It is 91/32 or 2 27/32 or 2.84375
X=18 and y=10 because they are both 90degree angles therefore all you have to do is solve the equations: 5x=90 and 9y=90.
Answer:
21.62
Step-by-step explanation:
add them together
Answer:
:))
Step-by-step explanation:
Collect like terms, keeping the integer rules in mind
5. 5a + 9b - 3a + 2b + 4a
5a + 4a - 3a + 9b + 2b (REARRANGE, if you find it to help)
6a + 11b
6. 7m + 3n - 8m + 2n + 10m
7m + 10m - 8m + 3n + 2n
9m + 5n
10. 10m²n + 5mn + 9m²n - 2mn
10m²n + 9m²n + 5mn - 2mn
19m²n + 3mn
Try to do the rest on your own :)
