Question

1. Five times a whole number x is subtracted from 62 The result is less than 40
Find the three lowest values
2. if 7.3 is subtracted from Y the results is less than 3,4 find the range of value of Y
3. solve the following equation
a.4b= 3 (3b+15)
b. 5( a+2)=4(a - 1)​

Answer 1

Answer:

Step-by-step explanation:

1.  Symbolically, we get:  62 - 5x < 40

2.  y - 7.3 < 3.4.  Solve for y by adding 7.3 to both sides, obtaining:

     y < 10.7    This is both the 'range' and the 'solution'

3a)      4b =  9b + 45, or -5b = 45, or b = -9

3b)      5a + 10 = 4a - 4

Combining like terms results in a = -14
