Okay

x+2y=3 - equation 1
2x+3y=5 -equation 2
Multiple equation 1 by 2
Giving you
2x+4y=6 - equation 3
Subtract equation 3 - equation 2
Giving you
Y=1
Put Y =1 into equation 1
Giving you
x+2(1)=3
x=3-2
x=1

OlgaM077 [116]

Answer:

4 apples are $2.40

That means that 2 apples will be $1.20

And that one apple will be $0.60

$0.60*9= $5.40

She buys 5 more apples each week so she will buy 14 apples this week

$0.60*14= $8.40

Final answer : She will buy 14 apples next week for $8.40

Hope it helped! : )

Determine which statement is a true proportion.
Ratling [72]
The answer is option B.  11/12 = (13 3/4) /15

it could be considered a true proportion if both are equal in values.

In order to find this, you need to cross multiply the numerator and the denominator in all of those options and find which give the exact result.

11 x 15  = 13 3/4  x 12

gulaghasi [49]

Answer:

1. Number of warts on a toad ⇒ <em>discrete  variable</em>

2. Survival time after poisoning ⇒ <em>continuous  variable</em>

3. Temperature of porridge ⇒ <em>continuous  variable</em>

4. Number of bread crumbs in 10 meters of trail ⇒ <em>discrete  variable</em>

5. Length of wolves’ canines ⇒ <em>continuous variable</em>

A discrete variable is the one which takes over range of real number, for a value in range that variables are permitted to take, there is minimum distance to nearest permissible value. In contrast, continuous variables are the one which can take infinitely many values.

The height of a cone is two times its base diameter. What is the volume of the cone in terms of its base radius r?​
Fudgin [204]

Answer:

B

Step-by-step explanation:

Formula for finding the volume of a cone:  V=\pi r^{2} \frac{h}{3}

From the question, we can tell that the height, h, is equal to 2d or 4r.

h = 4r.

Substitute h into the volume formula:

V=\pi r^{2} \frac{4r}{3}

Rearrange to get the final equation of:

V=\frac{4}{3} \pi r^{3}
