subtract

5x=0-(-25)

5x=25

x=25/5=5

-5-2y=-25

2ax - 15 = 3(x + 5) + 5(x - 1) In the equation above, a is a constant. If no value of x satisfies the equation, what is the value of a ?
NEED EXPLANATION!

Answers

Answer:

Step-by-step explanation:

Hello,

let s regroup the terms

2ax - 15 = 3(x + 5) + 5(x - 1) *** add 15 to both sides ***

<=> 2ax = 15 + 3x + 15 + 5x - 5 *** develop to remove the parentheses***

<=> 2ax = 8x + 25 *** simplify ***

<=> (2a-8)x = 25 *** subtract 8x from both sides ***

<=> (a-4)x=25/2 *** divide by 2 both sides ***

There is no solution is a-4 = 0 ,

because it would mean 0 = 25/2 and this is not possible

So it gives a = 4

Thanks

In the case when no value of x satisfies the equation so there the value of a should be 4.

Calculation of the value of a:

Since

the equation is

2ax - 15 = 3(x + 5) + 5(x - 1)

2ax = 15 + 3x + 15 + 5x - 5

2ax = 8x + 25

(2a-8)x = 25

So a = 4

hence, In the case when no value of x satisfies the equation so there the value of a should be 4.

Maurice's shirt has five buttons that are vertically arranged and equally spaced. His shirt is shown in the photo below. The first and last buttons are 15.25 inches apart when measured from the top of the first button to the top of the last button. What is the distance, in inches, between the top two buttons on his shirt, from the top of one to the top of the other? Round your answer to the nearest tenth.

Answers

Answer:

The distance between the top two buttons on his shirt is 3.8 inches.

Step-by-step explanation:

Maurice's shirt has 5 buttons. Distance between first and last button is 15.25.

If we see, they would be arranged like

They are equally spaced between each button.

So, there are 4 equal spaces between the buttons.

Distance between each two consecutive buttons =[tex]\frac{15.25}{4}[/tex] =3.8125

So, distance between the top two buttons on his shirt is 3.8 inches.

Gregoria borrowed $2,450, to be paid back at 3.5% simple interest. She repays $3221.75. How many years was the loan period?

Answers

Answer:

90.7yrs.

Step-by-step explanation:

Given parameters:

Amount borrowed = $2450

Interest rate = 3.5%

Amount repaid = $3221.75

Unknown:

Number of years the load was paid = ?

Solution:

The formula of simple interest;

I = PRT

Where I is the interest

P is the principal

R is the rate

T is the time

To find the interest;

Interest = Amount paid back - loan = 3221.75 - 2450 = 771.75

Now;

P = IRT

2450 = 771.75 x [tex]\frac{3.5}{100}[/tex] x T

2450 = [tex]\frac{2701.25T}{100}[/tex]

T = [tex]\frac{245000}{2701.125}[/tex] = 90.7yrs

The number of years of the loan period was 90.7yrs.
