First you need to know the equation for inverse variation. y = k/x
Next, fill in the information you know so that you can find 'k', the constant of variation.
9 = k/3 Now solving for k we get k = 27 and you have your inverse equation for this problem and can use any values for intensity or resistance.
y = 27/x or I = 27/R
18 = 27/R
18R = 27
R = 27/18
R = 1.5 ohms

Match the equation with its graph 15x -12y=60
IgorLugansk [536]

Answer:

Check the attached graph for correct match.

Step-by-step explanation:

Graph of the given choices are not given but we can still solve this problem.

Given equation is  15x-12y=60.

Which is linear equation so we need at least two points to get the graph.

We are free to select any random number of x then plug that into given equation to find other variable.

Let's use x=0

15x-12y=60

15*0-12y=60

0-12y=60

-12y=60

divide both sides by -12

y=-5

Hence point is (0,-5)

Similarly plug y=0

15x-12y=60

15x-12*0=60

15x-0=60

15x=60

divide both sides by 15

x=4

Hence point is (4,0)

Now graph both points then join them by a straight line.

Any graph given in the choices which match with attached graph will be the answer.

Check the attached graph for correct match.

Solve the following equation
Ulleksa [173]

Answer:

n = 20

Step-by-step explanation:

n/2 - 9 = 1

Add 9 to each side

n/2 -9+9 = 1+9

n/2 = 10

Multiply by 2 on each side

n/2*2 = 10*2

n = 20

Irene has a checking account. On Monday she writes a $160 check for groceries. Then she deposits $125 into her account. Finally,
anastassius [24]
First you can see that there are 3 numbers 160,125,and 40 you can add 125 and 40 because they are both checks so then after you add you get $165 in checks do you then subtract $125 which is how much she put in and you get $40. So, she has $-40
In her bank account meaning her back scout was decreased by $40.

A pile of sand has a weight of 90kg.
Elodia [21]

Answer:

52.5 kg ANS

Step-by-step explanation:

Weight of a pile of sand = 90kg

Ratio of weight of sand in three bags = 2:3:7

Let the weight be 2x kg, 3x kg, 7x kg respectively A.T.Q.

= 2x + 3x +7x = 90

= 12x = 90

= X= 90/12

= X = 7.5 kg

Weight of sand in medium bag =

= 3 × 7.5

= 52.5 kg ANS

I hope this answer is correct
