3(6-4x)-27x=10x-31

18-12x-27x=10x-31

18-39x=10x-31

-49x=-49

Therefore, x=1.


s/6-s/2+1=45/2.

s-3s+6=135

-2s=129

Therefore, s=-\frac{129}{2}.


2(b+5)=3(4-b)

2b+10=12-3b

5b=2

b=\frac{2}{5}

Answer: see work below

Step-by-step explanation:

1) 3(2f + 4)

distribute the 3

= 6f + 12

2) 3(4t + 2)

distribute the 3

= 12t + 6

3) 7(6k -2v)

distribute the 7

= 42k - 14v

4) 5(2q - 9)

distribute the 5

= 10q - 45

(im not sure what the red mark is. if it's a negative than my answer would be opposite: -10q + 45)

5) 3(2e + 5t)

distribute the 3

= 6e + 15t

(im not sure what the red mark is. if it's a negative my answer would be opposite: -6e -15t)

6) 4(3r - 5)

distribute the 4

= 12r - 20

The accompanying table shows the value of a car over time that was purchased for
Dafna1 [17]

The value of the car after 11 years is $3137.18

<h3>exponential function</h3>

An exponential function is in the form:

y = abˣ

where a is the initial value of y, b is the factor, y, x are variables.

Let y represent the value of the car in dollars after x years. From the table:

When x  = 0, y = 12700, hence:

  • 12700 = ab°
  • a = 12700

When x = 2, y = 9849, hence:

  • 9849 = 12700b²
  • b = 0.8806

The exponential function is:

y = 12700(0.8806)ˣ

For 11 years:

y = 12700(0.8806)¹¹ = 3137.18

The value of the car after 11 years is $3137.18

In a study of
o-na [289]
We know that:
Mean = 82 mm and SD = 10 mm ( standard deviation )
82 - 3 * SD = 82 - 3 * 10 = 82 - 30 = 52 mm
82 + 3 * SD = 82 + 3 * 10 = 82 + 30 = 112 mm
Population between 52 and 112 mm is within +/- 3 standard deviations from the mean.
By the 66- 95 - 99.7 % rule it is: 99.7% of the test group.
0.977 * 500 = 498.5
Answer:
99.7 % of the test group have a diastolic pressure between 52 and 112 mm, or 498 men.
