keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above
so we're really looking for the equation of a line with a slope of 2 and that it passes through (4 , 1)
kinda twins.
Answer:
The required system of equations is:
Step-by-step explanation:
First of all, the variables have to be selected to represent the quantities.
Let m be the number of male friends and let f be the number of female friends.
Then according to first statement "John has 30 friends"
And according to second statement "amount of male friends is 4 more than the number of female friends."
Hence the required system of equations is:
Ok and what is the question
X = large boxes and y = small boxes
x + y = 70.....x = 70 - y
60x + 65y = 4300
60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs
x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
