Answer:

x=1

Step-by-step explanation:

steps:

1: write the question question nicely.

2: the value outside multiply with the value inside but remember it should be separated by equal sign(=).(EXPAND).

3:Collect the like and unlike terms

4:remember - make x alone = ans.

so :write 6x/6=6/6

cancel 6 on both side and u will left with x onthe left side= and ans.

Answer:

$x = - \frac{19}{9}$

Step-by-step explanation:

5 - 2 (3x - 4) = 3 (x - 4) + 6

5 - 6x + 8 = 3x - 12 + 6

13 - 6x = 3x - 6

-6x - 3x = -6 - 13

-9x = 19 ÷ 9

x = 19/9

What is the sum of an 8-term geometric series if the first term is −11, the last term is 859,375, and the common ratio is −5? −1

LekaFEV [45]

Answer:

The sum of geometric series is 716144

Step-by-step explanation:

Given

First term=a_1= -11

Last term=a_8=859375

Common ration of geometric series=r= -5

And

Total terms in geometric sequence=n=8

We know that the formula for sum of geometric series is:

S_n= (a_1 (1-r^n))/(1-r)

= (-11(1-(-5)^8)/(1-(-5))

= (-11(1-5^8))/(1+5)

= (-11(1-390625))/6

=(-11(-390624)))/6

=4296864/6

=716144

So the sum of geometric series is: 716144 ..

The swimming pool at Spring Valley High School is a rectangle with a width of 65

tatiyna

Answer:

The area of the tiled floor is given by:

area = (190m)*w + 4*w^2

Step-by-step explanation:

Remember that the area of a rectangle of length L and width W is equal to:

A = W*L

For the case of the problem, we want to find the area of the tiled floor.

Then we need to find the difference between the area of the pool including the tiled floor and the area of the pool alone.

We know that the length of the tiled floor is w.

Then if the length of the pool is 30m, the length of the pool including the tiled floor is 30m + 2*w (because we have tiles in both sides)

And if the width of the pool is 65m, then the width of the pool including the tiled floor is 65m + 2*w

Now we want to find the difference between these areas, we have:

Area of the pool alone = 65m*30m = 1950m^2

Area of the pool including the tiles = (65m + 2*w)*(30m + 2*w)

The difference is:

D = (65m + 2*w)*(30m + 2*w) - 1950m^2

D = 65m*30m + 65m*2w + 30m*2w + 4*w^2 - 1950m^2

D = (65m + 30m)*2w + 4*w^2 + (65m*30m - 1950m^2)

D = 95m*2w + 4*w^2

D = (190m)*w + 4*w^2

This is the area of the tiled floor.

Mateo's sister Paid off her student loans $5000 in 30 years if she made a payment of $152.35 each month what was a simple intere

belka [17]

Answer:

3.23%.

Step-by-step explanation:

Please consider the complete question.

Mateo's sister Paid off her student loans $5000 in 3 years if she made a payment of $152.35 each month what was a simple interest rate for a way around it to the nearest hundred

Let us find total amount paid by Mateo's sister in 3 years.

1 year = 12 months

3 years = 12*3 months = 36 moths.

$\text{Amount paid in 36 months}=36\times \$152.35$

$\text{Amount paid in 36 months}=\$5484.6$

Now, we will use simple interest formula to solve our given problem.

$A=P(1+rt)$ , where,

A = Total amount after t years.

P = Principal amount,

r = Annual interest rate in decimal form,

$5484.6=5000(1+r(3))$

$\frac{5484.6}{5000}=\frac{5000(1+30r)}{5000}$

$1.09692=1+3r$

$1.09692-1=1-1+3r$

$3r=0.09692$

$r=\frac{0.09692}{3}$

$r=0.032306=3.2306\%\approx 3.23\%$

Therefore, the interest rate was 3.23%.
