X=5 y=15 (5,15).
This is how you do it:
-4(2x+3y=55): -8x-12y=-220
3(9x+4y=105):27x+12y=315
You add the two new equations together, canceling out the y values, and get the x value. Then, you go back and plug in the x value in the original equation to get the y value.
Answer:
d would be the answer
Step-by-step explanation:
i took the test
Total = 2 + 4 + 10 = 16
Bubble Gums and Tootsie Roll = 2 + 10 = 12
P(Bubble Gums and Tootsie Roll) = 12/16 = 3/4
6 holes in 24 mins.
1 hole in 4 mins.
54 × 4= 216
41 × 4= 164
216-164= 52
So it would take 52 more minutes.
Photomath is the best for fractions, decimals ect. You could also try a scientific calculator.
