Answer:
Width: 85 yards
Length: 95 yards
Step-by-step explanation:
Ok, so we need to make an equation for this problem. Let's call the width, w. We know that the length is 10 more than the width, so we can call it w +10.
180 = w + w + 10
Now, i order to isolate the w's we need to subtract 10 from each side.
170 = 2w
Now, we just have to divide by 2 on both sides.
W = 85
So we now know that the width is 85 and because the length is 10 more, the length is 95 yds.
Joe jumped the farthest at 6 1/4 (6 ft 3 in)
Chelsey jumped the shortest ar 4 1/5 (4 ft 2.4 in)
6-4=2
3-2.4=.6
the difference is: 2 ft and 0.6 in
Answer:
Michael is 21 years old while Jean is 7 years old.
Step-by-step explanation:
Given that Micheal is three times as old as Jean, but in seven years he will be twice old as she will be, to determine how old are they both at this time, the following calculation must be performed:
M = 3J
M + 7 = 2J + 7
7 = 1/3
7 x 3 = 21
21 + 7 = 28
7 + 7 = 14
21 / 7 = 3
28 / 14 = 2
Therefore, Michael is 21 years old while Jean is 7 years old.
Answer:
2500
Step-by-step explanation:
a² + 2ab + b²
49² + 98 + 1
Comparing terms
a²= 49²
a= 49
2ab = 98
2× 49 × b = 98
98b = 98
b= 98/98
b = 1
or
b²= 1
b=√1
b= 1
a=49 and b= 1
Hence (a+b)²= (49+1)²
50²= 2500
