Answer:
Step-by-step explanation:
Well, this is a dumb problem... they're trying to trick you with the answers. :(
Okay, so what you're going to do is multiply the whole numbers by 1 put into the fractions.
Juan= 4 1/6--- 4 * 6/6 = 24/6
24/6 + 1/6 = 25/6
Antonio= 3 2/3 ---- 3 * 3/3 = 9/3
9/3 + 2/3 = 11/3
They changed the names around in the answers- Pay attention to who is associated to each fraction.
The right answer is D. Good luck... I hate it when problems try to trick you like that.
Answer: x= -9/19
Step-by-step explanation:
5x+18/8=x/4
5x+ 9/4=x/4
5x+9/4-9/4=x/4-9/4
5x= x-9/4
5x(4)=x-9/4(4)
20x=x-9
20x-x=x-9-x
19x=-9
19x/19=-9/19
x=-9/19
Answer:
17.6%
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
this can be solved using simultaneous equation
2a + 3b = 19 equation 1
1a + 4b = 17 equation 2
Multiply equation 2 by 2
2a + 8b = 34 equation 3
Subtract equation 1 from 3
5b = 15
b = 3
Substitute for b in equation 1
2a + 3(3) = 19
2a = 9 = 19
2a = 10
a = 5
