Answer:

x = 10

y = 15

Step-by-step explanation:

Angles 8x - 10 and 7x are congruent because they are alternate interior angles of parallel lines cut by a transversal.

8x - 10 = 7x

x = 10

7x = 7(10) = 70

6y + 20 and 7x are supplementary since they are a linear pair.

6y + 20 + 7x = 180

6y + 20 + 70 = 180

6y = 90

y = 15

The ratio of ages of kissi and esinam is 3:5 and esinam is 3:5 The sum of ages of all 3 is 147 years.whats the age difference be

Sergio039 [100]

Answer:

48 years.

Step-by-step explanation:

Consider the complete question is "The ratio of ages of kissi and esinam is 3:5 and that of esinam and lariba is 3:5. The sum of ages of all 3 is 147 years. whats the age difference between oldest and youngest ?"

It is given that

Kissi : Esinam = 3:5 = 9:15

Esinam : Lariba = 3:5 = 15:25

So, the combined ratio is Kissi : Esinam : Lariba = 9:15:25

Let ages of Kissi, Esinam, Lariba are 9x, 15x and 25x.

Sum of ages of all 3 is 147 years.

$9x+15x+25x=147$

$49x=147$

$x=3$

The value of x is 3. So, the age of all three are

$Kissi=9x=9(3)=27$

$Esinam=15x=15(3)=45$

$Lariba=25x=25(3)=75$

Since Lariba is oldest and Kissi is youngest, therefore, the difference between their ages is

$75-27=48$

Hence, difference between oldest and youngest is 48 years.

The graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.

ICE Princess25 [194]

Answer:

The weights within this range are:

8.9

9.5

9.8

10.4

Step-by-step explanation:

The graph represents the normal distribution with a mean of 9.5 and a standard deviation of 0.5. Therefore, the range of the values within 2 standard deviations is:

9.5 - 2(0.5) ≤ x ≤ 9.5 + 2(0.5)

8.5 ≤ x ≤ 10.5

(ASAP PICTURE ADDED) What is the simplified form of the following expression?

bonufazy [111]

Answer:

option c is correct.

Step-by-step explanation:

$7\left(\sqrt[3]{2x}\right)-3\left(\sqrt[3]{16x}\right)-3\left(\sqrt[3]{8x}\right)$

WE need to simplify this equation.

Solve the parenthesis of each term.

$=7\left\sqrt[3]{2x}\right-3\left\sqrt[3]{16x}\right-3\left\sqrt[3]{8x}\right$

Now, We will find factors of the terms inside the square root

factors of 2: 2

factors of 16 : 2x2x2x2

factors of 8: 2x2x2

Putting these values in our equation: $=7\left(\sqrt[3]{2x}\right)-3\left(\sqrt[3]{2X2X2X2 x}\right)-3\left(\sqrt[3]{2X2X2 x}\right)\\=7\left(\sqrt[3]{2x}\right)-3\left(\sqrt[3]{2X2X2} \sqrt[3] {2 x}\right)-3\left(\sqrt[3]{2X2X2} \sqrt[3]{x}\right)\\=7\left(\sqrt[3]{2x}\right)-3\left(\sqrt[3]{2^3} \sqrt[3] {2 x}\right)-3\left(\sqrt[3]{2^3} \sqrt[3]{x}\right)\\=7\left(\sqrt[3]{2x}\right)-3*2\left(\sqrt[3] {2 x}\right)-3*2\left(\sqrt[3]{x}\right)\\=7\left(\sqrt[3]{2}\sqrt[3]{x}\right)-6\left(\sqrt[3] {2}\sqrt[3]{x})-6\left(\sqrt[3]{x}\right)$

Adding like terms we get:

$=7\left(\sqrt[3]{2}\sqrt[3]{x}\right)-6\left(\sqrt[3] {2}\sqrt[3]{x})-6\left(\sqrt[3]{x}\right\\=(\sqrt[3] {2}\sqrt[3]{x})-6\left(\sqrt[3]{x}\right)\\$

$(\sqrt[3] {2}\sqrt[3]{x})-6\left(\sqrt[3]{x}\right)\\can\,\,be \,\, written\,\, as\,\,\\(\sqrt[3] {2x})-6\left(\sqrt[3]{x}\right)$

So, option c is correct

Solve 3x^2 = −12x − 15.

vitfil [10]

3x^2+12x+15=0

Then divide by 3 to get the x by itself.
x^2+4x+5=0

Factor to (x+5) (x-1) and solve for the two values of x.
