445 + 210 + 525 = 1,180
500 + 85x = 1,180
-500 -500
85x = 680
/85 /85
x = 8
Answers:
<h3>1. -5</h3><h3>2. 7</h3><h3>3. 1</h3><h3>4. 5</h3>
Step-by-step explanation:
Plug in the x into the equation and solve.
<h3>Value 1: X = 5</h3>
Y = -2(5) + 5
Y = -10 + 5
Y = -5
<h3>Value 2: X = -1</h3>
Y = -2(-1) + 5
Y = 2 + 5
Y = 7
<h3>Value 3: X = 2</h3>
Y = -2(2) + 5
Y = -4 + 5
Y = 1
<h3>Value 4: X = 0</h3>
Y = -2(0) + 5
Y = 0 + 5
Y = 5

Answer:
540
Step-by-step explanation:
1. We assume, that the number 900 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 900 is 100%, so we can write it down as 900=100%.
4. We know, that x is 3.5% of the output value, so we can write it down as x=3.5%.
5. Now we have two simple equations:
1) 900=100%
2) x=3.5%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
900/x=100%/3.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 3.5% of 900
900/x=100/3.5
(900/x)*x=(100/3.5)*x - we multiply both sides of the equation by x
900=28.571428571429*x - we divide both sides of the equation by (28.571428571429) to get x
900/28.571428571429=x
31.5=x
x=31.5
now we have:
3.5% of 900=31.5
Answer:
Option C is correct.
Step-by-step explanation:
In an inverse variation, an increase in one quantity leads to a corresponding decrease in the other.
The product is constant throughout the table.
The product is 
and it shows inverse variation also.
