Answer: x = 7

Explanation:

Subtract 8 from both sides to isolate x.

x + 8 = 15

x + 8 -8 = 15 - 8

x = 15 - 8

x = 7

Answer:

X=7

Step-by-step explanation:

Answer:

c = 15t

Step-by-step explanation:

Given that:

Unit cost of Ticket = $15

Total cost = unit cost * number of tickets purchased

Total cost = c

Number of tickets purchased = t

C = $15 * t

c = 15t

the lebgth to form the right angle is e9

Answer:

y=-2x+1

Step-by-step explanation:

First, you calculate the slope, which is rise over run: -9+5 / 5-3 = -2.  Then, find b by substituting the coordinates (of either one point) into the slope-intercept formula, y = mx + b.  

Answer:

Step-by-step explanation:

The slope intercept form of a line is

y=mx+b, where m=slope and b= y intercept

The slope of a line is defined as

m=(y2-y1)/(x2-x1), in this case we have points (3,-5) and (5,-9)

m=(-9-(-5))/(5-3)

m=-4/2

m=-2, so our line is now

y=-2x+b, using point (3,-5) we can now solve for b

-5=-2(3)+b

-5=-6+b

1=b so the completed line is

y=-2x+1

Step-by-step explanation: When you count to five, the numbers that are listed above, (1, 2, 3, 4) are the right answers

Answer:

1 dog, 2 birds

Step-by-step explanation:

Birds have two legs. 2x2=4

Dogs have 4 legs. 4x1=4

4+4=8

the answer will be 5.6 !

you can get this by doing 8.9 - 3.3 ! remember you can apply this to all problems by turning division to multiplication, addition to subtraction, etc.

Answer:

Triangle

Step-by-step explanation:

A pyramid is a strong-solid shape that is comprised of triangles, square shapes, squares, and different polygons. Pyramids are arranged depending on the state of their base. For instance, the outline given is a square-based pyramid in light of the state of its base(which is a square). Different sorts incorporate the three-sided based pyramid, three-sided based pyramid, and other polygon-based pyramids.  

In the event that this square pyramid is cut with a plane that is corresponding to the base of the pyramid, the state of its cross-area will be a triangle since the shapes that are corresponding to the base are altogether triangles. So slicing the plane corresponding to the base is like removing one side of the triangle making up the pyramid.

Answer:

40 degrees

Step-by-step explanation:

Answer:

I wanna say the answer is 40.

Step-by-step explanation:

Because the line going through will most likely make the same degree on the other side.

Answer:56.55

Step-by-step explanation:

[tex] \bf \underline{ \underline {Given}}[/tex]

Radius = 9 cm

[tex] \bf \underline{ \underline{To \: find \: out }}[/tex]

Find the circumference of given circle.

[tex] \bf \underline{ \underline{Formula \: used}}[/tex]

[tex] \sf \: Circumference \: of \: circle = 2 \pi \: r [/tex]

[tex] = 2 \times \dfrac{22}{7} \times 9[/tex]

[tex] = \dfrac{44}{7} \times 9[/tex]

[tex] = \dfrac{396}{7} [/tex]

[tex] = 56.57 \: cm[/tex]

Step-by-step explanation:

anywhere from 9 and 11 to 14 and 16.... I feel like there is something missing in the question

Given:

A deep sea diver started at sea level (0 feet).

Rate of diving = 5.6 feet per minute.

Time = [tex]\dfrac{1}{2}[/tex] hour

To find:

The rational number that represents his position relative to sea level.

Solution:

We know that,

1 hour = 60 minutes

[tex]\dfrac{1}{2}[/tex] hour = 30 minutes

A deep sea diver, dove at a rate of 5.6 feet per minute.

Distance covered in 1 minute = 5.6 feet

Distance covered in 30 minute = 30 × 5.6 feet

                                                    = 168 feet

The diver dove 168 feet in [tex]\dfrac{1}{2}[/tex] hour. Since it is below the sea level, therefore it should be negative.

So, the rational number that represents his position relative to sea level is [tex]-168[/tex] feet.

Therefore, the correct option is D.

Answer:

Andrew's total income for this month is $4762.5.

Step-by-step explanation:

With the information provided, you can find the total income by calculating 5% of the sales this month and adding up this amount to his monthly salary:

sales=10,250

monthly salary=4,250

10,250*5%=512.5

4,250+512.5=4,762.5

According to this, the answer is that Andrew's total income for this month is $4,762.5.

y< −43 /83

but if you want a decimal  

-0.518072

Step-by-step explanation:

Answer: A

Step-by-step explanation: this is the correct answer

Answer:

x = 8

Step-by-step explanation:

f(x) = [tex]\sqrt{3x}[/tex]

g(x) = [tex]\frac{1}{x+3}[/tex]

(f o g)(x) = f[g(x)]

             = [tex]\sqrt{\frac{3}{x+3} }[/tex]

This function is defined for (x + 3) > 0

(x + 3) - 3 > 0 - 3

x > -3

From the given options x = 8 is the only solution which is greater than -3.

Therefore, x - 8 is in the domain of the given function.
