Step-by-step explanation:
Let the length of one side of the original square be a.
The length of one side of the new square is (a+7) feet,
the area of the second square is
taking the square root of both sides:
a+7=11
a=4
Answer: 4 feet
Answer:
1/3x - 1/3
Step-by-step explanation:
First off, we can write this the words as a mathematical equations so its easier to work with:
1/3 (x - 1)
Now we can use distributive property and finally simplify this equation:
1/3 (x-1)
1/3x - 1/3 x 1
1/3x - 1/3
Answer: the price of each bagel is $0.55 and each doughnut is $0.7
Step-by-step explanation:
Let x represent the price of each bagel.
Let y represent the price of each doughnut.
One of them bought 7 bagels and 5 doughnuts, and paid $7.35. This is expressed as
7x + 5y = 7.35 - - - - - - - - - - - - - 1
The other customer bought 4 bagels and 6 doughnuts, and paid $6.40. This is expressed as
4x + 6y = 6.4 - - - - - - - - - - - - - 2
Multiplying equation 1 by 4 and equation 2 by 7, it becomes
28x + 20y = 29.4
28x + 42y = 44.8
Subtracting, it becomes
- 22y = - 15.4
y = - 15.4/ - 22
y = 0.7
Substituting y = 0.7 into equation 1, it becomes
7x + 5 × 0.7 = 7.35
7x + 3.5 = 7.35
7x = 7.35 - 3.5
7x = 3.85
x = 3.85/7
x = 0.55
