Ali bought 2kg of potato and 3kg of onion. The price of the onion is 50 cents less
than potato. He paid $10 to the cashier and get back $1.50. What is the price for 1kg
of onion ?
Answer:
1kg of onion is $1.5
Step-by-step explanation:
He paid $10 and got $1.50 back, meaning that the total price for the 2kg and 3kg of the potato and onion is:
10 - 1.5 = $8.50
Now, equating the prices of the two (take x as the cost of the potato per kg and take y as the cost of the onion per kg):
x -0.5 = y
x - y = 0.5 ---- Eq 1
Equating the total costs:
2x + 3y = 8.5 ---- Eq 2
Multiplying Eq 1 by 2:
2x - 2y = 1 ---- Eq 1'
Subtracting Eq 2 from Eq 1':
2x - 2x +3y - (-2y) = 8.5 - 1
5y = 7.5
y = 1.5
Substituting this into the first equation:
x - 1.5 = 0.5
x = 2
Hence,
the cost of the Potato is $2, and
the cost of the Onion per kg is $1.5
Hope this helps, and have a wonderful time ahead on Brainly!
Find the difference of 2/3 and 3/5.
Answer:
1/15
Step-by-step explanation:
2/3*5/5 - 3/5*3/3( we are multiplying and dividing by the same number in order to get the same denominator. as 5/5 = 1 and 3/3= 1)
2/3*5/5 - 3/5*3/3

$ 42.05 ÷ 1.06$ 39.66 per poundArea and perimeter for this rectangle
Answer:
perimeter = (8x + 3mm + 5mm) ×2
area = (8x + 3mm) × 5mm
Answer:
Perimeter: 48mm
Area: 95mm
Step-by-step explanation:
Perimeter=2(l+w)
2((8x+3)+5)
-8x=2(3+5)
-8x=2(8)
-8x=16
x=2
2((8(2)+3)+5)= 48
So the perimeter is 48mm
Area=wl
l=19mm
w=5mm
19*5=95mm
So the area is 95mm

9. The endpoints of a diameter of a circle are A (2,1) and B(5,5). Find the area of the circle in terms of . (1 point)
25
O
IT square units
O 10 square units
O 255 square units
O 57 square units
Answer:
Area of the circle is 6.25π sq.unit
Step-by-step explanation:
The centre of the circle is at the mid point of a diameter. Th mid point of the diameter is at (5+22,5+12)or(72,3),which is centre. Radius is the distance from end point (5,5)to centre (72,3)∴r=√(5−72)2+(5−3)2=√1.52+4=√6.25=2.5∴
Area of the circle is Ac=π⋅r2=π⋅2.52=6.25π sq.unit[Ans]
The Area of Circle whose endpoints of a diameter of a circle are A (2,1) and B(5,5) is 6.25 sq unit.
What is Distance Formula?If there are two points in the coordinates plane as P(a, b) and Q(c, d) then the distance between these two points are
PQ = √(c- a)² + (d-b)²
We have the endpoints of a diameter of a circle are A (2,1) and B(5,5).
Now, using Distance Formula
d= √{(x2 - x1)² + (y2 - y1)²}
Here, x1 = 2; y1 = 1; x2 = 5; y2 = 5
d = √{(5 - 2)² + (5 - 1)²}
d = √{(3)² + (4)²}
d = √{9 + 16}
d = √25
d = 5 unit
Now, Area of Circle
= πr²
= 3.14 x 2.5 x 2.5
= 6.25π sq units

2x+10y=20 and passes through (2,3)
Answer:
No, it doesn't pass throughStep-by-step explanation:
As, if we put the value (2,3) in the equation then,
2x + 10y = 20
=> 2(2) + 10(3) = 20
=> 4 + 30 = 20
=> 34 ≠ 20
Hence,
2x+10y=20 does not pass through (2,3)

Convert numbers 359 to binary
Expand 359 as a sum of the largest powers of 2 that you can:
359 = 256 + 103
359 = 256 + 64 + 39
359 = 256 + 64 + 32 + 7
359 = 256 + 64 + 32 + 4 + 3
359 = 256 + 64 + 32 + 4 + 2 + 1

Ana and Ling are solving |3x + 14| = -6x.
Is either of them correct?...............................
Explain your reasoning.
Answer:
No! Both are wrong!
Step-by-step Explanation:
the value of absolute function, (|.|) is always positive
that means -6x always has to be positive
and for -6x to be positive x has to be negative
(since, two negatives make a positive)
therefore, the value of x to the equation will be a negative value and not a positive one.
Ana thinks both positive and negative values of x will be the solution, whereas Ling thinks negative value of x can't be a solution. So, they're both wrong.
ONLY negative value of x will be the solution.

Write an equation of the line in slope intercept form for (0,3) and (4,2)
Answer: 13
Step-by-step explanation:
Step-by-step explanation:
the slope is the y/x ratio of the y and x coordinate differences when going from one point to the other. and it is always the factor of x in the equation.
x changes by 4 units (from 0 to 4), y changes by -1 unit (from 3 to 2).
so, the slope is -1/4.
the intercept means the intercept with the y-axis. and that means the y value when x = 0. which is given already by the first point : 3
so, the equation is
y = -1/4 x + 3
