The value of X is 12. STEP 1) distribute the 1.50 to the X and 6 to get 1.50x and 9 STEP 2) subtract 9 from 27 to get 18 STEP 3) divide 18 by 1.5 and you get X=12

X=12 because
1.5x+9=27
27-9=18
18 divided by 1.5 is 12. !!!!

5x(6x+28)=-23 <br><br>Help I don't understand

aksik [14]

Answer:

Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.

Exact Form:

x = − 70 ± √4210/30

Decimal Form:

x = −0.03

Step-by-step explanation:

5x(6x+28)=−23

Step 1: Simplify both sides of the equation.

30x2+140x=−23

Step 2: Subtract -23 from both sides.

30x2+140x−(−23)=−23−(−23)

30x2+140x+23=0

Step 3: Use quadratic formula with a=30, b=140, c=23.

x=−b±√b2−4ac/2a

x=−(140)±√(140)2−4(30)(23)/2(30)

x=−140±√16840/60

x=−7/3+1/30√4210 or x=−7/3+−1/30√4210

You are given a choice of taking the simple interest on $10,000 invested for 2 years at a rate of 3% or the interest on $100,

attashe74 [19]

Answer:

Compount interest earns more. Difference between 2 interest is $92 445.39

Step-by-step explanation:

Simple Interest:

$I = \frac{prt}{100}$

p = $10000

r = 3%

t = 2years

I = (10000×3×2)/100

= $600

Total amount = $10 600

Compound Interest:

$A = p( {1 + \frac{r}{100}) }^{n}$

p = $100000

r = 3/730 (daily)

t = 730 (2yrs)

A = 100000[1+(3/73000)]^730

= $103 045.39 (2d.p)

Difference = $103045.39 -

$10600

= $92 445.39

(Correct me if i am wrong)

What is the base area of a cylinder with a radius of 2

Alex17521 [72]

Answer:

(pi)4 or about 12.57 sq. units

Step-by-step explanation:

The base area of a cylinder is a circle.

Since we know that the radius is 2, we can use the equation A = (pi)r^2 to find the area.

So, using this formula, the area is (2)(2)(pi), about 12.57 sq. units (area is squared!)

Marie is cleaning her clothes out of the closet in her spare bedroom. She started with 650 of her items in the closet. She has b

Lemur [1.5K]

Wording is everything. Here, there are some issues. "... at the rate of 1/2 per month" can be interpreted to mean that at the end of the first month, there are 649 1/2 items in Marie's closet (decreased by 1/2 from 650).

"The number of items Dustin adds" could mean 5 items, the number he adds each month. The wording should specify the time period or whether we're talking about the total number Dustin has added.

We assume your description means that the number of items in Marie's closet at the end of each month is 1/2 what it was at the beginning. (As opposed to decreasing by 1/2 item each month.) We assume we're interested in the total number of items of Dustin's that are in the closet.

Marie's quantity can be modeled by ...

... m = 650·(1/2)^t . . . . . t = time in months

Dustin's quantity can be modeled by ...

... d = 5t

There will be one solution for d=m, at about t = 4.8. At that point, Dustin will have added about 24 items, which will be the number Marie is down to.

There is a viable solution for d=m at about t = 4.8.
