solve the solution of the equations 10x-3y=3 and 2x+y=9

Answers

Answer 1

Answer:

x=1.875   y=-0.875

Step-by-step explanation:

10x-3y=3                     10x-3y=3

3(2x+y)=(9)3                +6x+3y=27

                               1/16(16x)=(30)1/16  = x=1.875

   10x-3y=3                  10x-3y=3

 -5(2x+y)=(9)-5           -10x-5y=4                          

                                    1/-8(-8y)=(7)1/-8 = y=-0.875

The scale on a map indicates that 1 inch corresponds to an actual distance of 115 miles . Two cities are 7.5 inches apart on the map . What is the actual distance between the two cities?

Can someone please help me with this question I don’t understand it. Thank you

Answers

Answer:

it is 862.5

Step-by-step explanation:

each inch is 115 miles, so if theres two inches theres double the amount that there would be if there was 1 inch, so if theres 7 inches then you would have 7 times the amount it would be if there was 1 inch, in this situation theres 7.5 so you would multiply the 115 miles by 7.5 becuase that's how many inches there is, so multiplying that is the same as adding 115 plus 115 plus 115, and so on till you get the amount you need. did this help?

An employer's accountant has announced that
the budget for the next year must be cut by
33. How much must be cut from the
budget if last year's budget was
$166,245?
A. $11,830
B. $55,415
C. $166,245
D. $498,735

Answers

I think it is c forgive me I f I’m wrong

The amount of budget cut from last year's budget which was $166,245 will be $54860.85 which is nearly  $55,415 from the given option. Hence the correct option is (B).

What is the percentage?

The percentage is the 1 of the hundred or simply the amount or value of any number or data in the range of 100 called percentage.

For example, if Ramesh got 87 marks out of 150 then it required a lot of attention to drawing a conclusion about Ramesh's marks but if I say Ramesh got 58% then it will be easier to think and draw any conclusion.

Given that last year budget was $166,245 and the cut was 33% so it means it will be 0.33 of the $166,245 so

$166,245 × .33 = $54860.85 but in option, it is not mentioned so the nearest answer among the option will be (B).

A rectangular building with a square base is being designed to minimize heat loss. The building designers state that the volume of the building must be exactly 4000 m^3. Write an equation for y, the height of the building, in terms of x, the length and width of the base.

Answers

Answer:

y = 4000/x²

Step-by-step explanation:

The volume of the building is expressed as;

V = x²y where;

x is the length and width of the base.

y is the height of the building

Given

Volume V = 4000m³

Substitute the given volume into the equation as shown;

4000 = x²y

Make y the subject of the formula by dividing both sides by x²

4000/x² = x²y/x²

4000/x² = y

Rearrange

y = 4000/x²

Hence equation for y, the height of the building, in terms of x, the length and width of the base is expressed as y = 4000/x²

Solve the radical equation.
