If 15 cans of food are needed for 7 men for 2 days, then 30 cans of food are needed for 4 men for 7 days.
Assuming that the men eat every day, without skipping a day, then the first part of the sentence is basically saying 15 cans can feed 14 men. There are seven men who can survive off part of the 15 cans on day one, and seven men who can survive off of what's left of the 15 cans on day two. The 15 cans have the potential to feed 14 men in one day basically. Applying this same theory, x number of cans has the potential to feed 28 (that's 4 men for 7 days). If these cans are the same size and are equal in terms of how filling its contents are, then we can set up a proportion.
15/14 = x/28
If 15 cans of food can feed 14 men, then x cans of food can feed 28 men.
Cross Multiply
14x = 420
Divide both sides by 14
x = 30
30 cans of food can feed 4 men for 7 days. Hope this helps!
1.05 x 10^3 : 1 x 10^3 = 1.05 : 1 x 10^3 : 10^3 = 1.05 x 10^0 = 1.05
Rewrite the given equation in slope intercept form:
5 y = 10 – 2 x
y = - 0.4 x + 2
Since the two lines are parallel, therefore they have
similar slope which is – 0.4, so the equation is:
y = - 0.4 x + b
Given that x = 5, y = -4, find for b:
-4 = - 0.4 (5) + b
b = -2
So the answer is:
y = - 0.4 x – 2
or

Answer:
B
Step-by-step explanation:
1. A reflection across the origin has a rule
2. A translation 9 units to the left and 7 units down has a rule
Then the rule for a reflection across the origin followed by a translation 9 units to the left and 7 units down is
This means that the point with coordinates (x,y) has the image with coordinates (x',y')=(-x-9,-y-7).
The answer is $.085. This is the cost of the gasoline per mile. I got the answer through adding all the expenses (insurance, registration, and maintenance) which added up to $1191 and then subtracting it from $1837, which gets me $646. Lastly, I computed for the cost of gasoline per mile through dividing $646 by 7600 miles. I got .085.
