X - the number

$80\%x=12 \\
\frac{80}{100}x=12 \\
\frac{4}{5}x=12 \\
x=12 \times \frac{5}{4} \\
x=3 \times 5 \\
x=15$

12 is 80% of 15.

(1 2/7-3/14)/8/15trying to remember how to do this

SOVA2 [1]

We will write it as a fraction in ordet to solve, that is:

$\frac{(1\frac{2}{7}-\frac{3}{14})}{(\frac{8}{15})}$

We then operate as follows:

$\frac{((\frac{7}{7}+\frac{2}{7})-\frac{3}{14})}{(\frac{8}{15})}\Rightarrow\frac{(\frac{9}{7}-\frac{3}{14})}{(\frac{8}{15})}\Rightarrow\frac{(\frac{15}{14})}{(\frac{8}{15})}\Rightarrow\frac{15\cdot15}{14\cdot8}\Rightarrow\frac{225}{112}$

We have this, since 1 integer will be equal as a numerator divided by a denominator with equal values. Examples 1 = 2/2, 1 = 45/45, ...

jonny [76]

Answer:

18.6 months

Step-by-step explanation:

Given that :

Best fit line from scatterplot :

y=-12.05x +224.26

x = Number of month

y = charge on battery

Number of months a typical battery uses before being dead completely :

When battery is dead completely ; charge =0, y = 0

y = -12.05x + 224.26

0 = - 12.05x + 224.26

12.05x = 224.26

x = 224.26 / 12.05

x = 18.610788

Hence, 18.6 months before battery is completely dead.
