Answer:
x=40°
Step-by-step explanation:
(x-5)+(x+15)=90°
2x+10=90
2x=80
x=40°
Answer:
We just have to solve 3x - 1 = 0 and x + 6 = 0 so the answers are x = 1/3 and x = -6.
Answer:
the answer is 29%
Step-by-step explanation: please mark brainliest
You know there's a 20% chance of wind and no sun.
And there must be a 70% chance of no sun. Since there's a 30% chance of sun
If you divide 0.20 / 0.70 you get .2857 which rounds to 29%.
Answer:
<u>Add 3 to both sides of the equation</u>
Solution:
The first step is to basically realize that all it's asking you to do is to find a way to make the expression on the left (
) into an expression that is a perfect square. So what number should you add to both sides such that 
can be factored into 
? Well, we can approach it like this:
Since can be turned into 
, and our original form was , we quickly realize that 
. From there, we can easily tell that 
Plug this into our last value 
to get 16. Therefore, if we compare this with our original equation again , we notice that 13 + j = 16.
Thus, j = 3 for the last answer.
Add 3 to both sides of the equation.
Note: With more practice, you will quickly gain enough intuition to notice that 
is very close to 
which can be factored into 
. But for now, the solution above will suffice. I hope this helps :))
What we need to find is how many cookies we can make that have 1/12 cups of candy using 4 cups of candy corn.
What we know:
4 cups of candy
1/12 cup per cookie
We need to divide 4 cups of candy corn into groups of 1/12.
4/(1/12)
4/1 x 12/1=4x12=48
So, we have 48 groups of 1/12 cups of candy corn that means we can make 48 cookies each containing 1/12 cup of candy corn.
