Question: -0.5, -0.67, -2/3, -13/20, -17/25
Answer: = −19
/6
Answer:
45+3 = 6=N
48_6= N
42= N
:. N= 42
Step-by-step explanation:
:. N= 42
Because the perimeter is all the sides added:
P = side + side + side
4x + 3y = x + y + x + y + s
2x + y = s
Hope this helps!
Answer:
757.35
Step-by-step explanation:
1. We assume, that the number 891 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 891 is 100%, so we can write it down as 891=100%.
4. We know, that x is 85% of the output value, so we can write it down as x=85%.
5. Now we have two simple equations:
1) 891=100%
2) x=85%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
891/x=100%/85%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 85% of 891
891/x=100/85
(891/x)*x=(100/85)*x - we multiply both sides of the equation by x
891=1.1764705882353*x - we divide both sides of the equation by (1.1764705882353) to get x
891/1.1764705882353=x
757.35=x
x=757.35
now we have:
85% of 891=757.35
