Answer:
900 calories
Step-by-step explanation:
First you have to find the unit rate, how many calories are there in ONE cracker? To find that you have to divide 60 ÷ 12 = 5 and to check with the other one, 75 ÷ 15 = 5
So, one cracker is 5 calories. Now, how many calories are in 180 crackers? You multiply, 180 x 5 = 900
That means there are 900 calories in 180 crackers.
Hope that helps and have a great day!
Answer:
y = 4x - 19
Step-by-step explanation:
The line is parallel to the line whose equation is;
y = 4x + 1
Parallel lines have the same slope so the slope of our line is 4.
The line passes through point (5,1)
Slope = change in y ÷ change in x
Taking another point (x,y) on the line,
Slope = 
= 4
y - 1 = 4x - 20
y = 4x - 19
