the correct answer is 11cm 6cm and 17cm

If 3/10 of the flowers are green and 3/4 of the rest are yellow. And the rest are purple. How many flowers do you have if you ha

mina [271]

Answer:

The total number of flowers is 680

Step-by-step explanation:

Let

x -----> the number of flowers green

y ----> the number of flowers yellow

z ----> the number of flowers purple

we know that

$x=\frac{3}{10}(x+y+z)$ ----> equation A

The rest is equal to

$\frac{7}{10}(x+y+z)$

$y=(\frac{3}{4})\frac{7}{10}(x+y+z)$

$y=\frac{21}{40}(x+y+z)$ -----> equation B

$z=(\frac{1}{4})\frac{7}{10}(x+y+z)$

$z=\frac{7}{40}(x+y+z)$ -----> equation C

Remember that

$z=119$

substitute in equation C and solve for (x+y+z)

(x+y+z) ----> is the total of flowers

$119=\frac{7}{40}(x+y+z)$

$(x+y+z)=119(40)/7$

$(x+y+z)=680$

Find the value of x

substitute in the equation A

$x=\frac{3}{10}(680)=204$

Find the value of y

substitute in the equation B

$y=\frac{21}{40}(680)=357$

therefore

The number of flowers green is 204

The number of flowers yellow is 357

The he number of flowers purple is 119

The total number of flowers is 680
