Answer:
8.3
Step-by-step explanation:
<u>do whats in the brackets first.</u>
13-17-1.3= -5.3
<u>rewrite the equation</u>
3-7+2-[-5.3]+5
3-7+2= -2
<u>rewrite the equation</u>
-2-[-5.3]+5
when 2 negative signs are together u change it to a positive sign.
<u>rewrite the equation</u>
-2+5.3+5
-2+5.3= 3.3
<u>rewrite the equation</u>
3.3+5=8.3

Answer:
30 miles apart.
Step-by-step explanation:
The scale for the map is 1 inch represents a distance of 10 miles.
That is 1 inch : 10 miles.
We want to find the number of miles two towns are apart, if they are 3 miles apart on the map.
We just have to multiply each term in the ratio by 10 to get:
3 inches: 30 miles
Therefore the two towns will be 30 miles apart.
Let's say that x represents hours that Elizabeth volunteers over 1 week. Katie volunteers x+3 and Siobhan x-1 hours per week. The equation that arises from condition in text is:
3*(x+3) = 3*(x + x-1)
x+3 = 2*x - 1
2*x - x= 3+1
x=4.
Elizabeth volunteers 7 hours
Katie volunteers 4 hours
Siobhan volunteers 3 hours
