Step-by-step explanation:

Answer:

89,86,83

Step-by-step explanation:

92-80=12

12÷4=3

80+3=83

83+3=86

86+3=89

The complete arithmetic sequence will be: 92, 89, 86, 83, and 80.

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as;

aₙ = a₁ + (n - 1)d

Given; The first term (a₁) is 92 and the fifth term (a₅) is 80.

Then the common difference between the terms will be given as;

a₅ = a₁ + (5 - 1)d

80 = 92 + 4d

-12 = 4d

d = -3

Then the missing terms will be

92, 92 - 3, 92 - 6, 92 - 9, and 92 - 12

92, 89, 86, 83, and 80

Hence, the complete arithmetic sequence will be: 92, 89, 86, 83, and 80.

Answer:

XV < XW < WV

Step-by-step explanation:

The side lengths are proportional to angles they see

The side that sees the largest angle has longest measurement and the one that sees smallest angle would be shortest therefore we can order sides from  shortest to longest like this :

XV < XW < WV

Answer:

4 hours

Step-by-step explanation:

if 1/3 of an hour = 10 miles

You need to get it to 120 miles.

120/10 = 12

And 12 x 1/3 = 4

Answer:

below

Step-by-step explanation:

*Not sure how your teacher wants you to round this, but here is how I do it

All you need to do to find the decimal form of a fraction is to take the numerator and divide it by the denominator :

     2 / 3 = 0.6666666.... and keeps going

              = 0.67

To convert this decimal to percentage just multiply it by 100 :

     0.67 x 100 = 67 %

[2+(12×3÷9)-6]÷4

[2+(36÷9)-6]÷4

[2+(4)-6]÷4

[6-6]÷4

[0]÷4

0

Answer:

Ans: 0

Step-by-step explanation:

[2+(12×3÷9)-6]÷4

= [2+(36÷9)-6]÷4

= [2+4-6]÷4

= [6-6]÷4

= 0÷4

= 0

The GCF of 10 and 6 is 2. May this will help you.

Answer:

Step-by-step explanation:

Answer:

36 tiles

Step-by-step explanation:

Since there is 1 extra tile on each side of the 8x8 pool, we can say that the entire area of the picture is 10x10.

Subtracting 8x8 from 10x10 we get

(10x10) - (8x8) = ?

100 - 64 = 36

36 tiles are around the 8x8 pool

Answer:

17

Step-by-step explanation:

If L and M are parallel then the angles will add up to 180 (a straight line), so:

6x+8+4x+2=180

10x+10=180

10x=170

x=17

Answer:

[tex] \boxed{x = 7} [/tex]

Step-by-step explanation:

Given:

We can illustrate this relationship as:

(2x + 1)

___↑___

| |

A — B — C

|____|___|

↓ ↓

(x + 4) (2x – 10)

_______________________________

When you are given an algebraic expression for the length of a segment, you can solve for that value by knowing that the sum of two segments AB + BC = AC.

Thus:

(x + 4) + (2x – 10) = (2x + 1)

[Regroup terms]

(x + 2x) + (4 – 10) = (2x + 1)

[Simplify]

(3x – 6) = (2x + 1)

[subtract 2x from both sides to isolate the variable]

(3x – 6) – 2x = (2x + 1) – 2x

[Regroup terms]

(3x – 2x) – 6 = (2x – 2x) + 1

x – 6 = 1

[Add 6 to both sides to isolate the constant]

x – 6 + 6 = 1 + 6

[Simplify]

x = 7

Answer:

Cory bought 6.30 gallons of gas at the gas station.

Step-by-step explanation:

total amount = cost of snacks + amount spent on gas

[tex]$\$ 24.00=\$ 6.50+\$ 2.78 \mathrm{~g}$[/tex]

[tex]$\$ 2.78 \mathrm{~g}=\$ 24.00-\$ 6.50$[/tex]

[tex]$\$ 2.78 \mathrm{~g}=\$ 17.50$[/tex]

[tex]$g=\frac{\$ 17.50}{\$ 2.78}$[/tex]
