The two expressions are equivalent because they have the same value regardless of the number of substituted in for y
Step-by-step explanation:
Since AC=BE & DE=DC
then measure angle <CAD=<EBD =X
Then< DAB =90-x
And <ABD= 90-X
then measure angle 1= measure angle 2
Sum is used for addition so the answer would be:
D. f+6
Answer:
343
Step-by-step explanation:
if you have a cube, then the volume is one of the sides cubed, or to the third power. 7^3 can be represented as 7*7*7, or 7x7x7, which is 343.

Hi there!
To solve this problem, we need to set up two equations and use the system of equations to solve.
Let x be the first number.
Let y be the second number.
(x + y) ÷ 2 = 34
x = 3y
Now, we can use substitution to solve.
(3y + y) ÷ 2 = 34
4y ÷ 2 = 34
2y = 34
y = 17
Now, we plug the value of y in the equation to solve for x.
x = 3*17
x = 51
Hope this helps!
