Answer:
The answer is 80.
Step-by-step explanation:
Firstly we add all of the stamps
118+83+4=205
She put 125 in first album so we have
205-125=80 stamps left
These 80 she needs to put in another album
Answer:
10x+5y=2
Step-by-step explanation: You have the equation 10x+5y=1 and from the problem, we are trying to find an equation that does not produce a solution with 10x+5y=1. To do this know 1 is your y-intercept and if you put 10x+5y=1 into slope-intercept form you'll get y=-2x+1/5. Solve the problem know that you can use any number besides 1 on the right side and have the same slope to fit the question. What I mean is that let's say I have 10x+5y=2, I put it into a slope-intercept form I'll have y=-2x+2/5. The two equations y=-2x+1/5 and y=-2+2/5 will not meet because their slopes are PARALLEL. So in short have a different y-intercept but the same slope to not get a solution. Additional note you could have other y-intercepts such as 3,4,5,6,7,8, or 9 in your standard form equation 10x+5y= to get a equation that does not make a solution with 10x+5y=1.
Answer:
C. $240 for 4.5 days.
Step-by-step explanation:
Let's find the answer using the following data:
Notice that the first day is $88 which can be written as:
first day= $38 + $50, in this way the first day cost the same as the other additional days but it include an additional $50 charge.
In this way we can have the formula:
S(x)=38x+50
Notice in the above formula that the '50' represents the extra money for the first day, while '38' the normal cost per day.
Now, S(4.5) needs to be evaluated as S(5) given the condition that a partial day also costs $38, so:
S(4.5)=S(5)=(38*5)+50=240
In conclusion, for 4.5 days the cost is $240, so de answer is C.
