Answer:
Step-by-step explanation:
One of the more obvious "connections" between linear equations is the presence of the same two variables (e. g., x and y) in these equations.
Assuming that your two equations are distinct (neither is merely a multiple of the other), we can use the "elimination by addition and subtraction" method to eliminate one variable, leaving us with an equation in one variable, solve this 1-variable (e. g., in x) equation, and then use the resulting value in the other equation to find the value of the other variable (e. g., y). By doing this we find a unique solution (a, b) that satisfies both original equations. Not only that, but also this solution (a, b) will also satisfy both of the original linear equations.
I urge you to think about what you mean by "analyze connections."
Ok so 1inch=40cm
2 inches by 1.5
multiply everybody by 40 and make them all centimeters
20*2=80
1.5*40=60
80cm by 60cm
1inch=2.54cm
find how many inches in 1 cm
divide both sides by 2.54
1/2.54inch=1cm
80 by 60 cm
multiply that by 1/2.54 nd find inches iquivlent
80 times 1/2.54=31.4960629921259842519685037008
60 times 1/2.54=23.622047...
ok so
dimentions is 31.4960629921259842519685037008 inches by 23.622047 inches
Wouldn’t it just be (0,0) ?
Answer:
After 5 hours
Step-by-step explanation:
Given that Rachel can make 3 bracelets in an hour.
Let y be the no of bracelets and x no of hours.
Then equation for Rachael would be y = 3x ... i
Oliver is having initially 5 completed bracelets and every hour he would make 2 new bracelets
Hence equation would be
y = 2x+5 ... ii
Our question is why both will be equal
y would be equal in both if 3x=2x+5
Or x=5
After 5 hours form the start, both will have same number of bracelets.
The number of people being served went from 6 to 24, so the serving quadrupled.
So multiply 2.5 by 4 and you get 10 pounds of apples.
