nevsk [136]

Answer:Sample response: I set up an equation to show that the number of bracelets multiplied by the cost of each bracelet minus the commission is equal to the total, 6(x – 1.25) = 16.50. I divided each side by 6, then added 1.25 to each side with a result of x = 4. Hyo-Jim sold each bracelet for $4.

Find xif 4; 4+2×;4+4× are in Geometric sequences​
Ray Of Light [21]

Given:

4,4+2x,4+4x are in geometric sequences​.

To find:

The value of x.

Solution:

If a, b, c are in geometric sequences​, then

\dfrac{b}{a}=\dfrac{c}{b}

b^2=ac           ...(i)

It is given that 4,4+2x,4+4x are in geometric sequences​. By using (i), we get

(4+2x)^2=(4)(4+4x)

4^2+2(4)(2x)+(2x)^2=(4)(4)+4(4x)

16+16x+4x^2=16+16x

4x^2=16+16x-16-16x

On further simplification, we get

4x^2=0

x^2=0

x=0

Therefore, the value of x is 0.

PLEASE HELLLP!!!!! If x+7=2y and y=2x−1, what is the value of y? (NOT 13)
oee [108]

Answer:

(C) 5

Step-by-step explanation:

x+7=2y

<em>Subtract 7 from both sides</em>

x=2y-7

2y-7=x

<em>Multiply both sides by 2</em>

4y-14=2x

y=2x−1

<em>Add 1 to both sides</em>

y+1=2x

<u>Combine equations:</u>

y+1=4y-14

<em>Add 14 to both sides</em>

y+15=4y

<em>Subtract y from both sides</em>

15=3y

3y=15

<em>Divide both sides by 3</em>

y=5

<u>The answer is </u><u>(C) 5.</u>
