Question

Substitute the value for the variable, and state in a complete sentence whether the resulting number sentence is true or false. If true, find a value that would result in a false number sentence. If false, find a value that would result in a true number sentence. 1. 15a ≥ 75. Substitute 5 for a.

Answer 1

Explanation:

`15a\geq 75\\15(5)\geq75\\75\geq75\\True`

If we substituted 1 for a then:

`15a\geq75\\15(1)\geq75\\15\geq75\\False`
