Answer:
D) CE=10
Step-by-step explanation:
FG=6x-7
CE=18-4x
2FG=CE
2(6x-7)=18-4x
12x-14=18-4x
simplify
16x=32
x=2
substitute
CE=18-4(2)
CE=18-8
CE=10
Answer:
B. D. E
Step-by-step explanation:
Answer: Shana bought 2 sodas.
Shana bought 5 bags of popcorn.
Step-by-step explanation:
Let S represent the number of sodas that Shana bought.
Let B represent the number of bags of popcorn that Shana bought.
Shana bought 7 things from the concession., all either sodas or bags of popcorn. This means that
S + B = 7
Sodas cost $3 each and popcorn cost $4 per bag. Shana spent a total of $26. This means that
3S + 4B = 26 - - - - - - - - - - - - -1
Substituting S = 7 - B into equation 1, it becomes
3(7 - B) + 4B = 26
21 - 3B + 4B = 26
- 3B + 4B = 26 - 21
B = 5
S = 7 - B = 7 - 5
S = 2
Any number greater than 700,000 with ten-thousands digit 1 through 4 will round down to 700,000. For example, 748,235 will round to 700,000.
