could someone please check these problems for me? Thank you!

1. -0.7x<-35

x<50

2. Solve by elimination

3x+4y=3

6x+8y=6

answer:0

3. find y intercept to graph

x+5y=10

answer: (0,2)(10,0)

4. use distributive law to solve

7(w-5)=-35

7w-35=-35

if i add 35 to both sides i get 0

5. Simplify

1[-61-(58-85)]

1[-61-(-27)]

1[-61+27]

-61+27

-34
