The price of a washing machine is reduced by 20% for a sale.
Afterwards, the sale price is increased by 30%.
Joachim says
The washing machine is now 10% more expensive than before the sale.
Explain Joachim’s error and work out the correct percentage change in the price of the washing machine from before the sale to after the sale
Answer:
1) Joachim's error is in applying the 30% increase to the initial price of the washing machine, 'x', rather than the reduced price of the washing machine for the sale, which is 0.8·x
2) The correct percentage change in price is 4%
Step-by-step explanation:
The price of the washing machine has the following parameters;
The percentage reduction of the price of the washing machine for a sale = 20%
The percentage by which the price is increased afterwards = 30%
Let 'x' represent the initial selling price of the washing machine before the price decrease, and let 'P' represent the sale price after the price increase, we have;
The price after the 20% reduction = x - 20% × x = x - (20/100) × x = 0.8·x
The price after the 30% increase after the sale = 0.8·x + 30% × 0.8·x = 0.8·x + 30/100 × 0.8×x = 0.8·x + 0.3 × 0.8·x = 1.04·x = x + 0.04·x = x + (4/100) × x = x + 4% × x
Therefore, Joachim's error is in applying the 30% increase to the initial price of the washing machine, 'x', rather than the reduced price of the washing machine for the sale, which is 0.8·x
2) The percentage change in the price after the sale is given as follows;
Price of the washing machine after the sale, P = 1.04·x = (104/100) × x = 104% × x
∴ P = 100%x + 4%x = (100/100)·x + 4%x = x + 4%
The percentage change in price = P - x = x + 4% - x = 4%
The correct percentage change in price = 4%

2x + 3 + 4x + 6 + 12x + 18 = 477
Please answer with solving steps. Thanks guys :)
Answer:
x= 25
Step-by-step explanation:
2x + 3 + 4x + 6 + 12x + 18 = 477
FIRST combine like terms
take all "x"
2+4+12= 18x
take all whole numbers
3+6+18= 27
18x+27= 477
now solve for x
-27 on both sides
18x= 450
÷18 on both sides
x= 25
yoi have to add the variables so 2x +4x+12x=18x and concombine like terms so 3 +6+18=27 so you have to put tbat together 18x+27=477 then you have to get x alone so you have to subtract 27 in both sides 27-27=0 then 477-27=450 then you have to do the oppsite of multiply so you have to divide 18x/18x and 450/18x 18÷18 is 1 so you just have to put x and then divide 450÷18=25 so x=25.

Answer:
See solution below
Step-by-step explanation:
Given the following expression
1) 24+r
If r = 9
24 + r = 24+9
= 33
2) 2a+3
If a = 10
Substitute
2(10)+3
= 20+3
= 23
3) BC+12.3
b = 9
c = 4
Substitute
= 9(4)+12.3
= 36+12.3
= 48.3
4) p÷q
Given p = 24 and q = 8
p÷q = 24÷8
p÷q = 3
5) 4c-7.8
If c = 4
Substitute
= 4(4)-7.8
= 16-7.8
= 8.2
6) c-a
a = 3
c = 17
Substitute
= 17-3
= 14
Hence c-a = 14
7) a ÷ 2c ; a = 20, c = 2
Substitute
a÷2c
= a/2c
= 20/2(2)
= 20/4
= 5
8) 3x-14
If x = 5
Substitute
= 3(5)-14
= 15-14
= 1
9) 1.5 + y² ; y = 6
Substitute
= 1.5+6²
= 1.5+36
= 37.5
10) t/5 + 6 ; t = 45
substitute the value of t given into the expression
= 45/5 + 6
= 9 + 6
= 15
A triangle has side lengths of 21 cm and 17 cm. What is the range of values possible for the 3rd side?
Answer:
[tex]4 < x < 38[/tex]
Step-by-step explanation:
[tex]21 - 17 = 4[/tex]
[tex]21 + 17 = 38[/tex]
The range of 3rd side is in between 4 to 38.
[tex]4 < side 3 < 38[/tex]
A triangle has side lengths of 21 cm and 17 cm
side 1 = 21 cm
side 2 = 17 cm
What is the relation between side of triangle?
The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Therefore,
length of side 3
[tex]21-17 < side 3 < 21+17[/tex]
[tex]4 < side 3 < 38[/tex]
Therefore the range of 3rd side is in between 4 to 38.
[tex]4 < side 3 < 38[/tex]

Find the area of a trapezoidal tabletop, if its parallel sides are 2 m and 3 m long and the perpendicular distance
between them is l m.
Answer:
The area of the trapezoidal table top is 2.5 m²
Step-by-step explanation:
The area, A, of a trapezoid is given as half times the sum of the parallel side multiplied by the perpendicular distance between them
Therefore, we have;
[tex]A = \dfrac{a + b}{2} \times h[/tex]
The given parameters of the trapezoidal table top are;
The length of the parallel sides = 2 m and 3 m
The length of the perpendicular distance between the parallel sides = 1 m
Where, for the rectangular table top, we have;
'a', and 'b' = The lengths of the parallel sides = 2 m and 3 m respectively
h = The perpendicular distance between the parallel sides = 1 m
By substituting in the values, we have;
[tex]A = \dfrac{2 \ m + 3 \ m}{2} \times 1 \ m = 2.5 \ m^2[/tex]
The area of the trapezoidal table top, A = 2.5 m².

-4.65< -4 and 2/5
Step-by-step explanation:
To solve, this we can convert the fraction -4 and 2/5 into a decimal so that the values can be more easily compared. When we do this, we get the result that -4 and 2/5 equals -4.4. Now we can clearly see which value is greater because they are written in the same form:
-4.65<-4.4
-4.65<-4 2/5
Answer:
<
