15% as a decimal is 0.15
Our regular cost of chocolates is 1.0
New cost is 1.0 + 0.15 = 1.15
1.15 x 17.25 = 19.8375
In the states we round to the hundredth for cost, so it would be £19.84
Alternate method: calculate 0.15 of 17.25 and add that to 17.25
0.15 x 17.25 = 2.5875
17.25 + 2.5875 = 19.8375
<u>Answer:</u> $12.60
<u>Explanation</u>:
An alternate and easier way of finding the clearance price of an item is to take the percentage off and subtract it from 100. This way you don’t have to subtract your product from the total price to find your answer. This’ll make more sense when I show both methods.
Method #1 (harder):
Original price: $18
30% discount
Make the percentage a decimal and multiply it by the original price.
18 x .3 = 5.4 or $5.40
Original price - 5.4 = 12.6 or $12.60
Method #2 (short cut, one less step):
100% - 30% = 70%
Think about it like this - the 30% is what you’re NOT paying for while the 70% is what the item will actually be worth.
Original price x .7 = 12.6
Subtract 4x from both sides
4x +2 = 7x - 13 would then simplify to
3x - 13 = 2 ( you can switch the problem around as long as you dont switch the variables around )
then you have to + 13 which simplifies to
3x = 15
then you divide by 3 which equals
x=5
Answer:
Third answer shown
Step-by-step explanation:
Since each equation has a right side equal to the same thing, y, those right sides must be equal to each other.
x + 3 = -2x + 6
Add 2x to both sides. 2x 2x
3x + 3 = 0 + 6
3x + 3 = 6
Subtract 3 on both sides. -3 -3
3x = 3
Divide both sides by 3. x = 1
Now, let's see what y must be if x equals 1.
Line M: y = x + 3 --> y = 1 + 3 --> y = 4
Line N: y = -2x +6 --> y = -2(1) +6 --> y = -2 + 6 --> y = 4, confirmed
So the ordered pair (x, y) that satisfies <u><em>both </em></u>equations is (1, 4)
*** This means that if you graphed both lines on an xy-coordinate plane, the point (1,4) would be the point where the two lines intersect.
That is the third answer shown.
Answer:
Step-by-step explanation:
In exponential multiplication, if bases are same, add the powers
xᵃ * xᵇ = xᵃ⁺ᵇ
Side = 12d⁶e⁷
Area of square = side *side
= 12d⁶e⁷ * 12d⁶e⁷
= 12* 12* d⁶e⁷ * d⁶e⁷
= 144d⁶⁺⁶ * e⁷⁺⁷
= 144d¹²e¹⁴
