Answer:
slope = 5
Step-by-step explanation:
To calculate the slope m use the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (2, 8) ← ordered pairs from the table
m =
= 5
<span>The answer is 60. Let x be the number we are looking for. So x is 100% and we know that 15 is 25%. Make a proportion: x : 100% = 15 : 25%. Cross the products: x * 25% = 15 * 100%. x * 25% = 1500%. x = 1500% : 25%. x = 60. Thus, 60 is 100%, and 15 is 25% of 60. </span>
320%
= 320/100
= (320/20) / (100/20)
= 16/5
= (15+1)/ 5
= 15/5+ 1/5
= 3+ 1/5
= 3 1/5
The final answer is 3 1/5~
