The sum of two whole numbers is 64 and their difference is 20. What is the bigger number?
Answer:
42 and 22 are the numbers
Step-by-step explanation:
Let the numbers be x and y
[tex]x + y = 64[/tex]
[tex]x - y = 20[/tex]
On adding both
[tex]x + y + x - y = 64 + 20[/tex]
[tex]2x = 84[/tex]
[tex]x = \dfrac{84}{2} [/tex]
[tex]x = 42[/tex]
Using 1
[tex]42 + y = 64[/tex]
[tex]y = 64 - 42[/tex]
[tex]y = 22[/tex]

9514 1404 393
Answer:
Rs 3200
Step-by-step explanation:
The actual selling price was 20% below the cost price, so was ...
sp = cp(1 -20%) = 0.80cp
Had the selling price been raised, the selling price would have been 5% above the cost price:
sp +800 = cp(1 +5%) = 1.05cp
Subtracting the first equation from the second gives ...
(sp +800) -(sp) = (1.05cp) -(0.80cp)
800 = 0.25cp . . . . . . . simplify
3200 = cp . . . . . . . . multiply by 4
The cost price was Rs 3200.

Convert the mixed number to an improper fractions.
457
Note: Use the "/" sign as a fraction bar.
Answer:
1. -29/156 2. 38/45 3. 29/45 4. 113/24 or about 4.7 5. 457/1, 914/2, 1371/3
Step-by-step explanation:
3/13 - 5/12 can be simplified to 36/156 - 65/156. Subtract this and you get -29/156
4/9 + 2/5 can be simplified to 20/45 + 18/45. Add this and you get
38/45
5/8 - 2/9 can be simplified to 45/72 - 16/72. Subtract this and you get
29/45
3 1/2 + 2 5/12 can be first made irrational to 7/2 + 29/24. This can be simplified to 84/24 + 29/24
113/24 or about 4.7
Not sure about the 457, but to convert it, you multiply it by whatever denominator you have. For example
1x457 = 457/1
2x457 = 914/2
And finally 3x457 = 1371/3
Kollie was born in January
2000. How old wos he five
years ago?
Answer:
He was 16 years old.
Step-by-step explanation:
[tex] = (2021 - 5) - 2000 \\ = 2016 - 2000 \\ = 16[/tex]
Answer:
16 years old.
Step-by-step explanation:
Today's year is 2021
So,
[tex]2000 + 21 = 2021[/tex]
So, whoever's born in 2000, would be 21 years old in 2021. How old was Kollie five years ago?
[tex]21 - 5 = 16[/tex]
Kollie was 16 years old.
A fair fare. Three strangers, Bob, Mary, and Ivan, meet at a taxi stand and decide to share a cab to cut down the cost. Each has a different destination, but all the destinations are on the highway leading from the airport, so no circuitous driving is required.

How much should each person pay?
Answer:
$21 the minimum Bob has to may will be the amount payed regardless of the number of passengers in the taxi

Step-by-step explanation:
[tex]8x - 3 = 5 + 4y[/tex]
Isolate y first subtract 5 from both sides
[tex]8x - 8 = 4y[/tex]
Divide both sides by 4.
[tex] \frac{8x - 8}{4} = y[/tex]
[tex]2x - 2 = y[/tex]
y= 1
Step-by-step explanation:
Solve for y:
8x - 3 = 5 + 4y
8x = 4y + 5+3
Divide both sides by 8
x = 1÷2y + 1
plug into equation
8 (1÷2y +1) - 3 = 5 + 4y
Distribute
8÷2+ 8 - 3 = 5 + 4y
4 + 5 -5 = 4y
Combine like item
4 = 4y
divide both sides by 4
y= 1

(-3, 2)
Step-by-step explanation:
when the point is rotated through 90∘ about the origin in the counterclockwise direction then the point M(h,k) takes the image M′(−k,h)

Answer:
see below
Step-by-step explanation:
We can use the distance formula
11. d =sqrt( (y2-y1)^2 + (x2-x1) ^2)
= sqrt( (-3 --5)^2+(-6 - -1)^2)
= sqrt( (-3+5)^2 + (-6+1)^2)
= sqrt( 2^2 + (-5)^2)
= sqrt (4+25)
= sqrt(29)
12. Using the points ( 1,3) and (4,-1)
d =sqrt( (y2-y1)^2 + (x2-x1) ^2)
= sqrt( (-1-3)^2+(4-1)^2)
= sqrt( (-4)^2+(3)^2)
= sqrt(16+9)
=sqrt(25)
=5
Answer:
11. d =sqrt( (y2-y1)^2 + (x2-x1) ^2)
= sqrt( (-3 --5)^2+(-6 - -1)^2)
= sqrt( (-3+5)^2 + (-6+1)^2)
= sqrt( 2^2 + (-5)^2)
= sqrt (4+25)
= sqrt(29)
12. Using the points ( 1,3) and (4,-1)
d =sqrt( (y2-y1)^2 + (x2-x1) ^2)
= sqrt( (-1-3)^2+(4-1)^2)
= sqrt( (-4)^2+(3)^2)
= sqrt(16+9)
=sqrt(25)

On a number line, suppose point E has a coordinate of −3,and EG=8.What are the possible coordinates of point G?
The possible coordinates for G are?
Please help!
The measure of side BC is 30 units.
Given:
Points A, B, and C are collinear and B lies between A and C.
[tex]AC=48[/tex]
[tex]AB=2x+2[/tex]
[tex]BC=3x+6[/tex]
To find:
The value of BC.
Solution:
Points A, B, and C are collinear and B lies between A and C. So,
[tex]AB+BC=AC[/tex] [Segment addition postulate]
[tex](2x+2)+(3x+6)=48[/tex]
[tex]5x+8=48[/tex]
Subtract 8 from both sides.
[tex]5x=48-8[/tex]
[tex]5x=40[/tex]
Divide both sides by 5.
[tex]\dfrac{5x}{5}=\dfrac{40}{5}[/tex]
[tex]x=8[/tex]
Now,
[tex]BC=3(8)+6[/tex]
[tex]BC=24+6[/tex]
[tex]BC=30[/tex]
Therefore, the value of BC is 30.

The possible coordinates for G are -11 and 5.
Given:
On a number line, suppose point E has a coordinate of [tex]-3[/tex], and [tex]EG=8[/tex].
To find:
The possible coordinates of point G.
Solution:
Either point G lies 8 units left of point E or 8 units right of point E.
[tex]G=-3-8[/tex]
[tex]G=-11[/tex]
And
[tex]G=-3+8[/tex]
[tex]G=5[/tex]
Therefore, the possible coordinates for G are -11 and 5.
