(17)^ 3 *(289)^ -6 =(17)^ 2m - 1​

m = -4

Step-by-step explanation:

The given expression is :

We need to find the value of m

We know that, 17² = 289

So,

Also,

So,

So, the value of m is equal to -4.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:
