Answer:

  6 for $37.50 has the same price

Step-by-step explanation:

The price per wand is found by dividing the price by the number of wands.

  8 for $50   ⇒   $50/8 = $6.25 per wand

__

  4 for $20   ⇒   $20/4 = $5.00 per wand   not the same

  6 for $37.50   ⇒   $37.50/6 = $6.25 per wand   is the same price

  10 for $65   ⇒   $65/10 = $6.50 per wand   not the same

Answer:

The equation of the line is y =  [tex]-\frac{4}{5}[/tex] x + [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

∵ A line passes through points (2, -1) and (-3, 3)

∴ x1 = 2 ad y1 = -1

∴ x2 = -3 and y2 = 3

→ Use the rule of the slope above to find the slope of the line

∵ m = [tex]\frac{3--1}{-3-2}[/tex] = [tex]\frac{3+1}{-5}[/tex] = [tex]\frac{4}{-5}[/tex]

∴ m = [tex]-\frac{4}{5}[/tex]

→ Substitute the value of m in the form of the equation above

∴ y =  [tex]-\frac{4}{5}[/tex] x + b

→ To find b substitute x and y in the equation by the coordinates of one  

   point of the given points

∵ x = 2 and y = -1

∴ -1 = [tex]-\frac{4}{5}[/tex] (2) + b

∴ -1 = [tex]-\frac{8}{5}[/tex] + b

→ Add [tex]\frac{8}{5}[/tex] t both sides

∵ -1 + [tex]\frac{8}{5}[/tex] = b

∴ [tex]\frac{3}{5}[/tex] = b

→ Substitute the value of b in the equation

∴ y = [tex]-\frac{4}{5}[/tex] x + [tex]\frac{3}{5}[/tex]

∴ The equation of the line is y =  [tex]-\frac{4}{5}[/tex] x + [tex]\frac{3}{5}[/tex]

Answer: 24.8 and 155.2

Step-by-step explanation:

x+x+130.4=180

2x=49.6

x=24.8

Answer:

155.2

Step-by-step explanation:

let x be the supplimentary angle

then the angle is

130.4+x

we have

130.4+x+x=180

2x=49.6

multiply both sides with 2

x=24.8

then the angle is

130.4+24.8

155.2

Answer:

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

Answer:

-3<x</2

Step-by-step explanation: the slash is the line.

Answer:

Step-by-step explanation:

(Sin27) / 11 = (sin x) / 15

cross multiply

15 sin27 = 11 sin x

keep in calculator as you divide 15sin27 by 11.

sin x = .6190779542

do sin ^ -1 (.6190779542) (It’s a key on the calculator.)

x = 38.25*

9514 1404 393

Answer:

  38.2°

Step-by-step explanation:

According to the equation you are give, ...

  sin(x)/15 = sin(27°)/11

Multiplying by 15 gives you ...

  sin(x) = 15·sin(27°)/11 ≈ 0.619078

The inverse sine function is used to find the angle x. It may show as sin⁻¹ on your calculator.

  x = arcsin(0.619078)

  x ≈ 38.2°

_____

Additional comment

x is shown in the figure as an acute angle, so that is the value we have chosen. The other angle that has sin(x) = 0.619078 is the supplement of this, or 141.8°. The two solutions are shown in the 2nd and 3rd attachments.

Answer:

the slope is 2

Step-by-step explanation:

the x's are increasing by 4 each time and the y's are increasing by 2 each time giving you [tex]\frac{4}{2\\}[/tex] which simplifys to 2

Answer:

12 weeks

Step-by-step explanation:

Make an inequality equation with x being the number of weeks:

200 > 500 - 25x

*subtract 500 from both sides*

-300 > -25x

*divide both sides by -25*

12 > x

Answer:

What she said

Step-by-step explanation:

Answer:

a=-39; s=0.75

Step-by-step explanation:

Solve the System of Equations by Substitution.

First, solve one of the equations for a variable. I'll do the 2nd one because it only has one variable.

a+24=-15 -------> a=-39

Now we know what a is just plug it back into the other equation and get s.

[tex]\frac{a-3}{7s} =-8[/tex]

[tex]\frac{-39-3}{7s} =-8[/tex]

[tex]\frac{-42}{7s} =-8[/tex]

Switch the -8 and 7s

[tex]\frac{-42}{-8} =7s[/tex]

Simplify the fraction

5.25=7s

Divide by 7 to isolate the s

0.75=s

Answer:

2)a+24=-15

a=-15-24

a=-39

Step-by-step explanation:

Answer:

C or D definitely not A or B bc it is too close of a number to 24.75 for 15

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

You want to find out how much it would be for 15 boxes

(5 , 11.25)

this is the first pair on the table multiply both by 3 because 5 x 3 = 15(boxes)

so we need to find how much it costs so now you multiply 11.25 by 3 which will be 33.75.
