( divide both sides by 10 )
x = 3
Thus
length of rectangle B = 4x - 3 = 4(3) - 3 = 12 - 3 = 9 in
Width of rectangle B = x = 3 in
8,000,000 + 200,000 + 5,000
Answer:
32 people are on the crew
Step-by-step explanation:
If 8 people equal 25%, you can multiply it by 4 to get 100%. 24 people are women and 8 are men on the crew.
(a) Let x be the cost of one of Brian's items, then cost of all 4 items bought by Brian will be 4x.
We have been given that Chris bought 3 items that each cost $2.50 more than Brian’s items each cost. The price of each item bought by Chris will be x+2.5. Therefore, the cost of all 3 items bought by Chris will be
.
(b) We are told that Brian and Chris both paid the same amount of money, so we can equate costs of Brian's 4 items and Chris's 3 items as:

Now let us solve for x by distributing 3.



Therefore, cost of Brian's each item is $7.5.
Now let us find price of Chris's each item.

Therefore, cost of Chris's each item is $10.
(c) Now let us check our solution by substituting x=7.5 in
.



We can see that both Brian and Chris spent equal amount of money that is $30, therefore, our solution is correct.
