Answer:
Mr Batista should bring more 82 cups.
Step-by-step explanation:
- there are 36 cups in 1 package.
- for 12 packages: [ 12 * 36 ] = 432 cups - this many cups he brought.
solve:
→ 514 - 36(12)
→ 514 - 432
→ 82
He needs more 82 cups and did not bring enough.
Answer:
x = 5/2, y = -1
x*y = 5/2*-1 = -5/2
Step-by-step explanation:
First we solve the system
2x-5y = 10
x = 5 + 5y/2
4x + 3y = 7
4(5 + 5y/2) + 3y = 7
20 +10y + 3y = 7
-13 = 13y
y = -1
Now go back to the other equation
2x - 5y = 10
2x - 5(-1) = 10
2x + 5 = 10
2x = 5
x = 5/2
Now we multiply x and y together
Answer:
B
Step-by-step explanation:
This is because to find the angle you must add up the other two angles.
