Answer:
There were 7 small boxes and 14 large boxes shipped.
Step-by-step explanation:
This problem may be solved by a system of equations:
I am going to say that:
x is the number of small boxes used
y is the number of large boxes used
There were twice as many large boxes shipped as small boxes shipped
This means that y = 2x
Each small box of paper weighs 45 pounds and each large box of paper weighs 80 pounds. The total weight of all boxes was 1435 pounds.
This means that 45x + 80y =1435
So we have to solve the following system:
y=2x
45x + 80y =1435
45x + 80 (2x) = 1435
205x = 1435
x= 1435/205
x=7
y=2x= 2(7) = 14
There were 7 small boxes and 14 large boxes shipped.
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 <==
Yeah it is D i hope this helps u
Hi there!
Let's solve this problem step by step!
The cost of 1 round of golf is $18
and therefore the total cost for all of the tickets is $18 ×
the amount of golf plays, mathematically $18 × g, hence 18g
The membership cost of 1 month is $250
and therefore the total cost for all of the tickets is $250 ×
the amount of months, mathematically $250 × m, hence 250m.
Now we can set up the equation. The only thing we need to do is adding up the individual functions.
Answer:
C = 250m + 18g
