what is the sum (2/5x + 5/8) + (1/5x — 1/4)?

Answer:

75 feet²

Step-by-step explanation:

A scale drawing is the reduced image of another image

If the scale is 1 inch to 5 feet, it means that 1 inch presents 5 feet

If the area of the blueprint = 15 inches

It means the actual chicken coop would be 5 feet times larger than the blueprint

Actual area of the chicken coop = 15 inches² x 5 = 75 feet²

Answer:

[tex]x=-15.5[/tex]

Step-by-step explanation:

Write down what the problem is saying;

[tex]6(x+9)=2(x-4)[/tex]

Distribute;

[tex]6(x+9)=2(x-4)\\\\(6)(x)+(9)(6)=(2)(x)+(2)(-4)\\[/tex]

Simplify,

[tex]6x + 54 = 2x - 8[/tex]

Inverse operations,

[tex]6x + 54 = 2x - 8\\-2x\\\\4x + 54 = -8\\-54\\\\4x = - 62\\/4\\\\x =-15.5[/tex]

Answer:

Step-by-step explanation:

Given the value 141700000, we are to express in scientific notation

The standard form is expressed as A * 10^n

A is any integer between 1 and 10

n is also any integer

141700000.= 1.47 * 10^8

Note that the decimal point was shifted back 8 times, main reason the power is 8

Answer: 63360 inches per hour.

Step-by-step explanation:

9514 1404 393

Explanation:

A linear system of two equations in two variables will be a dependent system. This means both equations reduce to the same equation. The equations will be different only until they are reduced to the same form.

Here is one possible set of equations. The first is in slope-intercept form. The second is in point-slope form.

If we subtract the first equation from the second, we get ...

  (y -7) -(y) = (3(x -2)) -(3x +1)

  -7 = 3x -6 -3x -1 . . . . . eliminates y

  -7 = -7 . . . . . . . . . true for all values of x

There are an infinite number of solutions.

Answer:

120 children and 388 adults bought tickets for the swimming pool

Explanation:

Create two simultanous equations:

Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being

c

+

a

=

508

then, you now create a second equation for the prices of the tickets.

(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected

so:

1.75

c

+

2.25

a

=

1083.00

now we still know, that

a

=

508

−

c

so we can substitute it into the second formula

1.75

c

+

2.25

(

508

−

c

)

=

1083

now its just simple algebra

1.75

c

+

1143

−

2.25

c

=

1083

60

=

0.5

c

so:

c

=

120

now we know, that 120 children went to the swimming pool.

and we still have the formula from before:

a

=

508

−

c

so

a

=

388

Step-by-step explanation:

My teacher just told me

Answer:

62

Step-by-step explanation:

60 + 58 + y = 180

118 + y = 180

y = 180 - 118

y = 62

Answer:

Yes, it is possible

Step-by-step explanation:

It is possible because X does on the second day could be negative. It's a simple question, and you don't need to figure out the answer.

Basically, X on the second day could be a negative OR positive answer.
