Find two consecutive integers whose sum is -29

LuckyWell [14K]

Example:

The sum of two consecutive integers is -15. What is the product of the two integers?

x = 1st consecutive integer

x + 1 = 2nd consecutive integer {consecutive integers increase by 1}

x + x + 1 = -15 {the sum of two consecutive integers is -15}

2x + 1 = -15 {combined like terms}

2x = -16 {subtracted 1 from each side}

x = -8 {divided each side by 2}

x + 1 = -7 {substituted -8, in for x, into x + 1}

-8 and -7 are the two consecutive integers

Their product is 56.

A survey indicated that 2 out of 4 doctors used brand X aspirin. If 1000 doctors used brand X, how many doctors were surveyed? P

Ratling [72]

We can set this up as a proportion.

Since 2 is proportional to 1000, then 4 is proportional to "doctors surveyed".

$\frac{2}{4} = \frac{1000}{d}$ where d is the doctors surveyed.

Cross multiply.

2d = 4000
d=2000

2000 doctors were surveyed.

Diana had a large stack of playing cards. She knew that 17 of them were kings. She took a sample of 30 cards and found 4 kings.

Mandarinka [93]

Answer:

Diana approximately had 128 cards

Step-by-step explanation:

Let n be the number of cards Diana had. She knows that

there are 17 kings among n cards
4 kings among 30 cards

Write a proportion:

$\dfrac{17}{n}=\dfrac{4}{30}$

Cross multiply:

$4n=17\cdot 30\\ \\4n=510\\ \\n=\dfrac{510}{4}=127.5\approx 128$

Given the function g(x) = -7x + 12, find g(4).

Svet_ta [14]

Answer:

g(4) = - 16

Step-by-step explanation:

Substitute x = 4 into g(x) , that is

g(4) = - 7(4) + 12 = - 28 + 12 = - 16
