First, you should find a common denominator:
Turn 2/5 into 4/10 by multiplying by 2.
Then, find the difference in your fractions:
7/10 - 4/10 = 3/10.
Your answer is 3/10.
Since 4 nights cost $356, 356÷4=89, so one night costs $89. 7-4=3, so 89×3 is 267. 267+356 is 623. The total cost for 7 nights would be $623
Answer:
169
Step-by-step explanation:
PEMDAS
Parenthesis first
Add -1 and -3 which is -4
Divide 24 by 6 which is 4
(4-2+5*3*-4÷4)^2
(4-2-15)^2
(2-15)^2
(-13)^2
Which is 169
Answer:
The question has a mistake
Step-by-step explanation:
11d+7c= 172.5
10d+7c= 155.8
By subtraction;
1d+ 0c = 16.7
1d = 16.7
11×16.7+7c=172.5
7c = 172.5-11*16.7
You will get a negative answer yet the cost cannot be negative.
