Answer: 34°

Step-by-step explanation:

1. 4x+3x-8=90, add 8 to both sides, so -8 cancels on the left side and 90 becomes 98. Then combine 4x and 3x, you get 7x=98, finally divide both sides by 7, the 7 on the left side cancels and 98 becomes 14. So X=14.

2. Now input 14 into 3x-8. So 3(14)-8=34°, check your work by input 14 in 4x and then adding them both together, they should equal 90. So 4(14)=56 and 34+56=90 so 34° is correct.

Answer:

The answer is (4,4)

Step-by-step explanation:

I had this same problem and got it right so can you give me 5 stars:)

The solution of the system of equations –3x + y = –8 and x + 2y = 12 will be (4,4).

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraints.

Given,

–3x + y = –8 and x + 2y = 12

Multiplying by 2 to equation first

-6x + 2y = -16 and x + 2y = 12

Substracted equation second to first

7x = 28

x = 4

By substituting

y = 4

Hence "The solution of the system of equations –3x + y = –8 and x + 2y = 12 will be (4,4)".

Step-by-step explanation:

Answer:

650 tickets for the main floor and 475 tickets for the balcony were sold.

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=1125 (1)

8x+6y=8050 (2), where:

x is the number of tickets for the main floor

y is the number of tickets for the balcony

First, you can solve for x in (1):

x=1125-y (3)

Second, you can replace (3) in (2):

8(1125-y)+6y=8050

9000-8y+6y=8050

9000-2y=8050

9000-8050=2y

950=2y

y=950/2

y=475

Third, you can replace the value of y in (3) to find x:

x=1125-y

x=1125-475

x=650

According to this, the answer is that 650 tickets for the main floor and 475 tickets for the balcony were sold.

Answer:

Options (1), (2), (3)

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here m = slope of the line

b = y-intercept

Given line on the graph is passing through two points (-3, 0) and (0, 1).

Slope of this line will be,

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

   = [tex]\frac{1-0}{0+3}[/tex]

   = [tex]\frac{1}{3}[/tex]

y-intercept of the line 'b' = 1

Equation of the line will be,

y = [tex]\frac{1}{3}x+1[/tex]

If the points given in the options satisfy the equation, they will be the solution of the line.

Option (1),

For (3, 2),

2 = [tex]\frac{3}{3}+1[/tex]

2 = 2

True.

(3, 2) is the solution.

Option (2)

For (21, 8),

8 = [tex]\frac{21}{3}+1[/tex]

8 = 8

True.

(21, 8) is the solution.

Option(3)

For (-15, -4),

-4 = [tex]\frac{-15}{3}+1[/tex]

-4 = -4

True.

(-15, -4) is the solution.

Option (4)

For (12, 9)

9 = [tex]\frac{12}{3}+1[/tex]

9 = 5

False

(12, 9) is not the solution.

Option (5)

For (-6, 1)

1 = [tex]\frac{-6}{3}+1[/tex]

1 = -1

False

(-6, 1) is not the solution.

Therefore, Options (1), (2), (3) are the solutions.

Answer:

The value of k = 4.6 m

Step-by-step explanation:

As you see in the question diagram, quadrilateral WXYZ  is the same shape as quadrilateral ABCD, but it's two times larger.

The reason is that one of the lengths BC of the quadrilateral ABCD is 4.2 m, and its corresponding length XY of the quadrilateral WXYZ is twice times larger.

i.e. 4.2 × 2 = 8.4 m

As the quadrilaterals are similar. It means if the length CD of the quadrilateral ABCD is 2.3 m, its corresponding length YZ of the quadrilateral WXYZ must be twice times larger.

i.e. 2.3 × 2 = 4.6 m

Therefore, the value of k = 4.6 m

Answer:

The answer is

Speed of the boat in still water= 12mph

Speed of current= 9mph

Step-by-step explanation:

let x= speed of the boat in still water

let y= speed of current

DATA WE HAVE

with current  

rate- x+y        

time- 6 hours

distance- 126 miles

rate= 126/6= 21

against current

rate- x-y

time- 42hr

distance- 126 miles

126/42= 3

Now, we add these two equations vertically.

x-y=3

+

x+y=21            

2x = 24

Now we divide each side by 2

2x/2   24/2

x= 12

The speed of the boat in still water is 12mph

NOW WE HAVE HALF OF THE ANSWER

if x+y= 21

then

12+y=21

subtract 12 from both sides

y=9

The speed of the current is 9mph

Checking)

12+9=?21

21=21

12-9=?3

3=3

The speed of the boat in still water is 6 mph, and the speed of the current is 4.5 mph.

Given that a boat traveled 126 miles downstream and back, and the trip downstream took 6 hours, while the trip back took 42 hours, to determine what is the speed of the boat in still water and what is the speed of the current, the following calculations must be performed:

Therefore, the speed of the boat in still water is 6 mph, and the speed of the current is 4.5 mph.

Answer:

you need to find out how many miles per hour irst then see how many itll be in 24 hours

Step-by-step explanation:

Answer:

D = 6.2t, where t is in hours

Now, solve for 24 hours for t.

D = 6.2(24) = 148.8 miles in 24 hours.

Step-by-step explanation:

First, find out how far the butterfly can fly in 1 hour.

93 miles / 15 hours = 6.2 miles per hour

Let D = the distance in miles the butterfly can fly in t hours.

Your equation will be

D = 6.2t, where t is in hours.

Answer: x=11/36

Step-by-step explanation:

Step One-Subtract 1/6 from both sides.

2x+1/6-1/6=7/9-1/6

2x=11/18

Step Two-Divide both sides by 2.

2x/2=11/18/2

x=11/36.
