Answer:
<em>x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 = 7(x + 1)</em>
Step-by-step explanation:
<u>Equations</u>
The situation can be written as an algebraic equation by setting the variables as follows:
x = first integer
x + 1 = second integer
x + 2 = third integer
x + 3 = fourth integer
x + 4 = fifth integer
x + 5 = sixth (and last) integer
The sum of all six numbers must be equal to 7 times the second number, thus:
x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 = 7(x + 1)
Answer:
Step-by-step explanation:
Find 3 ratios that are equivalent to the given ratio. 5/15
1 : 5 (0.2)
3/15 (0.2)
4 : 20 (0.2)
Density of water = 1000 kg/m^3
1 m^3 = 1000 litres
Therefore,
1000 kg/1000 l => 1 kg/l => 1000 g/l
Then, 300 g of water = 300/1000 l = 0.3 l
The concentration of the syrup = mass/amount of water = 60 g/0.3 l = 200 g/l
Use all the top to multiply by it
Then divide by the buttom.
P = g - 50
The profit in this equation, p, is similar to the y value and the g in this equation is equal to the x value. Because the profit per glass sold is one, you can just leave it out end up with g - 50 because you are deducting your profit from your expense.
