Answer:
Step-by-step explanation:
Combine like terms, rewrite the equation and perform the operations between the coefficients,
X - y = -5
-y = -x - 5
y = x + 5...slope here is 1. A perpendicular line will have a negative reciprocal slope. All that means is flip ur slope and change the sign. So our perpendicular line will have a slope of -1.
y = mx + b
slope(m) = -1
(4,7)...x = 4 and y = 7
now we sub and find b, the y int
7 = -1(4) + b
7 = -4 + b
7 + 4 = b
11 = b
so ur perpendicular equation is : y = -x + 11 <==
total mass = mass of a bag of candy + mass of a chocolate bar
total mass = 80g +110g = 190g
Answer: 24
8 oz is half a pound because a pound is 16 oz, so if you count how many halves go into 12 lbs you get 24 bags
Since the scale is 1:83, the real airplane is 83 times longer than the model airplane.
real length = 10.5 in * 83 = 871.5 in
Now we convert 871.5 in into ft.
1 ft = 12 in, so 1 in = 1/12 ft
We divide the number of inches by 12 to find the number of feet.
871.5 in = 871.5/12 ft = 72.625 ft
