Lily cleans 3 houses in 7.5 hours. If she works 8-hour days for 7 days (with no breaks), how many houses could she clean?

Step-by-step explanation:

T3=8

8=a+2d

where a is first term ,d is common ratio

8=a+2(2)

8=a+4

a=8-4

a=4

first term T1 is 4

T2=a+d

T2=4+2

T2=6

T4=a+3d

T4=4+3(2)

T4=4+6

T4=10

T5=a+4d

T5=2+4(2)

T5=4+8

T5=12

4,6,8,10,12

Answer:

1. 8x2 - 7x + 4x3 - 2-3x2 + 9x - 4 = 16+2x

Step-by-step explanation:

1. Multiply all the multiplication problems (should look like this --> 16-7x+12-2-6+9x-4)

2. Calculate the sum or difference (should end up looking like this --> 16-7x+9x) and then into this (16 +2x)

Bringing us to the answer → 16 + 2x!

Step-by-step explanation:

Answer:

f(2b) = -4b + 4

Step-by-step explanation:

Step 1: Define

f(x) = -2x + 4

f(2b) is x = 2b

Step 2: Substitute and Evaluate

f(2b) = -2(2b) + 4

f(2b) = -4b + 4

Answer:

[tex]d=5[/tex]

Step-by-step explanation:

Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d=\sqrt{(7-3)^2+(7-4)^2}[/tex]

[tex]d=\sqrt{(4)^2+(3)^2}[/tex]

[tex]d=\sqrt{16+9}[/tex]

[tex]d=\sqrt{25}[/tex]

[tex]d=5[/tex]

Answer:

f=-9

Step-by-step explanation:

Answer:

 x = 45

Step-by-step explanation:

AB // CD,

∠AB0 + ∠COB = 180  {Co interior angles}

   75 + ∠COB = 180

             ∠COB = 180 - 75 = 105

∠DOE =∠COB   {Vertically opposite angles}

∠DOE = 105

In ΔDOE,

x + 30 + 105 = 180    {angle sum property of triangle}

      x + 135 = 180

                x = 180 - 135

                x = 45

According to the information we can infer that the number is 16. So, 6 - 16 is 10.

Let's assume the number is represented by 'x'.

According to the given information, six less than a number is equal to ten. This can be expressed as:

To find the value of 'x', we can add 6 to both sides of the equation:

This simplifies to:

According to the information we can conclude that the number is 16. So, 6 - 16 is 10.

Answer: Y=7

Step-by-step explanation: if you have to find y then it’s

5y-28=7

   +28+=+28 adding 28 to both sides to have y by itself -28+28=0 & 28+7=35

5y=35 then you divide by 5 on both sides

So it’s y= 7

Answer:

2

Step-by-step explanation:

When you plug in 3 for the value of x you get the equation: 4(3)-2/5 (being divided by 5)

Now we solve the top and the bottom of the fraction.

4×3=12

12-2=10

Answer:

B

Step-by-step explanation:

The numbers in the other functions are less than one which means that they are decreasing.  

well, 6.2% of 4,300 can't be over half. she has made a calculation error, and the real answer is (this is where the mistake was made) 4,300 * 0.062 (not 6.2, because percents are always divided by 100 to make them into a usable number), which is equal to $266.60.

Step-by-step explanation:

Answer:

15,20,25,30

Step-by-step explanation:

f (n) = 5 (n + 2)

Let n=1

f (1) = 5 (1 + 2)

     = 5(3) = 15

Let n=2

f (2) = 5 (2 + 2)

     = 5(4) = 20

Let  n=3

f (3) = 5 (3 + 2)

     = 5(5) = 25

Let n=4

f (4) = 5 (4 + 2)

     = 5(6)=30

Answer:

15, 20, 25, 30

Step-by-step explanation:

To calculate the value of a term, you plug in the term value into the equation, which, in this case, means replacing the n with the term number.

Term 1:

5 (1 + 2)

5 (3)

15

Term 2:

5 (2 + 2)

5 (4)
