So hmm let's say

t = number of movie tickets purchased
m = number of meals bought

so... he earns 0.5 for each ticket... so if he bought "t" tickets, he then earned 0.5*t or 0.5t , whatever that is

and if he bought "m" meals, since each one is $2 earnings, then he earned 2 * m or 2m, whatever that is

is just so happen, we know, for last month he earned on his rebates $25
thus

0.5t + 2m = 25

it just so happen we also know he bought 22 movie tickets last month
thus

$\bf 0.5(22) + 2m = 25\implies 11+2m=25\implies 2m=25-11
\\\\\\
2m=14\implies m=\cfrac{14}{2}\implies \boxed{m=7}$

<span>It would be 0.5x + 2y = 22</span>

Y= -x +3 and y = x - 1

Answer:

x=2 and y=1

Step-by-step explanation:

Rewrite equations:

y=−x+3;y=x−1

Step: Solve

y=−x+3

Step: Substitute−x+3foryiny=x−1:

y=x−1

−x+3=x−1

−x+3+−x=x−1+−x(Add -x to both sides)

−2x+3=−1

−2x+3+−3=−1+−3(Add -3 to both sides)

−2x=−4−2x−2=−4−2

(Divide both sides by -2)

x=2

Step: Substitute2forxiny=−x+3:

y=−x+3

y=−2+3

y=1(Simplify both sides of the equation)

Hope this Helps you :)

What does product rule of exponents say

LuckyWell [14K]

The rules of exponents are
$( x^{m})( x^{n})=( x^{m+n})$
$\frac{ x^{m} }{ x^{n} } = x^{m-n}$
$x^{ \frac{m}{n} } = \sqrt[n]{ x^{m} }$
$( x^{m} )( y^{m} )=(yx)^{m}$
$( x^{m})^{n}=x^{mn}$
$( \frac{x}{y})^{m}= \frac{x^{m}}{y^{m}}$
$x^{-n}= \frac{1}{x^{n}}$
these are just some basic ones
