Answer:
5 inches is <u>5</u> times as big as 1 inch
P - q = 8.....multiply by -1
2p - q = 19
----------------
-p + q = -8 (result of multiplying by -1)
2p - q = 19
---------------add
p = 11
now we sub 11 in for p in either of the original equations to find q
p - q = 8
11 - q = 8
11 - 8 = q
3 = q
so ur solution is (11,3)
Three consecutive integers that add up to 33 are 2 above and lower than a middle number. This means that the average of these 3 numbers will be the same. Therefore, 33/3=11 as the average. Therefore 11 is the middle number, 9 is 2 below (a consecutive odd integer) and 13 is 2 above (a third consecutive odd integer). Therefore the 3 numbers are 9, 11, and 13.
Let x be the time it takes Elias and Niko to polish the silver working together. If Elias works alone, he could polish all the silver himself in 40 minutes. Then, in 1 minute, he will make
of the total work. If the same analysis is applied Niko, in 1 minute, will make
of the total work.
Working together Elias and Niko will need x minutes to make all the work. Then, in 1 minute, they will make
of the total work. So, the fraction of the total work they make in 1 minute is given by this equation:

Answer:
x=1/3,y=3
Step-by-step explanation:
y=7x+6_____equation1
5x+y=2_____equation2
substitute y into equation 2
5x+7x+6=2
12x+6=2
12x=2-6
12x=-4
x= -1/3
substitute X into equation 1
y=7x+6
y=7(-1/3)+6
y=-7/3+6
y=9/3
y=3
