1) Find the Greatest Common Factor (GCF).
1 What is the largest number that divides evenly into 12 and 10?
It is 2.
2 What is the highest degree of that divides evenly into 12and 10?
It is 1, since x is not in every term.
3 Multiplying the results above,
The GCF is 22.
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

Step-by-step explanation:
With the inequality given, y ≤ -1, solutions are -1 and all numbers less than -1. We will check all the options to see which is not a solution.
a) -3 ✓
-> This is not our answer. -3 is less than -1.
b) -1 ✓
-> This is not our answer. -1 is equal to -1.
c) -6 ✓
-> This is not our answer. -6 is less than -1.
d) 0 ✗
-> This is our answer! 0 is not less than -1.

find the volume of the cubes or rectangular prisms in cubic centimeters.
Answer:
Cube with a side length of 2/5 cm: 8/125 cm^3
Rectangular prism with a length, width, and height of 3/5 cm, 4/5 cm, and 3/5 cm, respectively: 36/125cm^3
Rectangular prism with a length, width, and height of 1/5 cm, 2/5 cm, and 3/5 cm, respectively: 6/125 cm^3.
Cube with a side length of 1/5 cm: 1/125 cm^3
Step-by-step explanation:
For the first one, cubes have equal sides, we would do 2/5*2/5*2/5, which is 8/125 cm^3.
Next we have a rectangular prism. For this, we will just multiply all of the sides with each other which is 3/5*4/5*3/5 which is 36/125 cm^3
Now we have another rectangular prism. Again, we will multiple all of the sides with one another: 1/5*2/5*3/5, which is 6/125 cm^3.
Lastly, there is a cube with a side length of 1/5 cm. We know that cubes have equal sides, so it would be 1/5*1/5*1/5, which is 1/125 cm^3.

Give the probability as a percent, rounded to the nearest whole number.P(at least three tails) =
Answer:
Sample Space

Harry and Gwen ride in a bicycle race. Harry clocks 102.62 meters per minute, and Gwen clocks 101.94 meters per minute. What is the difference in their cycling speeds?
best answer will get brainliest
Answer:
0.68 meters per minute
Step-by-step explanation:
102.62 - 101.94 = 0.68, so Harry is 0.68 meters per minute faster than Gwen.
Answer:
0.68 m/min.
Step-by-step explanation:
Given :
⇒ Harry's speed = 102.62 m/min.
⇒ Gwen's speed = 101.94 m/min.
===============================================================
Solving :
⇒ Difference = Harry's speed - Gwen's speed
⇒ Difference = 102.62 - 101.94
⇒ Difference = 0.68 m/min.

how to understand next steps what will be anyone give me explains
Step-by-step explanation:
remember a few things :
a × -1 = -a
-a × -1 = a
-1 × -1 = 1
1 × a = a
therefore,
-1 × -1 × a = 1 × a = a
and finally
c × (a + b) = c×a + c×b
so, we can say
(1 - 5) = -1 × -1 × (1 - 5) =
= -1 × (-1×1 + -1×-5) = -1 × (-1 + 5) =
= -1 × (5 - 1) = -(5 - 1)
Franklin has delivered 26 newspapers and

Michael has delivered 5 newspapers and can
deliver 12 newspapers in an hour. How
many hours (h) will Michael take to deliver
as many newspapers (n) as Franklin?
n = 9h+26
n = 12h + 5
[?] hours
Using linear functions, it is found that it will take 7 hours for Michael to deliver as many newspapers as Franklin.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.The linear functions that give the amounts for Franklin and Michael after h hours are given by:
F(h) = 26 + 9h.M(h) = 5 + 12h.They will be equal when:
F(h) = M(h)
Hence:
26 + 9h = 5 + 12h
3h = 21
h = 7

On the first day of a song release, it had 20 million streams. If the number of streams increases by 10% per day, how many streams will there be on the seventh day
Answer:
35.4 million
Step-by-step explanation:
We assume the description "increases by 10% per day" means the base of the percentage is the previous day's number of streams. Then the sequence of streams on consecutive days is a geometric sequence with a first term of 20 million and a common ratio of (1 +10%) = 1.10.
__
streams on day nThe n-th term of a geometric sequence is ...
an = a1×r^(n-1) . . . . . where a1 is the first term, and r is the common ratio
The sequence of streams on consecutive days is then ...
an = 20×1.10^(n-1) . . . . millions of streams on day n
seventh dayFor n = 7, the number of streams is ...
a7 = 20×1.10^(7 -1) ≈ 35.4 . . . . million streams
There will be about 35.4 million streams on the seventh day.

Step-by-step explanation:
We can add these 2 equations together to eliminate [tex]x[/tex] from the equation, leaving us to solve for [tex]y[/tex].
[tex](4x+8y) + (-4x+y) = (40) + (14)\\9y = 54\\\boxed{y = 6}[/tex]
Now we can solve for [tex]x[/tex] through substituting [tex]y[/tex].
[tex]4x+8y=40\\4x+8(6)=40\\4x+48=40\\4x=-8\\\boxed{x=-2}[/tex]
We can check our answers by substituting [tex]x[/tex] and [tex]y[/tex] into one of the equations and seeing if the equation is true.

Match the graph to the correct inequality
X≥-3
X<-3
X≤ 3
X> -3
Answer: Choice A) x ≥ -3
Reason:
The graph has a closed filled in circle at -3, which means we include this value. So we'll have "or equal to" as part of the inequality sign.
We'll also have "greater than" because we're shading to the right.
Hence, we have "greater than or equal to".
Put another way, x = -3 or x > -3 are two possibilities.
If the endpoint at -3 was an open hole, then we'd exclude the endpoint and go for x > -3 instead of x ≥ -3
Answer:
X≥-3
Step-by-step explanation:
Inequalities represent a range of values, rather than a single value.
Let us consider the inequality
x > - 3
This would mean can be any value greater than -3, not including -3.
This is represented by a line starting from -3 and extending indefinitely (marked by an arrow head). Note that at -3, there is a small empty circle which represents that -3 is not included.
In case the inequality was
x > -3
It would mean that -3 has also been included.
In case you can't draw on the number line, you can also show the range just above the number.
