If x varies inversely as y, and x=6 when y=72, find x when y=36

Mathematics
1 answer:
Hoochie [10]3 years ago
7 0

Answer:

12

Step-by-step explanation:

x = k/y           Multiply each side by y

k = xy            Insert values

  = 6 × 72

  = 432

x = 432/y     Let y = 36

  = 432/36

x = 12

Kaitlyn saves $6 each week. After correctly carrying out the Solve step of the five-step problem-solving plan, which solution sh
ch4aika [34]

Answer:

1. 10 weeks

Step-by-step explanation:

Apparently, we want to find the number of weeks (w) that Kaitlyn must save $6 in order to have a total of $60.

... $6 × w = $60

Divide by $6 to get ...

... w = $60/$6 = 10

Kaitlyn must save for 10 weeks (if she starts with a balance of 0).

_____

<em>Comment on the problem statement</em>

The problem reads like we came in somewhere in the middle of it. We don't know what other steps you've been asked to perform, or any of the details of the problem you're asked to solve. We don't have Kaitllyn's initial balance, for example, which is essential to determining how long she must save. (If Kaitlyn's initial balance is $33, for example, she must only save for 4.5 weeks.)

Convert the ratio 56: 80 to a percentage
zysi [14]
Change the ratio into a fraction

56:80  is the same as 56/80

Divide, make it a decimal

56/80 = 0.7

0.7 = 7/10 or 70/100

70/100 = 70%

70% is your answer

hope this helps

PLEASE HELP BRAINLIEST GIVEN TO CORRECT ANSWER

The solution to a system of (linear) equations is the point where the graphs intersect. Consider two parallel lines. By definition, two parallel lines never intersect each other, but all pairs of non-parallel lines will eventually intersect. That means they will also have a solution.

Let's consider what makes a line parallel to another line. It basically looks identical, having the same steepness (slope), but the graph is just shifted over. That is, a parallel line would have the same slope and a different y-intercept. For our equation 2y-4x=12, or y=2x+6 in slope-intercept form, a parallel line will be of the form y=2x+b.

That describes the form of a parallel line, which we do not want. Any other line, however, will give a solution to our system, so we merely want a line where the slope does not equal 2.

We can have any equation of the form y=mx+b, \ x \neq 2.

Franco and Marcia getting high speed Internet access at the same time. Francos provider charges $60 for installation and $42.95
In-s [12.5K]

Answer:

4 months

Step-by-step explanation:

Franco's provider = 60 + 42.95x

Marshal's provider = 57.95x

Where,

x = number of months

Equate both charges

Franco's provider = Marshal's provider

60 + 42.95x = 57.95x

Subtract 42.95x From both sides

60 + 42.95x - 42.95x = 57.95x - 42.95x

60 = 15x

Divide both sides by 15

60 / 15 = 15x / 15

4 = x

x = 4 Months

Franco and Marshal would have paid the same amount for high-speed Internet service after 4 months
