what is x and y? help
​

Answer:

Below.

Step-by-step explanation:

tan(180-ø).tan(90+ø)+xcos(90+ø).(cos90-ø) = sinø(sin180-ø)

xcos(90+ø).(cos90-ø) =  sinø(sin180-ø) -  tan(180-ø).tan(90+ø)

x =  (sinø(sin180-ø) -  tan(180-ø).tan(90+ø)) / cos(90+ø).(cos90-ø)

x = - (sin^2ø + tanø(tan(90+ø)) / cos^2ø

Answer: 5 lattes

Step-by-step explanation: Our equation is 20 − 3.5x = 2.5, which means x = 5 lattes.

Answer:

Step-by-step explanation:

y=3.5x (cost function where y is cost and x is the number of lattes)

20-2.5=3.5x

17.5=3.5x

5=x

So she bought 5 lattes.

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=-3x+2

Step-by-step explanation:

y-y1=m(x-x1)

y-(-4)=-3(x-2)

y+4=-3x+6

y=-3x+6-4

y=-3x+2

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

Answer:

[tex](a)[/tex] [tex]\frac{30}{5} = 6[/tex] and [tex]\frac{60}{10} = 6[/tex]

[tex](b)[/tex] [tex]\frac{24}{3} = 8[/tex] and [tex]\frac{96}{12} = 8[/tex]

[tex](c)[/tex] [tex]\frac{112}{8} = 14[/tex] and [tex]\frac{28}{2} = 14[/tex]

Step-by-step explanation:

Given

[tex](a)\ 15 * \frac{2}{5} = 6[/tex]

[tex](b)\ 6 * \frac{4}{3} = 8[/tex]

[tex](c)\ 16 * \frac{7}{8} = 14[/tex]

Required

Write 2 division equations

[tex](a)\ 15 * \frac{2}{5} = 6[/tex]

Express 15 as 15/1

[tex]\frac{15}{1} * \frac{2}{5} = 6[/tex]

Multiply numerator and denominator

[tex]\frac{30}{5} = 6[/tex] --- This is (1)

Multiply the fraction by a common term (e.g. 2)

So, we have:

[tex]\frac{30*2}{5*2} = 6[/tex]

[tex]\frac{60}{10} = 6[/tex] ---- (2)

[tex](b)\ 6 * \frac{4}{3} = 8[/tex]

Express 6 as 6/1

[tex]\frac{6}{1} * \frac{4}{3} = 8[/tex]

Multiply numerator and denominator

[tex]\frac{24}{3} = 8[/tex] --- This is (1)

Multiply the fraction by a common term (e.g. 4)

So, we have:

[tex]\frac{24*4}{3*4} = 8[/tex]

[tex]\frac{96}{12} = 8[/tex] ---- (2)

[tex](c)\ 16 * \frac{7}{8} = 14[/tex]

Express 16 as 16/1

[tex]\frac{16}{1} * \frac{7}{8} = 14[/tex]

Multiply

[tex]\frac{112}{8} = 14[/tex] ---- This is (1)

Divide the fraction by a common term (e.g. 4)

[tex]\frac{112/4}{8/4} = 14[/tex]

[tex]\frac{28}{2} = 14[/tex]

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:

x+y=10

y=10-x

To  isolate y, you subtract x on both sides.

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:

1. g = 4

2. g = 19

3. g = 39

4. g = 59

Step-by-step explanation:

Answer:

4,19,39,59

Step-by-step explanation:

it’s actually pretty simple.

for the first one you take 1 and plug it into n which looks like:

g=5(1)-1

then find yourself answer:

5(1)= 5

5-1=4

answer is 4

then you plug your four into n:

5(4)-1= 19

answer is 19

then you plug your 8 into n:

5(8)-1=39

answer is 39

then you plug your 12 into n

5(12)-1= 59

answer 59

by dojng lenght into breadth

Answer:

40

Step-by-step explanation:

Try to get the variable alone by dividing 5/8 on both sides of the equations.

That cancels out the 5/8 on the left leaving u and the 25 on the right turns into 40. It turns into 40 because 25 divided by 5/8 equals 40.

Answer:

40

Step-by-step explanation:

Multiply both sides by 8/5

Complete Question

Mis. Jackson wants to rent a van for a week it will cost a weekly fee plus 0.20 per mile driven let m equal the number of miles Ms. Jackson drives during the week write an algebraic expression that shows a week rent Jackson will pay for the van for the week

Answer:

A = w + 0.20m

Step-by-step explanation:

Step 1

We find the equation for the total amount spent in a week

The total amount to rent the van in a week = A

Weekly fee = w

Number of miles = m

Therefore, thw algebraic expression that shows a week rent Jackson will pay for the van for the week is

A = w + 0.20m

Answer:

The largest possible value is 23

The smallest is 7

Step-by-step explanation:

To get the length of JL, we use the triangle inequality theorem

The theorem is that the sum of the measure of any two sides of a triangle must be greater than the measure of the third side of the triangle for the triangle to exist

With respect to this, 9 + 15 must be greater than JL

since JL is an integer ( integers are whole numbers); we have the following

9 + 15 = 24

JL is less than 24; so the nearest integer closest to 24 is 23

Now, let us get the smallest possible value

For the smallest possible value;

Let us call that x

9 + x > 15

15 + x > 9

From the first inequality;

x > 15-9

x > 6

The smallest integer greater than is 7

So the smallest possible value for JL is 7 and the largest is 23

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!!!!

Explanation:

4²+4²≠8²

(4+4)²=8²

If you use PEMDAS you can find that 4²+4²=32 not 8² which equals 64

You can also find that (4+4)²=(8)²

Answer:

b and d

Step-by-step explanation:

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
