Answer:

y/2 = 4.5

Step-by-step explanation:

1/4x + 2y = 11/4

distribute by 4 to eliminate fractions

  x + 8y = 11

+ -x - 6y = 7

        2y = 18

          y = 9

half of 9 = 4 1/2

Answer:

Step-by-step explanation:

x=-3 and y=5

f(-3)=5

Answer:

at 12 hours, it's 9 inches.

at 14 hours, it's 14 inches.

at 13 hours it's 16 inches.

I'm not sure if you needed how many inches it snowed an hour, or if you just needed the hours and inches. My apologies.

Answer:

$123.75

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

I added all the things she bought and subtracted it by the total and got B. 123.75

Answer:

Step-by-step explanation:

x = -y + 10

Substitute into the second equation

-y + 10 = y + 4

-2y = -6

y = 3

Plug into first or second equation.

x = -3 + 10 = 7

x = 3 + 4 = 7

So the ordered pair is (7,3)

Answer:

y-4=3(x+2)

Step-by-step explanation:

Plug into point slope equation with slope m and point (x1,y1)

y-y1=m(x-x1)

y-4=3(x+2)

Answer:

54 degrees

Step-by-step explanation:

Every side of a regular pentagon is same.

So we have an  isosceles triangle. The  correspond angle of y, must equal to y (degree) too.

Also, every inner angle of a regular pentagon is 360/5=72. So we can calculate angle y, by the equation y+y+72=180.

y=54

Step-by-step explanation:

The dot is called a decimal point. It is also called the decimal separator. It separates whole numbers from fractional numbers.

In this example;

24.671

The numbers before the point, 24 is the whole number

The numbers after the point, 671 are the fractional portion of the number. They represent 6 tenths, 7 hundredths and 1 thousandths.

Also, the number of digits after the point tells you how many decimal place the number is in. In this example the number of decimal places is 3.

Answer:

Step-by-step explanation:

First, find yourself a map. Then, using two points, find both the distance on the map and the true distance. Next, you divide the true distance by the measured map distance, and find your scale. Last, you need to place that ratio onto your map.

Answer: A is multiplied by  2  B is multiplied by B and C is multiplied by 2

Step-by-step explanation:

Answer: the 100th term of the sequence =-273 (1)

Step-by-step explanation:

Since the first term = 222

and d  (common difference )=-5 Then we are talking about an arithmetic progression

The nth term of an Arithmetic progression is given as

Tn=a + (n - 1)d

Therefore given that n =100

Tn=a + (n - 1)d = 222 +(100-1)-5

222+ (99)-5

222-495=-273

Answer:

-26 is your answer

Step-by-step explanation: 2³ first which = 8 then solve in the parenthesis and all inside parenthesis = -19 so now you have -19+9-4². Now, solve 4² which = 16 so now you have -19+9-16 then solve that and it should give you -26.

Hope this helped you!!!!

Answer:

30

Step-by-step explanation:

Looking at the question we will notice that every 6 that Troy puts together Drake makes 10 so its simple, Troy makes 18 so we divide that by 6 meaning we get 3. We then get 3 and multiply it by 10, Thus 30 shall be our answer.

Answer (assuming it can be in slope-intercept form):

y = x - 5

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], and substitute the x and y values of the given points into it. Then, solve:

[tex]m = \frac{(2)-(1)}{(7)-(6)} \\m = \frac{2-1}{7-6} \\m = \frac{1}{1} \\m = 1[/tex]

2) Now that we know the slope and at least one point the line crosses through, we can write an equation of the line in point-slope form, or [tex]y-y_1 = m (x-x_1)[/tex]. Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.

Since [tex]m[/tex] represents the slope, substitute 1 for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, use any one of the given points (either one is fine, either way the equation will represent the same line) and substitute its x and y values into the equation. (I chose the point (6, 1), as seen below.) Finally, isolate y to put the equation in slope-intercept form.

[tex]y-1 = 1(x-6)\\y -1 = x-6\\y = x -5[/tex]

Answer:

1st answer is 6, 2nd is 5, 3rd is 5

Step-by-step explanation:

3x-2=x+10

3x-x=10+2

2x=12

x=12÷2

x=6

x+4=19-2x

x+2x=19-4

3x=15

x=15÷3

x=5

8z-20=z+15

8z-z=15+20

7z=35

z=35÷7

z=5

plzz mark me as brainliest

Answer:

3x-2=x+10

x=6

x+4=19-2x

x=5

8z-20=z+15

z=5

Step-by-step explanation:

3x-2=x+10

+2 on both sides

3x-2(+2)=x+10(+2)  =>  3x=x+12

subtract x on both sides

3x(-x)=x(-x)+12   =>  2x=12

divide 2 on both sides

2x/2=12/2

= x=6

x+4=19-2x

subtract 4 on both sides

x+4(-4)=19(-4)-2x    =>    x=15-2x

add 2x on both sides    

x(+2x)=15-2x(+2x)     =>    3x=15

divide 3 on both sides

3x/3=15/3

= x=5

8z-20=z+15

subtract z on both sides

8z(-z)-20=z(-z)+15    =>  7z-20=15

add 20 on both sides

7z-20(+20)=15(+20)

7z=35

divide 7 on both sides

7z/7=35/7

= z=5

Answer:

The answer is "(6,3)".

Step-by-step explanation:

In this question, the point is missing if the given point is (-6,-3) so, its solution can be defined as follows:

Throughout this question whenever we reverse the axis to the mirror at the point. The reflection of (-6,-3) is (6,3), which also is the correct value because it changes the coordinates, that's why (6,3) is the correct point.

Answer:

f=4x-148

62 degrees fahrenheit

Step-by-step explanation:

Chirps per minute=148

x=148

x=4f-148

100=4f-148

248=4f

62=f

If snowy tree crickets chirp at 100 chirps per minute, the temperature outside is 62 degrees fahrenheit.

Answer:

55 degrees

Step-by-step explanation:

Complementary angles are two angles that equal 90 degrees together so if one angle is 35 degrees then the other must be able to add towards that to make 90 degrees

90=35+∠2

-35     -35

55=∠2
