Answer:

White roses - 7

Red roses - 17

Step-by-step explanation:

Set up proportional equations

White roses = x

Red roses = 3x - 4

Set equal to 24

x + 3x - 4 = 24

4x - 4 = 24

4x = 28

x = 7

x is white roses, so there are 7

Plug x value into red rose equation

3(7)-4

21-4 = 17 red roses

Check

17+7 = 24

Answer:

what is the question...?

Step-by-step explanation:

The percentage change from $300 to $1,100 is 266.67% increase

How?

1,100 - 300 ÷ 300 = 2.6667

2.6667 x 100 = 266.67%

^this is how you find the percent in change

(You could have just asked me to show my work instead of reporting me- that was a bit uncalled for)

Answer: $266.667% change

Step-by-step explanation:

(V2 - V3) (1100 - 300) 800

_______ x100 = ________ x 100 = ____ x 100= $2.66667% = $266.667%

V1 300 300 x 100 increase or change

Answer:

x = { - 2, 2 }

Step-by-step explanation:

Given

6x² - 24 = 0 ( add 24 to both sides )

6x² = 24 ( divide both sides by 6 )

x² = 4 ( take the square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2

solution set is { - 2, 2 }

Answer:

the required answers are :

a) x = 4

b) x = 3

c) a = 7

d) x = -15

Answer:

1/16

When you calculate they both get the answer 0.0625

Step-by-step explanation:

let the unknown number be x

6 * x * 3 = 90

18 x = 90

x = 90/ 18

x = 5

Hope it will help :)

Answer: 5

Step-by-step explanation:

30 divided by 6 is 5, so 6 x 5 x 3=90

Answer:

$3.25

Step-by-step explanation:

An item is regularly priced at $65. Abdul bought it at a discount of 95% off the regular price. Use the ALEKS calculator to find how much Abdul paid.​

Original price of item = $65

percent discount = 95%

discount price = 95% * 65

discount price = 0.95 * 65

discount price= $61.75

Amount abdul paid = Original price - discounted price

Amount abdul paid = $65 - $61.75

Amount abdul paid = $3.25

Hence abdul paid $3.25

Answer:

392x−3136

Step-by-step explanation:

Given that,

An estimate of the height, H metres, of a tall building can be found  using the formula :

H = 3f + 15

where the building is f floors high.

f = 85

The real height of the building is 260 m.

To find,

The percentage error.

Solution,

We have,

H = 3f + 15

Put f = 85 in the above formula

H = 3(85) + 15

H = 270 m

Error,

[tex]E=\dfrac{270-260}{260}\times 100\\\\=3.84\%[/tex]

So, the required error is 3.84%.

Answer:

Percent increase = 25%

Step-by-step explanation:

Given that:

Old price of shoes = $65

New price of shoes = $81

Difference = 81 - 65

Difference = 16

Percent increase = [tex]\frac{Difference}{Old\ price}*100[/tex]

Percent increase = [tex]\frac{16}{65}*100[/tex]

Percent increase = 0.246 * 100

Percent increase = 24.6%

Rounding off to nearest whole number

Increase = 25%

Hence,

Percent increase = 25%

Answer:

Sale=238 Discount=42

Step-by-step explanation:

15% of 280 is 42...So 280 - 42 =238

Answer:

The shop with the best value is Tisco with .46 per can.

Step-by-step explanation:

So you need to divide 1.84 by 4 which you get .46.  Next you do 2.40 divided by 5 and you get .48.  Finally you can tell that .48 is greater than .46.

Answer:

10%

Step-by-step explanation:

1800/3 = 600

600/6000 = 10%

Answer: 3.7

Step-by-step explanation: In this case you're just multiplying by (10) usually this is done to make a decimal to a whole number

There are ten centimeters in one decimeter. How many decimeters are in thirty seven centimeters?

Divide 37/10=3.7

Another way is 3. 7*10=37

Recall two important facts:

- An isosceles triangle always has two identical angles

- The interior angles always add up to 180 degrees

Armed with this info, we can set up two different equations to solve for x, depending on which angle we treat as being one of the pair of identical angles.

If we assume that the identical angles are x, then:

180 = 2x + x + 10

170 = 3x

56[tex]\frac{2}{3}[/tex] = x

Alternately, we can assume that the identical angles are x+10.  In this case:

180 = 2(x + 10) + x

180 = 2x + 20 + x

160 = 3x

53[tex]\frac{1}{3}[/tex] = x
