Answer:  ruler cost $12

Step-by-step explanation:

step 1

Let cost of ruler  be represented as r

and cost of pencil be represented as p

we were given that

4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils which is expressed as

4r + p = 2r+ 4p

and cost of pencil= $8

therefore

sTEP 2--- Solving

4r+ 8 = 2r+ 4 x8

4r+ 8 = 2r+ 32

4r - 2r= 32-8

2r= 24

r= 24/2 = r= $12

Answer:

([tex]\frac{18}{5}[/tex], [tex]\frac{16}{5}[/tex] )

Step-by-step explanation:

Given the 2 equations

y = 2x - 4 → (1)

x + 2y = 10 → (2)

Substitute y = 2x - 4 into (2)

x + 2(2x - 4) = 10 ← distribute and simplify left side

x + 4x - 8 = 10

5x - 8 = 10 ( add 8 to both sides )

5x = 18 ( divide both sides by 5 )

x = [tex]\frac{18}{5}[/tex]

Substitute this value into (1) for corresponding value of y

y = 2([tex]\frac{18}{5}[/tex] ) - 4 = [tex]\frac{36}{5}[/tex] - [tex]\frac{20}{5}[/tex] = [tex]\frac{16}{5}[/tex]

solution is ([tex]\frac{18}{5}[/tex], [tex]\frac{16}{5}[/tex] )

Answer:

105

Step-by-step explanation:

if you cross multiply 1 [tex]\frac{7}{8}[/tex] and [tex]\frac{x}{56}[/tex] you get [tex]\frac{840}{8}[/tex] which is 105  

Answer:

Not apportionment

Step-by-step explanation:

Apportionment can be described as a way of sharing out or dividing out in the best fair method.

If a family of 10 leave the house at the same time and have to share just two bathrooms, the time allocation should not be based on age rather should be based on how early each person wakes up in the morning.

Answer:

[tex]0< b\leq 14.5[/tex]

Step-by-step explanation:

Let's set up our equation. We know that rectangles have two pairs of equal sides. We are also given that one pair of those sides is 1 unit longer than the other pair. Finally, we are told that the perimeter is at most 60 meters. 'At most' tells me to set up an inequality.

I'm going to set up two equations to solve this problem. First, let [tex]a[/tex] be the longer side and [tex]b[/tex] be the shorter side.

[tex]2a+2b\leq 60[/tex]

Next, because the sides are consecutive integers and [tex]b[/tex] is shorter, we can say that [tex]a-b=1[/tex].

We now have a system of equations. I will solve using substitution.

[tex]a-b=1\\a=b+1[/tex]

Substitute [tex]a[/tex] into the first equation.

[tex]2(b+1)+2b\leq 60[/tex]

Solve algebraically.

[tex]2b+2+2b\leq 60\\4b+2\leq 60\\4b\leq 58\\b\leq 14.5[/tex]

So, [tex]b[/tex] could be any integer between 0 (since distance cannot be negative) and 14.5, also written as [tex]0<b\leq 14.5[/tex].

I hope this helped!

Answer:

105 cm²

Step-by-step explanation:

The shape is composed of a rectangle and a triangle on the right side

area of rectangle = 15 × 6 = 90 cm²

The triangle has dimensions , base = (15 - 9) = 6 cm and height = (11 - 6) = 5 cm

area of triangle = [tex]\frac{1}{2}[/tex] × 6 × 5 = 3 × 5 = 15 cm²

Total area = 90 + 15 = 105 cm²

Answer:

Reflect over x-axis. Then translate up 5 units.

Answer:

multiply both expressions

(8x - 2)(4)

32x - 8

simplify

32x = 8 4 ( 2 2 2 2 2 2)

-8 = 8 -1

8(4x - 1)

Step-by-step explanation:

Answer:Ten dollars per hour

Step-by-step explanation:

50 hour =500 dollars

1 hour = ?

Using the criss cross method we multiply one hour by five hundred dollars and divide by fifty dollars.

?=(1 hour×500 dollars)/50 hour

?= 500 dollars/50

?=10 dollars per hour

Answer:

$10

Step-by-step explanation:

$500/50= 10

He needs to earn $10 an hour x the 50 hours = $500

Answer:

7[tex]\sqrt{3}[/tex]

Step-by-step explanation:

the altitude creates two congruent 30-60-90° triangles

the ratio of the sides in a 30-60-90°, respectively, are 1 : [tex]\sqrt{3}[/tex] : 2

therefore we can set up a proportion to find the side length:

let 'x' = side length of equilateral Δ

[tex]\sqrt{3}[/tex] / 1 = 21 / x

cross-multiply:

[tex]\sqrt{3}[/tex]x = 21

x = 21 / [tex]\sqrt{3}[/tex]

rationalize the denominator by multiplying numerator and denominator by [tex]\sqrt{3}[/tex]

21[tex]\sqrt{3}[/tex] / [tex]\sqrt{3}[/tex]·[tex]\sqrt{3}[/tex] = 21[tex]\sqrt{3}[/tex] / 3 or 7[tex]\sqrt{3}[/tex]

Answer:

[tex]x \geq 6[/tex]

Step-by-step explanation:

You can start by dividing both sides by 2, getting [tex]x \geq 6[/tex].

Answer:

randomly choosing a marble from a bag, replacing it, and choosing again

rolling a number cube, rolling again, and trying to match the first roll

Explanation:

In an independent event, getting a certain outcome once does not change the probability of getting the same outcome again.

The second option (about the coins) is NOT independent because if you pull out a dime on your first try, there are fewer dimes in your pocket and you are less likely to pull out a dime the second try. The third option (about drawing a number) is also NOT independent for the same reason: you don't put the number back into the hat after drawing it out, so there's fewer numbers the second time and the probability is different.

Answer:

Step-by-step explanation:

You are trying to find the values of two quantities, so you will need to set up a system of two equations in two variables. We'll call M the price of a movie and V the price of a video game.

The first month: 3 movies, 8 video games, $55. Let's translate this into algebra:

3M + 8V = 55

The second month: 5 movies, 2 video games, $18. Translated:

5M + 2V = 18

Solve that system of equations

Answer:

Answer:

Angle P = 143º

Angle Q = 37º

Step-by-step explanation:

Linear pair means the angles add up to 180º

So, using this, set up the equation: 7x - 4 + 2x - 5 = 180

Combine Like Terms

9x - 9 = 180

Add on both sides

9x = 189

Divide

189/9 = 21

Substitute 21 for x

Angle P: 7(21) - 4

Angle Q: 2(21) - 5

Answer:

x = 55

Step-by-step explanation:

Here, we want to get the value of x

From the diagram , we can see that we have a right- triangle

and thus,

x + 35 = 90

x = 90-35

x = 55

Answer:

625 tiles

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Total room floor area = 16 × 12 = 192

So, area of one third room = 192 × (1 ÷ 3)

Area of one third room = 64

Length of each tiles = 0.32

As it is a square tile, width = length, = 0.32

o, total area of each tile = 0.32 × 0.32 = 0.1024

So, number of tiles to cover 64 area of room = 64 ÷ 0.1024 = 625 tiles.

Hence, 625 tiles needed to cover one third of room.
