Kwame fills a bird feeder with seeds. As
birds visit the feeder, the height of the
seeds changes from 13.6 cm to 11.1 cm
over a period of 6 1/4 hours. What is the
average change in the height of the seeds
each hour?
Answer:
Step-by-step explanation:
Givens
Time = 6.25 hours
distance = 13.6 cm - 11.1 cm = 2.5 cm
Formula
rate = distance / time
Solution
rate = 2.5 / 6.25
rate = 0.4 cm/hour
What is the description of the pattern in the sequence?
5, 10, 20, 40, 80,...
The pattern is to multiply by 2.
The pattern is to add 2.
The pattern is to add 5.
The pattern is to multiply by 5.
Answer:
It is to multiply by 2Step-by-step explanation:
Solve 2(x + 1) = 2x + 5. (1 point)
1) Expand.
2x+2=2x+5
2) Cancel 2x on both sides.
2=52=5
3) Since 2=52=5 is false, there is no solution.
No Solution
Therefore, this equation has no solutions.

Round to the tens place to estimate the answer.
172 x 18 =
Answer:
3400
Step-by-step explanation:
When you round to the tens place you look at the number in the ones place. If it is 4 or less then you keep the tens place the same. If it's 5 or more then you round the tens place up one. Then you make the ones digit a 0.
Since there is a 2 in the ones place in 172, you keep the tens digit the same (170).
Since there is an 8 in the ones place in 18, you round the tens digit up one (20).
Now you multiply.
170×20=3400
I hope that made sense.

Answer:
E, D, F
Step-by-step explanation:
One complete tenths block would represent 1 which is a whole number. In the problem, two of the tenths squares are filled in which means that that part is equal to 2. In the third block, that represents 4/10 or 0.4. Putting them together would equal 24/10, 2 4/10, and 2.4
2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5

Graph the relation. Is the relation a function? Why or why not?
I NEED HELP!!!! PLEASE HELP
IT'S NOT A OR B
{(–5, 6), (–2, 3), (3, 2), (6, 4)}
No; a domain value has two range values.
No; a range value has two domain values.
Yes; there is only one range value for each domain value.
Yes; there is only one domain value for each range value.
Answer:
The relation is a function.
To analyze if the relationship shown is a function, you must observe that each value of the domain has a single value of the range assigned. For the given points {(-5, 6), (-2, 3), (3, 2), (6, 4)} this requirement is satisfied. Therefore, the relationship is a function.
Step-by-step explanation:
Since there is one value of y for every value of x in ( − 5 , 6 ) , ( − 2 , 3 ), ( 3 , 2 ), ( 6 , 4 ) , this relation is a function.
The relation is a function.
