solve for x. √(x+3)=2√(x-1)​

Answer: $ 19.44

Step-by-step explanation:

Give : Original price of coloring book = $18

Sales tax = 8% =0.08 [we divide number by 100 to remove %]

Now , the final price of the Anime coloring book = Original price + (Original price) x (Sales tax)

=$ ( 18+18 x 0.08)

= $ (18)(1+0.08)

= $ (18)(1.08)

= $ 19.44

Hence, the final price of the Anime coloring book = $ 19.44

Answer:

If you have have 24 coins and 7 pouches, you can put 3.43 coins in each pouch.

Step-by-step explanation:

To solve this you want to divide the 24 coins into 7 pouches.

x = coins

y = pouches

z = how many coins can go in each pouch:

[tex]x/y = z[/tex]

Substitute:

24/7 = z

3.42857142857 = z

round to the nearest hundredth:

3.43 = z

If you have have 24 coins and 7 pouches, you can put 3.43 coins in each pouch.

To figure out how many coins go into each pouch, divide the number of coins by the number of pouches.

Coins per pouch = 24/7 = approx. 3.43

Answer:

Credit card B is a better deal

Step-by-step explanation:

in order to compare both credit cards, we must either convert the APR into a monthly rate or the monthly rate to APR.

convert credit card A's APR to monthly rate:

= 22.45% / 12 ≈ 1.87%, which is higher than 1.25%, so credit card B is better

OR

convert credit card B's monthly rate to APR:

= 1.25% x 12 = 15%, which is lower than 22.45%, so credit card B is better

Answer:

-9x+5y=-4

Step-by-step explanation:

Answer:

m= 9/5

Step-by-step explanation:

Parallel lines have the same slope.

So if you can find the slope of the given line, you have the slope you want.

Change the line into the form

y=mx + c

The value of m

will be the slope of the line.

9x −4 = 5y ← to make the y term positive

y=9/5x − 4/5

m=9/5

Answer:

Answer: Around 1000 students would buy a school lunch.

Step-by-step explanation:

We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.

In total we have 20 + 14 = 34 students, this will be our 100%.

The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.

p1 = (14/34)*100% = 41.18%

And the percentage of students that buy lunch at school can be computed in the same way:

p2= (20/34)*100% = 58.82%

Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.

Then the exact number will be:

N = (58.82%/100%)*1700 = 1000

Around 1000 students would buy a school lunch.

Answer: I think the answer is 32 bacteria after 40 minutes.

Step-by-step explanation:

I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

Step-by-step explanation:

Answer:

To find slop from the given equation,

Slope (m) =

[tex] \frac{ - \: cofficients \: of \: x }{cofficient \: of \: y} [/tex]

So, slope of this equation is - 2

For perpendicular case,

M1 . M2 = - 1

Thus, m2 = 2 ( for this equation)

Similarly,

For parallel case,

M1 = m2

Thus, m2 = - 2 ( for this equation)

Answer:

46

Step-by-step explanation:

6 times 2 is 12

23 times 2 is 46

Answer:

B = 46

given the equation, you can multiply 6 by 2 to get 12, so when you multiply 23 by 2 you get 46.

Answer:

$14.00 per pound for A and $12.50 per pound for B and B is offering the better one since it has a lower cost per pound

Step-by-step explanation:

Answer:

Brand A is $14

Brand B is $12.5

Brand B is offering the better value. I know this because when you get the unit rate for Brand A it is $14. When you get the unit rate for Brand B you get $12.5. So You pay less money for Brand B then Brand A.

Step-by-step explanation:

For brand A you need to first divide 70 by 5 which equals to 14

Then you divide 105 by 12 which equals 12.5

Answer: See explanation

Step-by-step explanation:

Your question isn't really clear. Let me help you rephrase it and solve.

Let's say Cesar is creating a schedule to practice his instrument for band. He needs to practice for a total of 10 hours in a week. On Monday he practice for 1 1/2 hours, on Tuesday he practiced for 2 1/4 hours, and on Wednesday he practiced for 1 1/2 hours.

The total hours that Cesar has used in practicing will be:

= 1 1/2 + 2 1/4 + 1 1/2

= 5 1/4

To get the number of hours that Cesar need to practice during the rest of the week in order to have his 10 total hours, we subtract 5 1/4 hours from 10 hours. This will be:

= 10 - 5 1/4

= 4 3/4 hours.

Cesar needs to practice for 4 3/4 hours more.

Answer:

length is 17 in, width is 20

Step-by-step explanation:

let's shape this as an algebraic equation, where x= the length of one side.

since the width is 3 inches longer than the length, x will be the length and x+3 will be the width.

the perimeter is 74 in, and the perimeter is the added length of all sides. in a rectangle, 2 sides are the length and 2 sides are the width, so:

74 = 2x + 2(x + 3)

let's distribute the 2.

74 = 2x + 2x + 6

now, we combine the x's.

74 = 4x + 6

after this step, subtract 6 from the right to add it to the left side.

68 = 4x

finally, divide both sides by 4.

17 = x

perfect! now that we know the length, we just have to add 3 to find the width.

17 + 3 = 20

Answer:

see explanation

Step-by-step explanation:

Given

- 9 < x - 3 < 1 ( add 3 to each interval )

- 6 < x < 4

Thus integer values which satisfy the inequality are

x = - 5, - 4, - 3, - 2, - 1, 0, 1, 2, 3
