Answer: the answer is 2x-3=15

Step-by-step explanation: It’s simple so whenever you see x in the equation you just plug 9 in it’s place for example:

equation 1: 2x-3=15 —> 2(9)=18-3= 15 for this equation 9 is the solution

equation 2: 4+5(9)=18 —> 4+45=49 and 49 does NOT equal to 18 therefor 9 is not a solution

equation 3: 3(9)+2= 29 and 29 does NOT equal to 25 so 9 is not the solution

equation 4: 81(9)-3=6 —> 726 does NOT equal to 6 so not a solution

equation 5: 24-2(9)=13–> 6 does not equal to 13 so 9 is not a solution

equation 6: 3(9)+7=8 —> 34 does not equal to 8 so 9 is not a solution

(hope this helps)

Answer:

$\displaystyle{ \frac{9}{16} \times \frac{2}{3} }$

$\displaystyle{ \frac{9 \times 2}{16 \times 3} }$

$\displaystyle{ \frac{18}{48} }$

$\displaystyle{ \frac{ \cancel2 \times \cancel3 \times 3}{2 \times \cancel2 \times 2 \times 2 \times \cancel3} }$

$\displaystyle{ \frac{3}{2 \times 2 \times 2} }$

$\displaystyle{ \frac{3}{8} }$

Out of a salary of $4500. I kept 1/3 as saving. Out of the remaining money. I spend 50% on food and 20% on house rent. How much

Step2247 [10]

Well 1/3 for savings means that you save 1/3*4500 or 1500 dollars.
You then have $3000 left. Of this if you spend 50% on food, you spend 0.5*3000 or 1500 dollars on food.

Which expression could represent the length of a rectangle that has an area equal to 4x2+12x?

grandymaker [24]

there are two expressions that can represent the length of the rectangle, these two expressions are:

L = x

L = (4x + 12)

<h3>Which expression could represent the length of the rectangle?</h3>

Remember that for a rectangle of length L and width W, the area is given by:

A = L*W

In this case, we know that the area is:

$A = 4x^2 + 12x$

We can factorize that expression into:

$A = x*(4x + 12)$

So there are two expressions that can represent the length of the rectangle, these two expressions are:

L = x

L = (4x + 12)
