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

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
