Answer:


Step-by-step explanation:

0.01x−0.3y=1;y=0.1x−2

Rewrite equations:

y=0.1x−2;0.01x−0.3y=1

Step: Solvey=0.1x−2for y:

y=0.1x−2

Step: Substitute0.1x−2foryin0.01x−0.3y=1:

0.01x−0.3y=1

0.01x−0.3(0.1x−2)=1

−0.02x+0.6=1(Simplify both sides of the equation)

−0.02x+0.6+−0.6=1+−0.6(Add -0.6 to both sides)

−0.02x=0.4

−0.02x

−0.02

=

0.4

−0.02

(Divide both sides by -0.02)

x=−20

Step: Substitute−20forxiny=0.1x−2:

y=0.1x−2

y=(0.1)(−20)−2

y=−4(Simplify both sides of the equation)

Answer:

x=−20 and y=−4

The answer is the temperature goes down 2.8° every hour and the expression is x=-11.2/4 because 4 is how many hours between 6pm and 10pm and its -11.2 because that was how much the temperature dropped from 6pm to 10pm

Answer: x= 2.5, y = 10

Step-by-step explanation:

<u><em>I'm going to assume that these photocopies are proportional in relations to each other.</em></u>

If they're proportional, you can set up two proportions:

1) \frac{x}{5} =\frac{3}{6} \\\\2) \frac{5}{y} =\frac{3}{6}

And cross-multiply:

1) 6x = 5*3 \\\\2) 3y = 5*6

Then solved for x and y:

1) 6x = 15\\x=\frac{15}{6} =\frac{5}{2} =2.5 \\\\2) 3y = 30\\y=\frac{30}{3} =10
