Answer:
there are 40% black ball a
white ball we don't know
so, we let = x
40\100 × x
now we cutting
ans is 10x
Answer:
Yes
Step-by-step explanation:
If she is reading 20 pages a day, and needs to read 10 pages, then she needs half a day, and since she has 6 days, she can do this.
You have to think about the equation in y=mx+b form and since b (the y intercept) is 121 that is your answer.
The length of rectangle is 44 yards and width of rectangle is 20 yards
<em><u>Solution:</u></em>
Let the length of rectangle be "a"
Let the width of rectangle be "b"
<em><u>Rectangle has a length that is 4 more than twice the width</u></em>
Length = 4 + 2(width)
Length = 4 + 2b
The perimeter is 128 yards
<em><u>The perimeter of rectangle is given by:</u></em>
Perimeter = 2(length + width)
128 = 2(4 + 2b + b)
128 = 2(4 + 3b)
Divide both sides by 2
64 = 4 + 3b
3b = 60
b = 20
<em><u>Substitute b = 20 in length</u></em>
Length = 4 + 2(20)
Length = 4 + 40 = 44
Thus length of rectangle is 44 yards and width of rectangle is 20 yards
A , because you have to divide it so you can get the correct answer
