Answer:
hi
Step-by-step explanation:
4- 3*1=3
6*1/100= 0.06
3+0.06= 3.06
5- 7*1= 7
3*1/10= 0.3
4*1/1,000= 0.004
7+0.3+0.004= 7.304
7- 3.3, 3.30
8- 9.3000, 9.30
9- 9.6, 9.600
10- 4.4000, 4.40
for #4-5 just put the number of 0s in the denominator of the fraction for the answer

Step-by-step explanation:
51.78 is rounded up to 52
The perimeter for this rectangle is: 276
Answer:
Step-by-step explanation:
1) First, find the slope of the line by using two points on the graph. We can see that (0,5) and (4,0) are clearly marked on the line, so let's use those points. Use the slope formula 
and substitute the x and y values of those points into it, then simplify:
So, the slope is 
.
2) Now, identify the y-intercept on the graph. The y-intercept is the point at which the line intersects the y-axis. By reading the graph, we can see that the line intersects the y-axis at (0,5), so that must be the y-intercept.
3) Substitute values for 
and 
in the slope-intercept formula, 
, to write the equation of the line. Since represents the slope, substitute for it. Since represents the y-intercept, substitute 5 in its place. This gives the following answer and equation in slope-intercept form:
You're first problem is unclear as I am not sure if that t was suppose to be there or not.
but as for the second one (33.7y+8.4-2.04y) we would first have to combine like terms so you'd subtract 2.04y from 33.7y , which would give you ; 33.66y so now your answer would be " 33.66y + 8.4 ",
there's nothing more you can do because they're seperate terms c: .
Your third problem ( 4.2x+8.1x+1.8x-2.1x ) is also combining like terms. Add the first 3 terms and that'll give you 14.1x , now subtract 2.1x and that'll give you "12x" as your final answer ~
For your fourth problem x+2 ( x-y ) , you would have to do something called factoring , basically all you gotta do is distribute term by term. So, x times x would give you x^2 , x times -y would give you -xy , 2 times x is 2x , and 2 times -y is -2y , so that'll look somethng like x^2 - xy + 2x - 2x . Now the 2x's cancel out
and you are left with "x^2 - xy" as your final answer ~
