The area of the field where the length of each side is increased by 10% is 48.4
.
Step-by-step explanation:
The given is,
A rectangle field has an area of 40 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
If one side of the field is 3 cm longer than the other side
The length of new area in each side is increased by 10%
Step:1
Let,
- One side of rectangle
- Other side of rectangle
From given.
-
+3
Formula for area of rectangle,
40 = ( b+3) × b
40 =
+ 3b
Solving the above the equation,
b = 5 cm
l = 8 cm
Step:2
If the area of rectangle increased by 10%,
l = 8 + ( 8 ×
)
= 8.8
b = 5 + ( 5 ×
)
= 5.5
Area of rectangle is,
a = ( 8.8 × 5.5 )
= 48.4 square centimeters
Result:
The area of the field where the length of each side is increased by 10% is 48.4
, if a rectangle field has an area of 40 square centimeters and one side of the field is 3 cm longer than the other side.
The complete question is
"Lisa has $150 at most to spend on clothes. She wants to buy a pair of jeans for $58 and will spend the rest on t-shirts that cost $14 each.
Explain what your solution means using complete sentences. How many t-shirts can she buy? Focus your answer on the difference between an equation and an inequality."
The expression that represents the number of t-shirts that Lisa can purchase is 14x + 58 = 150. The number of shirts that can be bought is 6.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Lisa has $150 at most to spend on clothes. She wants to buy a pair of jeans for $58 and will spend the rest on t-shirts that cost $14 each.
Let the number of shirts be x. The expression will be:
= (14 × x) + 58 = 150
14x + 58 = 150
Solving the expression will be:
14x + 58 = 150
14x = 150 - 58
14x = 92
x = 92/14
x = 6.5
The number of shirts that can be bought is 6.

Answer: 16 4/7
Step-by-step explanation:
Instead of subtracting a fraction from a whole number you could change the whole number into a fraction...
17= 16 7/7, which has the same value as 17
16 7/7- 3/7 equals 16 4/7
(7-3= 4)
Answer:
(1,5)
Step-by-step explanation:
The x coordinate of the midpoint is found by adding the x coordinates and dividing by 2
(6+-4)/2 = 2/2 =1
The y coordinate of the midpoint is found by adding the x coordinates and dividing by 2
( (8+2)/2 = 10/2 = 5
The mid point is (1,5)
