x1 = 12(20)/8

x1 = 30

a child find 29 nickels and dimes. how many dimes are there if the total value of the coins are $2.10?

DaniilM [7]

X represents nickels
y represents dimes
x+y=29
5x+10y=210
multiply the first equation by -5 (elimination method)
-5x-5y=-145
then add the two equations together
5y=65
divide 5 from both sides
y=13
13 dimes

54 divided by _____ = -27

Nikitich [7]

54/-2 = -27

First, let's rewrite:

Let x represent the unknown number:

$\frac{54}{x}=\text{ -27}$

$\begin{gathered} \frac{54}{x}\text{ = -27} \\ 54\text{ = -27x} \\ \text{Divide both sides by -27} \\ \frac{54}{-27}=\text{ }\frac{-27x}{-27} \end{gathered}$ $\begin{gathered} 27\times2\text{ = 54} \\ x\text{ = -2 (because we are dividing positive number by a negative number)} \\ So\text{ our answer will be negative} \end{gathered}$

Hence, 54/-2 = -27

There would be 2034 students competing in 2012.

We can write a simple equation to find this answer. Let X, be the number of students starting in 2012. Then, we multiply by 0.9 and 1.1 to get to 2014. To work backwards, just divide by 1.1, then by 0.9.

2014 / 1.1 / 0.9 = 2034
