Answer:
x=2
y=7
Step-by-step explanation:
Since we know that the object is a rectangle, we know that the opposite sides are equal to each other. Thus:
9 = y+2
and
2y = 7x
Using algebra we can solve the first equation:
9 = y+2
9-2 = y
7 = y
Now we can use substitution:
2y = 7x
2(7)=7x
14=7x
x=2
Answer:
33
Step-by-step explanation:
3q + 3j
if q= 7 and j = 4
3(7) + 3(4) = 21 + 12 = 33
Answer:
x = 75 m
Step-by-step explanation:
This is a problem of similar triangles solved using proportions.
In similar triangles, corresponding side lengths are proportional.
Here the small and large triangles are similar because the have all three angles congruent.
By proportions, identifying corresponding sides,
x/45 = 50/30
solve for x
x = 45*(50/30) = 75 m
