Answer:
X= 17
Step-by-step explanation:
In the picture above , you see that
BAE =~ DAE
So , just substitute the equation of each other and solve for x.
That's it.
Answer:
For this scenario, I used the elimination method. Organize the equations, so it's easier to subtract from each other. My x-variable will represent the number of hot dogs and my y-variable will represent the number of sodas.
3x+2y=213
x + y =87
We need to make sure one of the monomials are alike in each equation, so we can eliminate a variable. Distribute 3 to each number/variable in the second equation.
3x+2y=213
3(x+y=87) --> 3x+3y=261
Now we can eliminate x.
3x+2y=213
- 3x+3y=261
----------------------
-y=-48
Divide -1 to both sides to get y=48. So, you sold 48 cans of soda. Now, we can find the number of hot dogs by substituting 48 into the second equation to get x+48=87. Subtract 48 to both sides to result with x=39. So, you sold 39 hot dogs.
Answer:
The answer is 13.57m^2

On Edmentum I got it right.
Answers:
- A in the upper left
- D in the upper right
- B in the lower left
- C in the lower right
==================================================
Explanation:
Segments AB and AD have the letter A in common. This must mean they intersect at point A; i.e. they both have point A on their segment. Therefore, point A is in the upper left corner.
This logic is used to determine the other three corner points as well. The upper right corner is point D since AD and DC have D in common. The same goes for the bottom points as well.
Answer:
To do this, you wold need to know the percent error formula.
Percent Error = (Actual value - Expected Value)/Expected Value x 100
Percent Error = (388 - 400)/400 x 100
P.E = (-12)/400 x 100
-0.03 x 100
-3%
(It could possibly positive, if they don't take negative)
Hope this helps!
