Answer:
(x, y) = (3, 3)
Step-by-step explanation:
Subtract double the second equation from the first.
(2x +3y) -2(x +y) = (15) -2(6)
y = 3 . . . . . . . . simplify
Use the second equation to find x.
x = 6 -y = 6 -3 = 3
The values of x and y are both 3.
Answer:
0.31
Step-by-step explanation:
So if you divide 31 by 100 all you have to do is move the decimal from right to left the number of zeros you have. Here we have 2 zeros so we move from right to left twice.
0.31
Answer:
3 km
Step-by-step explanation:
Lets say that you flipped the smaller triangle to be facing the same way as the bigger triangle. To find the X side, we need to do 4.5/1.2 = 1.75. which is the difference between the sides. So then we do 1.75 x 0.8 = 3.
Sorry if I couldn't explain well enough, which is not something I'm good at. I hope you get the question right! Glad I could help! :)
Answer:
350 adult tickets were sold
Step-by-step explanation:
Let "a" represent the number of adult tickets sold. Then the number of student tickets is (a+69) and the total number of tickets sold is ...
a + (a+69) = 769
2a = 700 . . . . . . . . subtract 69
a = 350 . . . . . . . . . divide by 2
350 adult tickets were sold.
