Answer: Orange = 5 rupee
Apple = 6 rupees
Step-by-step explanation:
Let the cost of an orange be x
Let the cost of an apple be y
We can form an equation from the question given which will be:
5x + 3y = 43 ......... i
2x + 4y = 34 ......... ii
Multiply equation i by 2
Multiply equation ii by 5
10x + 6y = 86 ........ iii
10x + 20y = 170 ..... iv
Subtract iii from iv
14y = 84
y = 84/14
y = 6
An apple cost 6 rupees
Since from equation ii
2x + 4y = 34
2x + 4(6) = 34
2x + 24 = 34
2x = 34 - 24
2x = 10
x = 10/2
x = 5
An orange cost 5 rupee

A T.V. is regularly priced at $600, but it is on sale for 20% off. What's the sale price?
Answer:
$480
Step-by-step explanation:
multiply the normal price $600 by 20 then divide it by one hundred
the discount is $120
the sales price is subracting the discount of $120 from the original price of $600 then get $480 as the sales price.
Answer:
Step-by-step explanation:
Method 1: Subtract 20% from 100%, obtaining 80%, and then multiply the regular price ($600) by the decimal equivalent 0.80. We get $480 as the sale price.
Method 2: Calculate the amount of the discount by multiplying $600 by 0.20, obtaining $120. Then subtract this discount from the regular price, $600, obtaining $480.

Answer:
x = 7
Step-by-step explanation:
The sum of both angles are complementary that is;
6x + 48 = 90
6x = 90 - 48
6x = 42
x = 42/6
x = 7
Hence the value of x is 7

solusion
Length = L
Breadth = B
Original area = L x B
New area = A = L x (1 - 25%) x B x (1 + 40%)
A = L x B x 0.75 x 1.40 = L x B x 1.05
Therefore the area of the rectangle has increased by 5%.

Complete question is;
Craig went to an auction and bought five different items. Use the clues below to determine the price he paid for each item.
1. the chair was the most expensive item, which sold for $95.
2. The range of the prices of the five items was $75.
3. The stereo was the least expensive item.
4. Craig bought the TV for $25.
5. The video game player was $20 more than the TV.
6. The bed was $60 more than the stereo.
Answer:
Cost of chair = $95
Cost of stereo = $20
Cost of TV = $25
Cost of video game player = $45
Cost of bed = $80
Step-by-step explanation:
We are told the chair was the most expensive item which was $95.
the range of the prices of the five items was $75. This means;
Highest price - lowest price = $75
Since highest price is $95, then lowest price = 95 - 75 = $20
stereo is the least expensive item. Thus, stereo will cost $20.
TV was bought for $25
video game player was $20 more than the TV. Thus, video game player cost = 25 + 20 = $45
Bed was $60 more than stereo. Thus,
Cost of bed = $20 + $60 = $80
Jaiver bought a new TV for 479.76. He will make equal payments each month for 2 years . Estimate each payment.
Answer:
$19.99
Step-by-step explanation:
There are 12 months in a year, so in 2 years, there are 24 months.
Find how much each payment will be by dividing the cost by 24:
479.76/24
= 19.99
So, each payment will be $19.99
(4/9)^-1=
A. -4/9
B. 9/4
C. -9/4
Answer: 9/4
Step-by-step explanation: Think of [tex](\frac{4}{9})^{-1}[/tex]as [tex]\frac{4^{-1} }{9^{-1}}[/tex].
Now, we can change 4⁻¹ to 4¹ by moving it to the denominator and
we can change 9⁻¹ to 9¹ by moving it to the numerator.
So we have 9¹/4¹ which simplifies to 9/4.

1.6/.2 = 8. Now for the exponents.
When you divide like bases, you subtract the exponents. Our bases are both 10's, so they are like. Subtracting the exponents gives us 10³. So the answer is 8 × 10³, choice B.
Four friends raised a total of $730 for a local charity. Each friend raised the same amount of money. Model the total amount that the friends raised using the least number of base-ten blocks possible.
Answer:
Each friend raised $ 182.50.
Step-by-step explanation:
Given that four friends raised a total of $ 730 for a local charity, and each friend raised the same amount of money, for model the total amount that the friends raised the following calculation must be performed:
730/4 = X
182.5 = X
Therefore, each friend raised $ 182.50.

Solve the system of equations.
3x – 7y = 5
9y = 5x + 5
how do i solve this
Answer:
A = 61
Step-by-step explanation:
Complementary angles add to 90 degrees
A+B = 90
A +29 = 90
A = 90-29
A = 61
Answer:
∠A = 61°
Step-by-step explanation:
We know that sum of both angles of complementary angle is 90°.
∠A + ∠B = 90°
∠A + 29° = 90° ... (∠B = 29° - given )
subtract 29° from each side
∠A + 29° - 29° = 90° - 29°
∠A = 61°
Decide whether there is enough information to prove that △WXZ≅△YZX using the SAS Congruence Theorem.
A: yes; Because ZW≅XY, ∠W≅∠Y, and WX≅YZ, the two triangles are congruent by the SAS Congruence Theorem
B: yes; Because ZW≅XY, ∠W≅∠Y, and ZX≅XZ, the two triangles are congruent by the SAS Congruence Theorem.
C: no; There is one pair of congruent sides and one pair of congruent angles, but there is no other pair of congruent sides.
D: no; There are two pairs of congruent sides and one pair of congruent angles, but the angles are not the included angles.
Answer:
D
Step-by-step explanation:
ΔWXZ and ΔYZX
WZ ≅XY {Given}
ZX ≅ ZX {Reflexive property}
∠W ≅ ∠Y
But for SAS congruent the congruent angles should between congruent sides( WX & WZ should be congruent to ZY & XY respectively).
So it cannot be proved using SAS congruent
2w+2019 = 15w + 1838
Answer:
181/13 =w
Step-by-step explanation:
2w+2019 = 15w + 1838
Subtract 2w from each side
2w-2w+2019 = 15w-2w + 1838
2019 = 13w + 1838
Subtract 1838 from each side
2019 -1838 = 13w
181 = 13w
Divide each side by 13w
181/13 = 13w/13
181/13 =w

Given:
A figure of a rectangular prism with length l, width w and height h.
To find:
The surface area of the rectangular prism.
Solution:
The product of twice of the length l and the width w is:
[tex]2\times l\times w=2lw[/tex] ...(i)
The product of twice of the length l and the height is:
[tex]2\times l\times h=2lh[/tex] ...(ii)
The product of twice of the width w and the height h is:
[tex]2\times w\times h=2wh[/tex] ...(iii)
The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:
[tex]A=2lw+2lh+2wh[/tex]
[tex]A=2(lw+lh+wh)[/tex]
Therefore, the required expression is [tex]2(lw+lh+wh)[/tex].

Corresponding parts of similar triangle have the same proportions
Answer: A) [tex]\frac{AB}{XY} =\frac{AC}{XZ}[/tex]
Step-by-step explanation:
OK so if a figure is a dilation of another figure that means that is has the same angles but the sides are going to be smaller or bigger. Even though the sides are a different size they are proportional. So if I divided the length of AB over XY I'd get 5 since that is the scale factor. If I did that with AC over XZ I'd get 5 again because that is the scale factor. That's because they were proportional. Let's say this wasn't a dilation and AB over XY was 5 but AC over XZ was 4 that would mean it isn't proportional because AB would be 5 times bigger but XZ is only 4 times bigger.

Step-by-step explanation:
Min had some cards He gave half of the cards to Bill. Bill give 1/3 of those cards to Sam. Sam gave 2 cads back to Min and Kept 6. How many cards did Min have in the end?
Answer: 26 cards
Step-by-step explanation:
Suppose there are x cards initially
Min gave half to bill i.e. 0.5x
Bill gives one-third of those cards to Sam i.e. [tex]\frac{1}{3}\times 0.5x[/tex]
Sam gave 2 cards back to min and kept 6 i.e. Sam gets 8 cards from Bill
[tex]\Rightarrow 8=\dfrac{1}{3}\times 0.5x\\\\\Rightarrow 0.5x=24\\\Rightarrow x=48[/tex]
So, min has 0.5x+2 cards i.e.
[tex]\Rightarrow 0.5\times 48+2\\\Rightarrow 26\ \text{cards}[/tex]
