Step-by-step explanation:

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.

5

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:

x+y=10

y=10-x

To  isolate y, you subtract x on both sides.

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:

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

Step-by-step explanation:

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:

2/3

Step-by-step explanation:

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?

1 decametre = 10 metres

Hence,

10 meters = 6 pieces of ribbon

1 meter = x pieces

Cross Multiply

10x = 6

x = 6/10

x = 2/3 (1 meter pieces of ribbon)

Answer:

what is the question or whatever

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]

Answer:

[tex]\sqrt{8x^{2} }[/tex]+5-3 = 8.12

8.12 rounded to nears whole number is 8

therefore 8.12 rounded down to three decimal places is 8.1

Therefore your answer would be 8.1

If it wont let you add a decimal your answer would also be 8

Hope this helps! :)

Answer:

1. 8x + 3y - x - 2y

= 8x - x + 3y - 2y

= 7x + y

2. 3n - 7n - 2n + x + 8x

= 3n - 9n + 9x

= - 6n + 9x

3. 2r - 5n + 9y - 3r + n

= 2r - 3r - 5n + n + 9y

= -r - 4n + 9y

4. 12y - 6x + 5y - 3n

= 12y + 5y - 6x - 3n

= 17y - 9n

5. - 13n + 4n - r

= -9n - r

6. 7xy - 8x + 6xy - y

= 7xy + 6xy - 8x - y

= 13xy - 8x - y

7. - 14r - 10n - 3r - 9n

= -14r - 3r - 10n - 9n

= - 17r - 19n

8. 6r + 9r - 2r - 13n

= 6r + 7r - 13n

= 13r - 13n

9. n + r + x - 3x +4r

= n + r + 4r + x - 3x

= n + 5r - 2x

10. 15y - 7x + 9z + 4z - 3x

= 15y - 7x - 3x + 9z + 4z

= 15y - 10x + 13z
