Which of the following ratio is the same 42 :14 in simplest form

Consider the graph shown for the Haunted Trail Ticket Prices. Which equation could you use to determine the total cost in dollar

Temka [501]

If you look closely at the graph 10 dollars are the price of 5 tickets and so we could use 2T = P as a expression and so if you plug 20 into T it would be 2(20)=P and it would become a evident 40=P as the answer (40)

An architect finds some unlabeled dimensions on a blueprint, and no scale is shown. A 14-foot wall that has already been built m

Marianna [84]

Answer:

Option (C)

The new wall will be 42 foot long

Explanation:

Given a 14-foot wall in reality equals 2 inches in drawing

And a new wall has to be built that measures 6 inches in the drawing

According to the question

2 inches (in drawing) = 14-foot (in reality)

6-inces (in drawing) = $\frac{(14\times6)}{2}$ = 42 foot

Therefore, the wall that measures 6 inches in the drawing will be 42 foot long in reality

Answer:

Cost of one candy = 80 L.L.

Step-by-step explanation:

Let "x" represent cost of a candy

Cost of 12 candies = 12x

Cost of a chocolate bar = 1,250 L.L.

Total cost = 2,210 L.L.

The following equation represents the scenario given:

1,250 + 12x = 2,210

Solve for x (cost of a candy)

1,250 + 12x - 1,250 = 2,210 - 1,250 (subtraction property of equality)

12x = 960

Divide both sides by 12

12x/12 = 960/12 (division property of equality)

x = 80

Cost of one candy = x = 80 L.L.

Which of these strategies would eliminate a variable in the system of equations?

mariarad [96]

Answer:

Multiply the bottom equation by -3/2 then add the equations.

Multiply the top equation by-3. then add the equations

Step-by-step explanation:

Given the simultaneous equation

2x- 6y=6 ... 1

6x - 4y = 2 ... 2

To eliminate a variable, we have to make the coefficient of one of the variable to be the same.

Multiply equastion 1 by -3

-6x+18y= -18

6x - 4y = 2

Add the result:

-6x + 6x + 18y-4y = -18+2

18y-4y = -18+2

14y = -18

y = -9/7

Another way is to Multiply the bottom equation by -3/2 then add the equations.

Multiplying equation 2 by -3/2 will give;

6x(-3/2) - 4y(-3/2) = 2(-3/2)

-9x + 6y = -3

Add to equation 1;

2x- 6y=6

-9x + 2x + 0 = -3+6

-7x = 3

x = -3/7

Hence the correct two options are;

Multiply the bottom equation by -3/2 then add the equations.

Multiply the top equation by-3. then add the equations

Can you help me answer this question

r-ruslan [8.4K]

Division of a fraction is the equivalent of multiplying by its reciprocal
ex.
$\frac{\frac{A}{B} }{\frac{C}{D}}=\frac{A}{B} *\frac{D}{C}$
i suggest you try to remember this concept

in terms of your question

$\frac{\frac{4c-12}{4c+8}}{\frac{c-3}{c^2-4}}= \frac{4c-12}{4c+8} *\frac{c^2 -4}{c-3}$

from this point, just multiple the numerators together and denominators together, then simplify if necessary

fyi- difference of squares
$x^2-b^2 = (x-b)(x+b)$
relating that to
$c^2-4 = c^2 -2^2 = (c-2)(c+2)$

also a side note, you might want to factor out the 4 first in the top fraction
