Answer:
40 bottles of juice
60 bottles of water
Step-by-step explanation:
let w represent water, let j represent juice. set up a system of equations:
w+2j=140
w+j=100
isolate the w by itself on the bottom equation:
w=100-j
solve the top equation by substitution, substituting 100-j for w:
w+2j=140
100-j+2j=140
100+j=140
j=40
this means that they bought 40 bottles of juice.
to find the amount of bottles of water the bought, substitute 40 for j in either of the equations (i did it in the bottom one, because it's easier):
w=100-j
w=100-40
w=60
so, they bought 60 bottles of water.
Answer:
Step-by-step explanation:
Given
- A is between C and T
- CA =4x + 6
- AT =7x-6
- CT =132
As per segment addition postulate:
- CT = CA + AT
- 4x + 6 + 7x - 6 = 132
- 11x = 132
- x = 132/11
- x = 12
Answer: Yes
