Answer:

a₅ = 37

Step-by-step explanation:

The term to term rule ' subtract 3 ' is the common difference d of an arithmetic sequence with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₁₂ = 16, then

a₁ + 11d = 16 ← substitute d = - 3

a₁ + 11(- 3) = 16

a₁ - 33 = 16 ( add 33 to both sides )

a₁ = 49 , then

a₅ = 49 + (4 × - 3) = 49 - 12 = 37

Morgarella [4.7K]

Answer:

Find out the  how much did each roll of crepe paper cost .

To prove

Let us assume that the cost of the  roll of crepe paper be x.

Let us assume that the cost of the balloon be y .

As given

For party decorations, you buy 6 rolls of crepe paper and 20 balloons for $11.90.

Than the equation becomes

6x + 20y = 11.90

As given

After you start decorating, you determine that you need more party decorations.

You buy 2 more rolls of crepe paper and 15 more balloons for $6.05.

Than the equation becomes

2x + 15y = 6.05

Than two equations are

6x + 20y = 11.90 and 2x + 15y = 6.05

Multiply 2x + 15y = 6.05 by 3 and subracted with 6x + 20y = 11.90

6x - 6x + 45y -20y = 18.15 - 11.90

25y = 6.25

y = \frac{6.25}{25}

y = $0.25

Put in the equation 2x + 15y = 6.05

2x + 15 × 0.25 = 6.05

2x = 6.05 - 3.75

2x = 2.3

x = \frac{2.3}{2}

x = $1.15

Therefore the each roll of crepe paper cost is  $1.15 .

adult for every 6 children. One class has 24 children; one has 26 children; and the third has 28 children. Each class has 1 teac
ycow [4]

Answer:

10 adults


Step-by-step explanation:

1 adult per 6 children

there already 1 adult per class so 6 children from each class are covered

24 - 6 = 18

26 - 6 =20

28 - 6 = 22



18 + 20 + 22 =  60

60 ÷ 6 = 10

so 10 more adults are needed

Help me with this geometry
KiRa [710]

Answer:

x= (5X+3) DEGREES = 90 degrees (right angle)

5x=90 degrees - 3 degrees =87 degrees

5x÷5 =87 degrees ÷ 5

x=17.4 degrees

we now know our angles x = 17.4 degrees so we can know substitute into the give formula

wxz=5 (17.4)+ 3

wxz =90 degrees

zxy=we know the size of x

zxy=

8 (17.4)-4

zxy=135.2 degrees
