Answer:

C)   [tex] -1\frac{5}{8}x + 3 [/tex]

Step-by-step explanation:

[tex] \frac{1}{2}(\frac{3}{4}x + 10) - 2(x + 1) = [/tex]

[tex] = \frac{3}{8}x + 5 - 2x -2 [/tex]

[tex] = \frac{3}{8}x + 5 - \frac{16}{8}x - 2 [/tex]

[tex] = -\frac{13}{8}x + 3 [/tex]

[tex] = -1\frac{5}{8}x + 3 [/tex]

Answer:

  -8x -11

Step-by-step explanation:

Use the distributive property to eliminate parentheses. Then combine the constant terms.

  -4(2x +4) +5

  = -8x -16 +5

  = -8x -11

[tex]\sf \longmapsto-4 ( 2x+ 4) + 5[/tex]

[tex]\sf \longmapsto(−4)(2x)+(−4)(4)+5[/tex]

[tex]\sf \longmapsto−8x+−16+5[/tex]

[tex]\sf \longmapsto(−8x)+(−16+5)[/tex]

[tex]\sf \longmapsto−8x+−11[/tex]

[tex]\sf \longmapsto - 8x - 11[/tex]

Answer:

1,620,000 meters

Step-by-step explanation:

Speed-   450 meter----- 1 second

1 minute = 60 seconds

60 minutes (1 hour) = 3600 seconds

Distance in 1 hour

1 ------ 450

3600---- X

X= 3600 x 450

x= 1,620,000 meters

A plumber charges $65 to make a house call plus an additional charge of $42 per hour for labor. Write an equation to represent the total cost (y) for any number of hours (x).

Answer:

the required equation to represent the total cost with respect to every hour will be

=》y = 42x + 65

Step-by-step explanation:

total cost (y) = charge to make a house call + additional charge for every our

so, total additional charge for x hours

= 42 × x = 42x

hence y = 65 + 42x ( where 65 is charge to make a house call , y is total cost and 42x is additional charge for x hours )

The distance between points is √65.

The length of the line that connects two points is the distance between them. The distance can be determined by subtracting the coordinates that are not the same if the two points are on the same horizontal or vertical line.

The distance formula is used in analytic geometry to determine the distance between two lines, the sum of the lengths of all sides of a polygon, the perimeter of polygons on a coordinate plane, the area of polygons, and a variety of other measurements.

Given coordinates

R(5, 7) and S(-2, 3)

to find the distance between

the formula of distance for coordinates is

d = [tex]\sqrt{(y_{2} - y_{1} )^{2} + (x_{2} - x_{1} )^{2} }[/tex]

here y₂ = 3, y₁ = 7

x₂ = -2, x₁ = 5

substitute value in equation we get

d = [tex]\sqrt{({3 - 7 )^{2} + (-2 - 5 )^{2} }[/tex]

d = [tex]\sqrt{({-4 )^{2} + (-7 )^{2} }[/tex]

d = √(16 + 49)

d = √65

Hence the distance is √65.

Answer: Rounded: 350 miles/inch

Exactly 352 miles per inch.

Step-by-step explanation: Divide the miles by the inches to find miles per inch.

880/2.5 = 352.

It would make sense to round that to say the scale is 350 miles per inch.

One inch represents 350 miles

Answer:  15x + 25y = 4500

Step-by-step explanation:

The cost per general admission tickets is $15  and if x is used to represent the number of general admission tickets then 15 has to be multiplied by  x  and that gives the expression   15x  

The same with the VIP tickets, each one cost $25 and y is used to represent the number of VIP tickets sold, so if you want to find out how much a number of VIP tickets cost then you will have to multiply 25 by y  and that derives the expression  25y.

A combination of both tickets has to equal $4500 because that is amount they were both sold to get in total.

15x + 25y = 4500

37.5

Step-by-step explanation:

Answer:

6 is 16% of the number 37.5

Step-by-step explanation:

We have, 16% × x = 6

or, 16/100 × x = 6

Multiplying both sides by 100 and dividing both sides by 16,

we have x = 6 × 100/16

x = 37.5
