Ineed only an expert to answer these questions i will give 20 pts and the brainlest answer if there right

1. 9 more (+9) than two times a number (2x) a number is equal to b. 2X+9

2. Replace the m with 7. Do PEMDAS. 3*7=21. 21-5= 16 so the answer is B.

3. Combine like terms. 1x+10y is the answer so the answer is D.

4. find the GCF of the numbers, which is 8. 8*3=24. 8*8=64 so the answer is C.

5. Property of equalities is two equations that have the same solutions. Just do 22-8, which equals 14. The answer is B.

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°
