Answer:
1. 5/4
2. 7
Step-by-step explanation:
1) Lets call the width as w
Therefore length would be:
w+4
To find the perimeter you use the formula:
2 (l+w)
Now substitute our values into this formula:
2 (w+4+w)
2( 2w+4)
4w+8
Now make this equal to 13:
4w +8 = 13
4w = 5
w = 5/4
2. In this question we will call length l
Therefore width would be:
l-5
Now we will do the steps we did above:
2 (l+l-5)
2 (2l-5)
4l -10
4l - 10 = 18
4l = 28
l = 7
Answer:30,41,66
Step-by-step explanation:
(X+7)+(2x-5)+(3x-3)=137
Solve for x
X=23 cm
Sides are 23+7=30
2*23-5=41
3*23-3=66
It would take her 2 hours
Answer:
If you meant what is 1/10 of 80 the answer is 80
Step-by-step explanation:
Multiply 45 by 1/5, or 0.2, and you will get an answer of 9, which is the amount of tulips that were yellow. You will know that you need to multiply 45 by either 1/5 or 0.2 because you can make a fraction 20/100 and simplify it to 1/5, or you can move the decimal point in 20.% two times to the left getting the decimal to divide the amount of tulips by
