Find the value of X on this proportion

2 answers:

5 0

solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation. You'll probably start out by just solving proportions, like this:

Find the unknown value in the proportion: 2 : x = 3 : 9.2 : x = 3 : 9First, I convert the colon-based odds-notation ratios to fractional form:.Then I solve the proportion:
9(2) = x(3) 
18 = 3x
6 = xFind the unknown value in the proportion: (2x + 1) : 2 = (x + 2) : 5(2x + 1) : 2 = (x + 2) : 5 ADVERTISEMENT First, I convert the colon-based odds-notation ratios to fractional form:Then I solve the proportion:
5(2x + 1) = 2(x + 2)
10x + 5 = 2x + 4
8x = –1
x = –1/8

Answer:

AJ picks 252 pounds

Step-by-step explanation:

Lets define the following letters for each name:

A is AJ

B is Blaze

L is Laurence

J is Jack

Now we will analyze the phrases one by one:

Blaze picks three times as many as Laurence means:

$B = 3 * L$

Jack picks twice as many as Blaze.

$J = 2 * B$ , ans using the previous one lets substitute B with 3 * L

$J = 2 * B = 2 * (3 * L)$

$J = 6 * L$

Aj picks three times as many as Laurence.

$A = 3 * L$

The total weight of the oranges is 1092 pounds.

$A + B + J + L = 1092$

We replace A, B & J in the last equation, with the previous results:

$A + B + J + L = 1092$

$(3*L) + (3*L) + (6*L) + L = 1092$ , grouping using L as common factor:

$(3+3+6+1) * L = 1092$

$13 * L = 1092$ , then isolating L:

$L = 1092 / 13$

$L = 84$ pounds (for Laurence)

Finally replacing L in the previous equations:

$A = 3 * L = 3 * 84 = 252$ pounds (for Aj)

$B = 3 * L = 3 * 84 = 252$ pounds (for Blaze)

$J = 6 * L = 6 * 84 = 504$ pounds (for Jack)

The correct option regarding whether the table represents a proportional relationship is:

The relationship is proportional because the ratio of m to k is constant.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

In this problem, the ratio of m to km is given as follows:

k = 11/17.699 = 26/41.834 = 34/54.706 = 0.6215.

Since the values are equal, the correct option is:

The relationship is proportional because the ratio of m to k is constant.
