Answer:

it's a linear

since when you expand the equation (x+1)(8x-8) the x is equal to zero which is left for y to be the subject

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

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

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

$(x+y+z)=680$

<em>Find the value of x</em>

substitute in the equation A

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

<em>Find the value of y</em>

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

Straw are sold in packs and boxes there are 15 straws in each pack there are 48 straws in each box Tricia buys p packs of straws

kramer

So the expression for total number of straws is: 15p+48b

Step-by-step explanation:

We know that:

Straws in a pack = 15

Straws in a box = 48

Here

p denotes the number of packs and b is the number of boxes.

The product of number of packs and number of straws in a pack will give us the total straws in packs

15*p = 15p

Similarly, the product of number of boxes and number of straws in a box will give us the total straws in box

48*b = 48b

The sum of both will give us the total number of straws

So the expression for total number of straws is: 15p+48b

Classify the triangle with angles with measures 33, 90, and 57 as acute, right, or obtuse.

Hitman42 [59]

This triangle is classified as a right triangle because it contains one right angle (90 degrees).

An obtuse triangle is given that classification when one of the angles is greater than 90 degrees.

An acute triangle is any triangle that has all 3 angles less than 90 degrees.

If OB= 17 and AB = 30, then OR =

Novay_Z [31]

The correct answer is 8
Because
In triangle ORB
OR=(OB^2-RB^2)^1/2
OR=(17^2-15^2)^1/2
OR=(289-225)^1/2
OR=(64)^1/2
OR=8
RB=AB/2 so I kept its value 15 and ^1/2 refers to square root
