Answer:
Calculating the Actual Distance using the Scale
If the scale is 1 : x, then multiply the map distance by x to calculate the actual distance.
Step-by-step explanation:
The correct question is
<span>Keiko sold 3 less than three-fourths of his sister’s sales. Which expression represents what Keiko sold?
Let
S----------------> </span><span>the amount that Keiko's Sister sold
</span>K----------------> the amount that Keiko sold
we know that
Keiko sold 3 less than three-fourths of his sister’s sales
K=(3/4)*S-3
the answer is
K=(3/4)*S-3
Answer:
y = 6/5x - 2
Step-by-step explanation:
y = mx + b
plug in values
4 = (6/5)(5) + b
simplify
4 = 6 + b
subtract 6 from both sides
-2 = b
y = 6/5x - 2
<span>Yes, she is reasoning correct, because:
6 1/4 and 2 3/4 are mixed fractions and you can substract them as it shown below:
1. You must substract the fractional parts (</span>which are: 1/4 and 3/4) of the mixed fractions. You can notice that the have the same denominator "4", so you only need write this denominaro and substract the numerators:
= (1-3)/4=-2/4
When you simplify the result, you obtain:
=-1/2
Now, you must sum the integer parts:
6-2=4
Finally, you obtain:
4 -1/2
