Answer:

Olivia is 9 years old.

Step-by-step explanation:

1/3 of o (Olivia's age) increased by 12, is twice of o minus 3. The equation for this would be 1/3o + 12 = 2o - 3. (The left side could be o/3 as well.)

1/3o + 12 = 2o - 3

Subtract 2o from both sides

-5/3o + 12 = -3

Subtract 12 from both sides

-5/3o = -3 - 12

Subtract 12 from -3 to get -15

-5/3o = -15

Multiply both sides by -3/5, the reciprocal of -5/3

o = -15 (-3/5)

Express -15(-3/5) as a single fraction

o = -15 (-3)/5

Multiply -15 by -3 to get 45

o = 45/5

Divide 45 by 5 to get 9.

o = 9

To make sure this works, substitute 9 for o.

1/3(9) + 12 = 2(9) - 3

3 + 12 = 18 - 3

15 = 15

Both sides match each other, so o equals 9.

Olivia is 9 years old

Twice her age decreased by 3 is expressed as 2x - 3

Equate both expressions and find x

1/3x + 12 = 2x - 3

1/3x - 2x = -3-12

(x-6x)/3 = -15

-5x = -45

x = 9

Hence Olivia is 9 years old

Answer:

C. y ≤ 0

D. 18 bags of chips and 6 jars of salsa

Step-by-step explanation:

It is C because, it is over the x axis and it covers all the negative y's.

__________________________________________________________

2.5x + 4y ≤ 60

2.5(10) + 4(2) ≤ 60

25 + 8 ≤ 60

33 ≤ 60

It fits so A doesn't work

2.5x + 4y ≤ 60

2.5(20) + 4(2) ≤ 60

50 + 8 ≤ 60

58 ≤ 60

It fits so B doesn't work

2.5x + 4y ≤ 60

2.5(14) + 4(5) ≤ 60

35 + 20 ≤ 60

55 ≤ 60

It fits so C doesn't work

2.5x + 4y ≤ 60

2.5(18) + 4(6) ≤ 60

45 + 24 ≤ 69

It doesn't fit therefore, your answer would be D. 18 bags of chips and 6 jars of salsa.

Answer:  The slope is -3/2

Step-by-step explanation:

To find the slope, find the difference in the y coordinates and divide it by the difference in the x coordinates.

y coordinates;   9 - 15 = -6

x coordinates : 8 - 4 = 4  

Slope:     -6/4  =   -3/2

Answer:

Ur answer is in the screenshot :)  

Step-by-step explanation:

1. Subtract 2x2x from both sides. 3y=5x-y-2x

3y=5x−y−2x

2. Simplify  5x-y-2x5x−y−2x  to  3x-y3x−y.

3y=3x-y

3. Add yy to both sides.3y+y=3x

3y+y=3x

4. Simplify  3y+y3y+y  to  4y4y. 4y=3x

4y=3x

5. Divide both sides by 33.\frac{4y}{3}=x34y=x

6. Switch sides.x=\frac{4y}{3}

x= 34y! Hope this helped!! :))

Given:

A line segment is between the points (1,-2) and (-2,10).​

To find:

The gradient of the given line segment.

Solution:

We know that gradient of the given line segment means slope of the line segment.

The line segment between the points (1,-2) and (-2,10).​ So, slope of the line segment is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{10-(-2)}{-2-1}[/tex]

[tex]m=\dfrac{10+2}{-3}[/tex]

[tex]m=\dfrac{12}{-3}[/tex]

[tex]m=-4[/tex]

Therefore, the gradient of the given line segment is -4.

Answer: the probability that I, Samuel Lisa and Andrew are chosen is 0.0003

Step-by-step explanation:

Given that;

Number of 4 employees are to be chosen from 19 of them;

so Number of ways to choose 4 employees from 19 employees = ?

we know that;

c(n,r) = [tex]\left[\begin{array}{ccc}n\\r\end{array}\right][/tex] = n! / ( r!(n-r)!)

so we substitute

c(19,4) = [tex]\left[\begin{array}{ccc}19\\4\end{array}\right][/tex] = 19! / ( 4!( 19-4 )!) = 3876

so the probability that I, Samuel Lisa and Andrew are chosen will be;

⇒ 1 / 3876 = 0.0002579 ≈ 0.0003

the probability that I, Samuel Lisa and Andrew are chosen is 0.0003
