7 L of paint is needed to cover 70m2. For 40m2, you can see that 4 L is needed, which means that for every 1 L, 10m2 can be covered. Multiply 1 L and 10m2 by 7, and you get 7 L is needed for 70m2.
We let C be the cost
x be the number of loaves
cost = overhead cost+ cost to bake - selling price
cost = 90 + 0.60x - 1.50x
cost = 90 - 0.90x
Hope this answers the question. Have a nice day. can you subscribe to my channel its flameboy21 valadez
Use distributive property:
16. 5k(3 - 4k)
15k - 20k^2
18. 6g^2(g - 8)
6g^3 - 48g^2
20. -2n^2 (5n - 9 + 4n^2)
-10n^3 + 18n^2 - 8n^4
Heya! This can be represented as a geometric number pattern. This is a number pattern which has a constant multiplier (in this case it doubles so the multiplier/ratio is 2). I’ve outlined a general formula for geometric/exponential number patterns where a is the first term, r is the ratio, and n is the term number. In this case, n is the amount of months the rabbits have been doubling for. The answer will be the y equation, where x is a positive natural number (i.e 1,2,3 etc. because we don’t have half months)
I'll assume you're asking for the initial price
Let's use x to represent it
The initial price plus 40 percent of that is $294
Let's write that out mathematically
x + (40/100)x = 294
x + 0.4x = 294
1.4x = 294
x = 210
The initial price is $210
