Ok let's do this*pops knuckles*
let's add the first side
![1 + 2 \times 3 - 18](https://tex.z-dn.net/?f=1%20%2B%202%20%5Ctimes%203%20-%2018)
order of operations demands that we do multiplication first(P.E.M.D.A.S)
so
![2 \times 3 = 6](https://tex.z-dn.net/?f=2%20%5Ctimes%203%20%3D%206)
now we can add the 1 from
![1 + (6) - 18](https://tex.z-dn.net/?f=1%20%2B%20%286%29%20-%2018)
into our six
![6 + 1 = 7](https://tex.z-dn.net/?f=6%20%2B%201%20%3D%207)
now we substract
![(7) - 18 = - 11](https://tex.z-dn.net/?f=%287%29%20-%2018%20%3D%20%20-%2011)
now we have
![- 11 \div 3 + (5(2 + 2))](https://tex.z-dn.net/?f=%20-%2011%20%20%5Cdiv%203%20%2B%20%285%282%20%2B%202%29%29)
now we focus on the
other side
![3 + (5(2 + 2))](https://tex.z-dn.net/?f=3%20%2B%20%285%282%20%2B%202%29%29)
since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.
![(5(2 + 2)) = (((5 \times 2) + (5 \times 2) = 20](https://tex.z-dn.net/?f=%285%282%20%2B%202%29%29%20%3D%20%28%28%285%20%5Ctimes%202%29%20%2B%20%285%20%5Ctimes%202%29%20%3D%2020)
now we have
![3 + 20 = 23](https://tex.z-dn.net/?f=3%20%20%2B%2020%20%3D%2023)
(the three is from the original equation)
now we plug in our final numbers
![- 11 \div 23](https://tex.z-dn.net/?f=%20-%2011%20%5Cdiv%2023)
or
![\frac{ - 11}{23}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%2011%7D%7B23%7D%20)
I hope this helps
We need the following to be true
a+2b = -a
a+4 = 2a - 3b
Let's look at the first equation.
a + 2b = -a
Subtract both sides by a
2b = -2a
b = -a
Substitute b= -a into the second equation
a+4 = 2a + 3a
a + 4 = 5a
4a = 4
a = 1
Just take the negative of that and you get the value of b.
b = -1
Your solution is a=1 and b = -1.
Have an awesome day! :)
It would be 0 because 8 is over 5 so ya
Answer:
I don't know if this is right or not, but here's what I think.
There are 36 butterflies on each flower.
Step-by-step explanation:
<u>Question:</u>
For each 10 flowers, there are <u>36 butterflies resting on the flower</u> with the same number on each flower. How many butterflies are on one flower?
Answer: B
Step-by-step explanation:
The range of a function is the set of all possible values for the function's dependent variable. In this case, that variable is y, so we can look at the graph to observe what possible y-values fit in the range.
There are no y-values below -1 on the chart, and the function goes upwards to infinity, so the correct answer is B, y is greater than or equal to -1.
