8 0

Answer:

s=2r

Step-by-step explanation:

Solution:

Given;

2q-r=p

r=q-s

or,q=r+s

p=q+2r

To prove: s=2r

Now,

2q-r=p

or,2(r+s)-r=q+2r

or,2r+2s-r=r+s+2r

or,r+2s=3r+s

or,s=2r

PROVED

Bryan cut two peaches that were the same size for lunch. he cut one peach into fourths and the other into sixths. bryan ate 3/4

3/4 and 5/6
Now, you have to find the common denominator to compare the two fractions properly. Let’s see... 12 can be divided by both 4 and 6. So we’re going to convert both denominators to 12.

3*3= 9 and 4*3=12 so 3/4 = 9/12

5*2= 10 and 6*2=12 so 5/6 = 10/12

Bryan’s brother ate more peach.

Write the sentences as proportion. Twelve hundredths is to three as twenty-four hundredths is to eight
ValentinkaMS [17]

Answer:

see the explanation

Step-by-step explanation:

Remember that

A proportion is the ratio (quotient) between two numbers

so

Twelve hundredths to three is ----> \frac{0.12}{3}

Twenty-four hundredths to eight ----> \frac{0.24}{8}

therefore

Twelve hundredths is to three as twenty-four hundredths is to eight

\frac{0.12}{3}=\frac{0.24}{8}

Note The proportion is not true

Find all values of x that make the triangles congruent. Explain your reasoning.
RSB [31]

Answer:

x = \frac{4}{5},5

Step-by-step explanation:

If both the triangles ΔABC and ΔBCD are congruent,

Corresponding sides of both the triangles will be proportional.

\frac{AB}{BD}=\frac{AC}{CD}

\frac{5x}{3x+10}=\frac{5x-2}{4x+3}

5x(4x + 3) = (5x - 2)(3x + 10)

20x² + 15x = 15x² + 50x - 6x - 20

20x² + 15x = 15x² + 44x - 20

20x² - 15x² = 44x - 15x - 20

5x² = 29x - 20

5x² - 29x + 20 = 0

5x² - 25x - 4x + 20 = 0

5x(x - 5) - 4(x - 5) = 0

(5x - 4)(x - 5) = 0

x=\frac{4}{5},5

Find the rectangular coordinates of (7, 150°)
Y_Kistochka [10]

Answer:

The coordinates are (-7sqrt(3)/2, 7/2).

Step-by-step explanation:

The rectangular coordinates from polar coordinates is found by:

x = r*cos(theta)

y = r*sin(theta)

Substituting the given values, we get:

x = 7*cos(150 deg) = 7*(-sqrt(3)/2) = -7sqrt(3)/2

y = 7*sin(150 deg) = 7*(1/2) = 7/2

The coordinates are (-7sqrt(3)/2, 7/2).

I hope this helps! :)
