Answer:

Both groups need more boats

1.) 5x=36

36/5

=7.2 boats

2.) 7.2 but you can't split a boats nor can you decrease the amount of people so 8 boats.

3.)4x=24

24/4

=6 boats

I hope this helps u :)

Answer:

18

Step-by-step explanation:

Solve the separate part of the equation first

6(4) 6(-2) would equal 24-12

Add it back in to get: 10 - 4 + 24 - 12

-4-12 and 10+24 are the like terms so

10+24 = 34 and -4-12 = -16

Equation in the end: 34-16

Simplify that to: 34-16 = 18

Answer: 18

Step-by-step explanation: do ten minus four plus six and get twelve then dont subtract four from two add  and you get 6 add that two gether and get eighteen

Answer:

-6

Step-by-step explanation:

First, find the discount by finding 10% of $14.58. To do this, convert 0% into a decimal and multiply by $14.58.

14.58 x 0.1 = 1.458.

Since this a sale price, how much he is getting off, subtract from the total.

14.58 - 1.458 = 13.122.

We still have to find the sales tax. Solving is similar to finding the discount.

13.122 x 0.0825 = 1.082565.

Now, since it is a tax, add to the total.

13.122 + 1.082565 = 14.204565

Round to the nearest hundredth, and you have $14.20.

The sale price with after tax is $14.20.

Answer:

{y,x} = {7,-1}

Step-by-step explanation:

(-7x) + 3x = 4

- 4x = 4

 4x = - 4

x = - 1

   y = -7x

   x = -1

   y = -7(-1) = 7

Answer:

The required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]

Step-by-step explanation:

In this question we need to find the equation of the graph in factored form.

The factored form will be: [tex]f(x)=a(x-r_1)(x-r_2)..[/tex]

where a is y-intercept and r₁, r₂ are x-intercepts

X-intercepts

When y=0, the values of x axis are known as x-intercepts

Y-intercepts

When x=0, the values of y-axis are known as y-intercepts.

Looking at the graph finding x-intercepts

When y=0 x=-2 and 1

So, we have

r₁ = -2

r₂ = 1

Looking at the graph finding y-intercepts

When x=0, y=-4

So, a = -4

Putting values in the formula we will get:

[tex]f(x)=a(x-r_1)(x-r_2)\\f(x)=-4(x-(-2))(x-1)\\f(x)=-4(x+2)(x-1)[/tex]

So, the required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]

Answer:

[tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Step-by-step explanation:

Given

P = Test is positive

D = Disease is present

Required

Write an expression when disease is present but test says that the disease is not present

The above statement can be split to two

Disease is Present          &        Test is not positive

The first statement:

Disease is Present  means D

The second statement

Test is not positive means not P

Mathematically;

not P means P' or [tex]P^c[/tex]

So, the required expression is: [tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Answer:

3

Answer:

A = 58.9 degrees

Step-by-step explanation:

straight line angles add up to 180 degrees

121.1 + A = 180

A = 180 - 121.1

A = 58.9 degrees

Answer:

its A on the quiz (alternate interior)

Step-by-step explanation:

The required angle relationship describes ∠VQR and ∠QRW is both angles are alternate interior angles. Option A is correct.

Given that,
Segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively. What angle relationship describes ∠VQR and ∠QRW is to be determined.

Parallel lines are defined as the pair of line that has the distance between the point corresponding to the line are equal and this line met at infinity.

The angle can be defined as the one line inclined over other line.

Since it is to describe that what is the relationship between  ∠VQR and ∠QRW.
Here, both angles are interior and alternate in the figure so both angles have a relationship to the alternate interior angle by property of parallel lines.

Thus, the required angle relationship describes ∠VQR and ∠QRW is both angles are alternate interior angles. Option A is correct.

Step-by-step explanation:

by having two equations that have the same point, you can set the two equations equal to each other

y = 12x + 3, y = x + 1

12x + 3 = x + 1

11x = -2

x = -2/11

when you find the the x value, plug it back into either one of the equations

y = x + 1

y = (-2/11) + 1

y = 11/11 - 2/11

y = 9/11

the point (solution):

(-2/11, 9/11)

Answer:

(-2|11, 9|11)

Answer:

72

Step-by-step explanation:

If BFD is a right angle and it gives you CFD that means that you do 90 - 72 to find CFB cause it 90 all togther

CFB = 18 deg

now it also tells us CFA is a 90 deg angle so we do the same thing

90 - 18 = 72
