Answer:
Step-by-step explanation:
1) Number of white chocolate bars = x
Number of dark chocolate bars = y
Total bars = 15
x + y = 15 --------------(I)
Total cost = Php. 340
20x + 25y = 340 ----------------(II)
2) We can use elimination method to solve this equations.
Multiply equation (I) by (-20) and then add the equations.
(I)* (-20) -20x -20y = - 300
(II) <u>20x + 25y = 340 </u> {Now add and x will be eliminated}
5y = 40
y = 40/5
y = 8
Substitute y = 8 in equation (I)
x + 8 = 15
x = 15 - 8
x = 7
3) Number of dark chocolate bars = 8
Answer: 6
Step-by-step explanation:
Answer:
D) -1.8, -1 1/2 , 0.3 , 3/4 , 1
Step-by-step explanation:
Change all of the given terms to either fractions or decimals. Generally decimals are easier:
3/4 = 0.75
-1.8 = -1.8
1 = 1.0
-1 1/2 = -1.5
0.3 = 0.3
Order from least to greatest:
-1.8 , -1.5, 0.3 , 0.75 , 1.0
or
-1.8, -1 1/2 , 0.3 , 3/4 , 1
~
The number of terms in the expression is 2
