The answer to this question of yours is B
Answer:
32
Step-by-step explanation:
write the equation
0.3y + y/z=
Then you fill in what you know
0.3(10) + 10/5=
then we multiply/divide
30 + 10/5
then we continue to multiply/divide untill there is nothing to multiply/divide anymore
30+2
then we add/subtract
32
Our answer is 32
Answer:
(x, y) = (2, 9)
Step-by-step explanation:
For the triangles to be congruent, the hypotenuses must be the same length:
y = x + 7
and the marked leg must be the same length in each triangle:
y -3 = 4x -2
These are two equations in two unknowns (a "system" of equations) that can be solved in any of the usual ways. Since the first equation gives an expression for y, it is convenient to substitute that into the second equation:
(x +7) -3 = 4x -2
x +4 = 4x -2 . . . . . . collect terms
x +6 = 4x . . . . . . . . .add 2
6 = 3x . . . . . . . . . . . subtract x
2 = x . . . . . . . . . . . . divide by 3
y = 2 + 7 = 9 . . . . . .substitute for x in the first equation
The values you're looking for are x = 2, y = 9.
It doesn't matter if there is 0, you still flip the inequality symbol.
