What is the answer negative one times the sum of one and seven times a number, decreased by 6 times the difference of negative s

Setler79 [48]

Answer:

The number is -79.

Step-by-step explanation:

Let's set up equation for the given information.

Let the number as 'x'

Negative 1 times the sum of one and seven times a number x could be written as -1(1+7 x).

Now, 6 times the difference of negative seven and a number could be written as

6(-7-x)

Now,

-1(1+7 x) decreased by 6(-7-x) equals 36

So, we can set up equation as

-1(1+7 x)-6(-7-x)=36

Solve the equation for x

-1-7 x-42+6 x=36

Combine like terms

-x-43 =36

Add both sides 43

-x=79

Divide both sides by -1.

x=79

Roger can run one mile in 18 minutes. jeff can run one mile in 15 minutes. if jeff gives roger a 1 minute head start, how long w

gladu [14]

Alright, lets get started.

Roger can run one mile in 18 minutes.

Jeff can run one mile in 15 minutes.

Suppose in x minutes, they both will catch up.

Roger runs in 18 minutes = 1 mile

So, Roger will run in 1 minute = $\frac{1}{18}$ miles

So, Roger will run in x minutes = $\frac{x}{18}$ miles

Jeff runs in 15 minues = 1 mile

So, Jeff will run in 1 minute = $\frac{1}{15}$ mile

As Jeff gives roger a 1 minute head start, means Jeff will have x-1 minute time to run

So, Jeff will run in (x-1) minute = $\frac{x-1}{15}$

As both are cathing up means they both runs same distance, means

$\frac{x}{18} =\frac{x-1}{15}$

Cross Multiplying

$15 x = 18x - 18$

$3 x = 18$

x = 6 minutes

So for calculating distance = $speed * time$

Distance = $\frac{1}{18} *6 = \frac{1}{3}$ miles

It means it will take 1/3 or 0.33 miles before jeff catches up to roger. : Answer

Hope it will help :)

What are the values Of p and q ?

ValentinkaMS [17]

The values of p and q in the function f(x) = 2x³ + 17x² - 3px - 5q is p = 8, q = 27

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

x - 3 (i.e. x = 3) and x + 9 (i.e. x = -9) are factors of f(x) = 2x³ + 17x² - 3px - 5q

Hence:

f(3) = 0

2(3)³ + 17(3)² - 3p(3) - 5q = 0 (1)

Also:

2(-9)³ + 17(-9)² - 3p(-9) - 5q = 0 (2)

Hence, p = 8, q = 27

The values of p and q in the function f(x) = 2x³ + 17x² - 3px - 5q is p = 8, q = 27
