Answer:
The given set of equation are:    x+ (-45) ≤  35  ,  x - (-45) ≥  35 
For the given equality to be true, x  ≤ 35
Step-by-step explanation:
Here, given the first number = x
Second number  = -45
Now, Sum of x  and - 45 is at most 35.
⇒  x+ (-45) ≤  35
Also,  The difference of x and -45 is at least 35.
⇒  x - (-45) ≥  35 
Now, simplifying the given set of equations:
x  - 45  ≤  35   ⇒    -x - (-45) >   - 35   ( as 3  <  4  ⇒ -3  > -4)
or, -x  + 45  >  - 35
 and second equation is x  + 45 ≥  35 
Now, solving both the equations by not taking sign of inequality in to the consideration, we get
x - 45  = 35
x + 45 = 35  
Adding both equations,we get:   ⇒ 2x = 70
                                                           or x = 35
Hence for the given equality to be true, x  ≤ 35

Answer:
x=2 
Step-by-step explanation:
In order to solve this problem, you need to find the scale factor. This is done through cross multiplying proportions. In this instance, you have to cross multiply x/4 by 3.5/7. When you multiply x and 7, you get 7x. When you multiply 3.5 and 4, you get 14. Simplify by isolating the variable, and you get 2.
