Solve for x. please helppp! it’s the end of the grading period

colise has 2 vases of flowers that each hold 10 red and 5 yellow roses. Michelle has the same total number of roses but in 3 vas

Maslowich

So each of Colise vases have 15 roses in them so she has a total of 30 roses 20 red and 10 yellow. Michelle also has 30 roses but he has three vases, each with 6 red roses, 6 x 3 is 18 and 30 - 18 is 12, 12/3 is 4 so Michelle would have 4 yellow roses in each of her vases.

Answer:

hope this answer will help u.

have a great time.

Step-by-step explanation:

1. 48

= 16 × 3

= 48

2. 25

= 27 -7 + 5

= 32 - 7 

= 25

3. 9

= 17 - 8

= 9

4. 36

= 144 ÷ 36 × 8 + 4

= 4 × 8 + 4

= 32 + 4 

= 36

5. 2

= 32 ÷ 16

= 2

6. 10

= 16 - 15 + 9

= 25 - 15

= 10

7. 16

= 9 + 25 - 2 × 9

= 9 + 25 - 18

= 34 - 18

= 16

8. 47

= 121 - 42 - 64 ÷ 2

= 121 - 42 - 32

= 121 - 74

= 47

Element X decays radioactively with a half life of 9 minutes. If there are 610grams of

Nookie1986 [14]

A half-life of 9 minutes corresponds to a decay factor k such that

$\dfrac12=e^{9k}\implies k=-\dfrac19\ln\left(\dfrac12\right)$

Then the time it takes for the substance to decay from 610 g to 124 g is time t such that

$124\,\mathrm g=(610\,\mathrm g)e^{kt}$

Solve for t :

$\dfrac{62}{305}=e^{kt}$

$\ln\left(\dfrac{62}{305}\right)=kt$

$t=\dfrac1k\ln\left(\dfrac{62}{305}\right)\approx20.686$

so it takes about 20.7 min for the 610 g sample to decay down to 124 g.

What is the equation of the line shown in this graph? Enter your answer in the box

IgorLugansk [536]

This is a horizontal line at y = -3. If you want to find it mathematically, you could find the slope (y2-y1)/(x2-x1) and you would get 0 over 5, so you know the slope is zero. Pick either point and substitute the numbers into point-slope formula. I went with (3, -3) and got (y - -3) = 0(x-3). The right side is just 0, and if you subtract three from both sides to isolate y, you get the equation y = -3.

Geometry question!!

Mademuasel [1]

Answer:

GQ=25 units

Step-by-step explanation:

we know that

Point Q is the midpoint of GH

so

GH=GQ+QH and GQ=QH

GH=2GQ -------> equation A

we have

GH=5x-5

GQ=2x+3

substitute in the equation A and solve for x

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

5x-5=4x+6

5x-4x=6+5

x=11

Find the length of GQ

GQ=2x+3

substitute the value of x

GQ=2(11)+3

GQ=25 units
