Answer:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding  

5

to the previous term in the sequence gives the next term. In other words,  

a

n

=

a

1

+

d

(

n

−

1

)

.

Arithmetic Sequence:  

d

=

5

This is the formula of an arithmetic sequence.

a

Mateo has 72 pounds of apples. He needs 34 pounds of apples for each batch of applesauce. How many batches of applesauce can Mat
mr Goodwill [35]

Answer:

  2 batches

Step-by-step explanation:

(72 lb)/(34 lb/bat) = 2 2/17 bat

___

72 ÷ 34 = 2 remainder 4.

Mateo can make 2 full batches, and will have 4 pounds of apples remaining.

The fraction 4/34 can be reduced to 2/17. That is the fraction of a batch that Mateo could make with the extra 4 lbs. of apples.

HELP!!<br> can someone lease help me with #11 and #12
Fiesta28 [93]

11. The two angles are vertical angles, which mean they are equal to each other.

14x - 5 = 13x

Add 5 to both sides:

14x = 13x + 5

Subtract 13x from both sides:

x = 5

12.  The two angles are supplementary and when added together need to equal 180 degrees.

5x -20 + 3x = 180

Combine like terms:

8x -20 = 180

Add 20 to both sides:

8x = 200

Divide both sides by 8:

x = 200 /8

x = 25

One side of triangle is 4 4 times the shortest side. The third side is 23 23 feet more than the shortest side. The perimeter is
jasenka [17]

Answer:

9, 32 and 36

Step-by-step explanation:

The perimeter of a triangle is the sum of all the sides.  Since you know the perimeter and the expressions for each of the sides, you can set up an equation to solve for the variable and find the values of the other sides:

one side: '4 times the shortest side' = 4s

shortest side: 's'

third side: '23 more than the shortest side' = s + 23

perimeter  = 77

Equation:  4s + s + (s + 23) = 77

Combine like terms:  6s + 23 = 77

Subtract 23 from both sides:  6s + 23 - 23 = 77 - 23 or 6s = 54

Divide by 6:  6s/6 = 54/6 or s = 9

one side: 4s = 4(9) = 36

shortest side: s = 9

third side: s + 23 = 9 + 23 = 32
