Answer:
So W is going to stand for width and L is going to stand for length.
L= 2W+6
78=2L + 2W
Those are the two equations you will use. So plug in L=2W+6 into the other one and solve.
78= 4W+12 +2W
(simplify)
78=6W+12
(-12 from both sides)
66=6W
(divide by 11)
W=11
Replug W into your equation to find L.
L=22+6
(simplify)
L=28
I hope this is right

Step-by-step explanation:
4% of 33,000 commission is 1,320
Answer:
Since, Robin is twice as old as Earl,
Thus, the ratio of the age of robin and earl = 2 : 3
Let the age of robin = 2x and the age of earl = 3x
Where x is any number,
According to the question,
3×Age of Adam = 2x + 6
Age of Adam = 1/3(2x+6)
Also, Age of Adam = Age of earl - 8
⇒ 1/3(2x+6) = 3x - 8
⇒ 2x + 6 = 9x - 24
⇒ -7x = - 30
⇒ x = 30/7
Hence, the age of Robin = 2x = 2×30/7 = 60/7 years
The age of Earl = 3x = 3×30/7=90/7 years
The age of Adam = 34/7 years
Answer:
176 sweets
Step-by-step explanation:
162 - 30 = 132 this finds the 3/4 before he purchased more sweets.
132 divided by 3 = 44 This finds how many thirds their are. (We do 3 not 4 because 1/4 is already gone and there are only 3rds lefts.)
44 x 4 = 176 This finds the total before he purchased more.
Hope this helps!
