Answer:

In order to solve these, you must combine your variable terms and move them till they are isolated from your constants. Divide until the variable is alone on one side.

Answer:

1. 7

Step-by-step explanation:

1. 8y= 37+ 35

Subtract 3y from both sides of the equation:

8y - 3y = 3y + 35 - 3y

simplify:

combine like terms

than combine like terms again

5y= 35

Divide both sides of the equations by the same term:

5y = 35

[tex]\frac{5y}{5} = \frac{35}{5}[/tex]

simplify:

cancel terms that are in both the numberator and denominator

divide numbers

Answer:

[tex]x=\dfrac{d}{(5+10f)}[/tex]

Step-by-step explanation:

The given equation is :

d = 5x + 10xf

We need to solve the above equation for x.

Taking x common from RHS,

d=x(5+10f)

Dividing both sides by (5+10f),

[tex]x=\dfrac{d}{(5+10f)}[/tex]

Hence, this is the required value of x.

Answer:

X=1

Step-by-step explanation:

0=4x-4

-4x=-4

-4x/-4=-4/-4

x=1

[tex]m=\frac{\Delta y}{\Delta x}=\frac{-2-6}{16-(-30)}=\frac{-8}{46}=\boxed{-\frac{4}{23}}[/tex].

Answer:

A third place vote is worth 1 point

Step-by-step explanation:

Let the number of points for a first place vote be x, number of points for a second place vote be y and the number of points for a third place vote be z.

So, by multiplying the number of points by the number of what the point is worth and adding all together, we shall have the total points;

Hence, we have the following equation systems;

23x + 5y + z = 131

5x + 17y + 4z = 80

x + 5y + 15z = 35

These are the three equations we need to solve simultaneously to get the value of z

From equation 3, x = 35 -5y -15z

Insert this into the first two equations;

23 ( 35 -5y -15z) + 5y + z = 131

5(35-5y-15z) + 17y + 4z = 80

805 - 115y -345z + 5y + z = 131

805-131 = 115y + 345z -5y - z

674 = 110y + 344z ••••••••••(*)

The second equation now becomes the following;

5(35-5y-15z) + 17y + 4z = 80

175 -25y -75z + 17y + 4z = 80

175-80 = 25y + 75z -17y -4z

95 = 8y + 71z

8y + 71z = 95 •••••••••••(**)

So we have to solve x and xx simultaneously;

110y + 344z = 674

8y + 71z = 95

110/8 = 13.75 , so multiply equation xx by 13.75 and equation x by 1

110y + 344z = 674

110y + 976.25z = 1306.25

Subtract equation xx from x

(976.25z - 344z) = (1306.25 -674)

632.25z = 632.25

z = 632.25/632.25

z = 1

Answer:

6 seconds

Step-by-step explanation:

Initial distance of Mario from motion detector = 2 ft

Speed of Mario = 1.5 ft/sec

Total distance of Mario from motion detector = 11 ft

Total distance moved by Mario while walking at the rate of 1.5 ft/sec = 11 - 2 = 9 ft

Given that:

Distance = 9 ft

Speed = 1.5 ft/sec

Formula:

[tex]Distance = Speed \times Time[/tex]

[tex]\Rightarrow 9 =1.5 \times Time\\\Rightarrow Time = \dfrac{9}{1.5}\\\Rightarrow Time = \bold{6\ sec}[/tex]

So, at 6 seconds, Mario will be 11 ft from the motion detector.

x=8. or x=-4

Now we now the 2 x.

8+ -4/2 = 2 seconds

Answer:

-44

Step-by-step explanation:

So you want to plug 2 in for t, so the equation should now look like:

[tex]2^{2}[/tex] - 44 - 4

No all you have to do is solve

[tex]2^{2}[/tex] = 4

4 - 44 = -40

-40 - 4 = -44

Answer:

-44

Step-by-step explanation:

t=2, t² - 44 - 4

1. substitute in the value to the variable: 2² - 44 - 4

2. using PEMDAS, solve the equation: 2² - 44 - 4 = 4-44-4 = -40-4= -44

(evaluate the exponent, then subtract)

Hi there!

The domain is:

20<=x<=40

Step-by-step explanation:

This states that:

x>=20

x<=40

Which fits the problem!

Hope this helps

For a given function f(x) we define the domain as the set of possible values of x that we can use in the function.

Here we will find that the domain is D: [20h, 40h]

We know that Ally wins $18 per hour, and she has two restrictions:

She cant' work more than 40 hours.

She needs to work at least 20 hours.

Then her weekly salary can be written as:

s(x) = $18*x

Where x is the number of hours that she works each week.

With the above restrictions we have:

20h ≤ x ≤ 40h

Then the domain is:

D: [20h, 40h]

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

(a)

To find the first 4 terms substitute n = 1, 2, 3, 4 into the n th term formula.

a₁ = 1 + 5 = 6

a₂ = 2 + 5 = 7

a₃ = 3 + 5 = 8

a₄ = 4 + 5 = 9

For the 10 th term substitute n = 10, that is

a₁₀ = 10 + 5 = 15

The first 4 terms are 6, 7, 8, 9 and the 10 th term is 15

(b)

Substitute n = 1, 2, 3, 4 and 10 into the n th term formula

a₁ = 2(1) - 1 = 2 - 1 = 1

a₂ = 2(2) - 1 = 4 - 1 = 3

a₃ = 2(3) - 1 = 6 - 1 = 5

a₄ = 2(4) - 1 = 8 - 1 = 7

a₁₀ = 2(10) - 1 = 20 - 1 = 19

The first 4 terms are 1, 3, 5, 7 and the 10 th term is 19

Answer:

Probability that the whole shipment will be accepted = 0.9660

96.60% of the shipment will be accepted

Almost all the shipments will be accepted

Step-by-step explanation:

We are given;

n = 41

p = 3% = 0.03

x = 3

This is a binomial probability question and we will use the formula;

P(X = x) = [n!/(x!(n - x)!)] × p^(x) × (1 - p)^(n - x)

The probability that the whole shipment will be accepted is given by the form;

P(X ≤ 3) = P(0) + P(1) + P(2) + P(3)

P(3) = [41!/(3!(41 - 3)!)] × 0.03³ × (1 - 0.03)^(41 - 3)

P(3) = 0.09046

P(2) = [41!/(2!(41 - 2)!)] × 0.03² × (1 - 0.03)^(41 - 2)

P(2) = 0.22496

P(1) = [41!/(1!(41 - 1)!)] × 0.03¹ × (1 - 0.03)^(41 - 1)

P(1) = 0.36373

P(0) = [41!/(1!(41 - 0)!)] × 0.03^(0) × (1 - 0.03)^(41 - 0)

P(0) = 0.28684

Thus;

P(X ≤ 3) = 0.28684 + 0.36373 + 0.22496 + 0.09046

P(X ≤ 3) = 0.96599 ≈ 0.9660

It means that 96.60% will be accepted
