Irene says the equation 9x+15=3x+15 has no solution because 9x is greater then 3x. is he right yes or no and explain why
Answer:
This equation has one solution, if x = 0
Step-by-step explanation:
Because, you subtract 15 from both sides so: 9x + 15 - 15 = 3x + 15 - 15 which equals: 9x = 3x. if x = 0 this equation is true.
Answer:
X=0
Step-by-step explanation:
If we subtract 15 from both sides, then we can see 9x=3x. If x was 0, then the equation would be 9x0=3x0. Since 0 times anything equals 0, this equation would be true resulting in 0=0.

The anwer pls:Cameron has 2 video game holder stands. Each stand has 2 rows of 20 and 2 rows of 24 games. Find the total number of video games Cameron's stands can hold.
Answer: 176
Step-by-step explanation:
GIven: In each stand,
It has 2 rows of 20 games.
It has 2 rows of 24 games.
Total number of video games in each stand = 2 x 20 + 2x 24
= 40+48
= 88
Since there are 2 identical stands,
then toral video games in 2 stands = 2 (88)= 176
Hence, the total number of video games Cameron's stands can hold= 176.

Anna earns money by walking dogs on Saturdays. Each Saturday she walks 5 dogs for 30 minutes. She charges one
customer $8 because the dog is very large. Each of the other customers pays $6. Which equation could be used to find out
how much money Anna earns each Saturday?
A)
y = 6 + 8
B)
y = 4 x 6 + 8
09
y = 4 * 6-8
D)
y = 5 x 6 + 8
Answer:
y = 4 x 6 + 8
Step-by-step explanation:
the 4 is the amount of dogs that arent big
the is 6 is the amount that she gets for walking the normal sized dogs
the 8 dollars is the amount that she gets for walking the big dog
so you would multiply 4x6 which would give you 24
then add the 8 and you will get 32
so that would mean she gets 32$ every saturday

Answer:1/4
Step-by-step explanation: im sry if im wrong
The probability that both marbles are blue is 9 percent.
It is given that 12 marbles in a bag, four of them are blue and the rest are green.
To find the probability that both marbles are blue.
What is probability?The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
Let both the marble be blue for event A.
P(A)=2C4/2C12 (combination formula)
=6/66
=1/11
≅0.09
=9percent.
So ,the probability that both marbles are blue is 9 percent.

Answer:
[tex]\dfrac{4}{3}[/tex]
Step-by-step explanation:
Number of boxes of paper = 4
Number of printer = 3
We have to find the number of pages in each printer.
Let the number of pages in each box be 1.
Total number of pages in 4 boxes = 4
3 printer will have pages = 4
1 Printer will have pages = [tex]\dfrac{4}{3}[/tex]
Hence, pages each printer will have is equal to [tex]\dfrac{4}{3}[/tex].

The terminal side of θ passes through the point (10, 6). What is the exact value of cos θ in simplified form?
Answer:
[tex]\frac{5\sqrt{34}}{34}[/tex]
Step-by-step explanation:
The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = [tex]\sqrt{a^{2} + b^{2} }[/tex].
In the equation you'd write that as r = [tex]\sqrt{10^{2} + 6^{2}[/tex] which can be simplified to [tex]\sqrt{136[/tex].
You end up with [tex]\frac{10}{\sqrt{136} }[/tex] and you simplify this by doing [tex]\frac{10 }{\sqrt{136} } * \frac{\sqrt{136} }{\sqrt{136} }[/tex], ending with the result of [tex]\frac{5\sqrt{34}}{\sqrt{34} }[/tex].

Describe how probability and odds are related.
Answer: The probability that an event will occur is the fraction of times you expect to see that event in many trials. Probabilities always range between 0 and 1. The odds are defined as the probability that the event will occur divided by the probability that the event will not occur.
