Answer:
x = -6
Step-by-step explanation:
Answer:
140
Step-by-step explanation:
Rewording the problem will make it easier to write the equation you need to solve this. Think of it in simpler terms: "7 is 5% of how many?". "7" is just a 7; the word "is" means =; "5%" is expressed as its decimal equivalency (.05); the word "of" means to multiply; and "how many" is our unknown (x). Putting that all together in one equation looks like this:
7 = .05x
Solve for x by dividing both sides by .05 to see that
x = 140
Answer:
13
Step-by-step explanation:
add 3/4 and 3/4 to get 6/4 then get 1/2 times the bottom and the top but 2 to get 2/4 so then do 6/4 - 2/4 to get 4/4 or 1
add 10,8 to get 18 then subtract 6 to get 12 then all the 1 and you get your answer. Hope this helped
Answer: 20, 70, 90
====================================================
Work Shown:
Let x be some positive real number.
Multiply each part of the given ratio by x to get 2x:7x:9x
So we have the three angles 2x, 7x, and 9x.
For any triangle, the three angles must add to 180
2x+7x+9x = 180
18x = 180
x = 180/18
x = 10
This leads to
- 2x = 2*10 = 20
- 7x = 7*10 = 70
- 9x = 9*10 = 90
The three angles of this triangle are: 20, 70, 90
This is a right triangle due to the 90 degree angle.
X= 20
4X= 100
