Answer:
I'll explain below, just follow the directions. I can't directly draw it.
Step-by-step explanation:
find the length and the width of a rectangle whose perimeter is 18 ft
2L + 2W = 18
simplify, divide by 2
L + W = 9
L = (9-W)
:
whose area is 20 square feet
L*W = 20
Replace L with (9-W)
W(9-W) = 20
-W^2 + 9W - 20 = 0
Multiply by -1, easier to factor
W^2 - 9W + 20
Factors to
(W-4)(W-5) = 0
Two solutions
W = 4 ft is width, then 5 ft is the Length
and
W = 5 ft is the width, then 4 ft
Answer:
The number of girls is at most 9 girls
y ≤ 9
Step-by-step explanation:
The chess clubcab have at most 36 members.
At most means : Less than or equal to 36 members and it is represented by the inequality = ≤
The are 3 times as many boys as girls in the chess club.
Boys = x
Girls = y
Hence,
x = 3y
Which inequality could be used to determine the possible number of girls, x, in the chess club?
Therefore,
x + y≤ 36
3y + y ≤ 36
4y ≤ 36
y ≤ 36/4
y ≤ 9
Girls = y
The number of girls is at most 9 girls
Answer:
The answer is 2 and 1/4.
Step-by-step explanation:
You have to do 9 x 1/4 and then you get 2 & 1/4
Answer:
<h2>Jimmy is 16 old.</h2>
Step-by-step explanation:
J - the age of Jimmy John
50 - the age of Papa John
3J + 2 - the age of Papa John
The euaqtion:
3J + 2 = 50 <em>subtract 2 from both sides</em>
3J + 2 - 2 = 50 - 2
3J = 48 <em>divide both sides by 3</em>
3J/3 = 48/3
J = 16
