Answer:
2/ x = +-2
3/ n = +-3
Step-by-step explanation:
Replace the informations you don't know with letters.
x = number of bags
y = number of sandwiches
7x + 3y = 22
3x + y = 8
Then solve the equations.
First, isolate the y in the second one like this :
y = 8 - 3x
then replace the y in the first equation with its worth from the second equation :
7x + 3(8 - 3x) = 22
solve for x, then replace the value in the equations to get the value of y
Answer:
The sum of the two smaller sides is supposed to be greater than the third side. According to online, "as long as the sum of any two of those measurements is greater than the third measurement, the three 'sides' will fit together to make a triangle."
Since the smaller sides only add up to the third length this wouldn't be enough to create a triangle. Therefore the final answer is no.
Answer:
The population of both Midwest and West will be equal after 11 years and 8 months.
Step-by-step explanation:
It is provided that in 1990 the population of Midwest was 60 million and that of West was 53 million.
The average increase in population of Midwest areas is 0.4 million/year and in case of west areas it is 1 million/year.
The expression representing the population of Midwest in <em>x</em> years is:
The expression representing the population of West in <em>x</em> years is:
Compute the value of <em>x</em> such that the population of both Midwest and West are same as follows:
So after years or 11 years and 8 months the population of both Midwest and West will be equal.
