The answer to the question above, the line of your triangle shows that it's divided proportionally.
So, the equation will look like this,
9( 3x + 2) = 12(4x - 2)

Then simplify the equation,
27x + 18 = 48x - 24

After that, transpose 48x to the left and 18 to the right.
27x+42 = 48x
Divide both sides by 21x
42 = 21x
21 21

so the answer will be 2

Find two numbers, if their sum is 49 and their difference is 1/2 .

amm1812

Answer:

$x=24\frac{3}{4}\\ y=24\frac{1}{4}$

Step-by-step explanation:

Let the two numbers be x and y

So we have:

$x +y = 49\\x-y=\frac{1}{2}$

using the elimination method, add the two equations together:

$2x=49\frac{1}{2} \\2x=\frac{99}{2}$

solve for x:

$x=\frac{99}{4}\\x=24\frac{3}{4}$

substitute our value for x back into the first equation we made:

$x+y=49\\(\frac{99}{4}) + y=49\\y=49-\frac{99}{4}\\y=\frac{97}{4} \\ y=24\frac{1}{4}$

therefore,

$x=24\frac{3}{4}\\ y=24\frac{1}{4}$

Step-by-step explanation:

Use the distributive property-

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

The line plot below shows the weight of each of 15 ostrich eggs . What is the total weight of the 3 heaviest eggs

erica [24]

Answer:

D). 6 3/4

Step-by-step explanation:

Given,

The three eggs with the heaviest weights are;

$2\frac{1}{2}$ ounces

$2\frac{1}{4}$ ounces, &

2 ounces

To find,

The total weight of the three heaviest eggs = $2\frac{1}{2}$ ounces + $2\frac{1}{4}$ ounces + 2 ounces

= 5/2 + 9/4 + 2/1

Taking the L.C.M. of 2, 4, and 1,

= 10/4 + 9/4 + 8/4

= (10 + 9 + 8)/4

= 27/4 or 6 3/4
