Answer:
n = 19
Step-by-step explanation:
22n = 418
Divide both sides by 22.
n = 19
Answer:
Step-by-step explanation:
x + y = 22
22 cards = 26
5(4) +y(2) = 26
20+2y = 26
20-20 +2y = 26-20
2y =6
2y/2 = 6/2
y = 3

Answer:
The length of the rectangular playing field is 177 yards and the width is 46 yards
Step-by-step explanation:
Let
x -----> the length of the rectangular playing field
x -----> the width of the rectangular playing field
we know that
The perimeter of the rectangular playing field is
P=2(x+y)
P=446 yd
so
446=2(x+y) ------> equation A
x=4y-7 -----> equation B
Solve the system by substitution
Substitute equation B in equation A and solve for y
446=2(4y-7+y)
223=5y-7
5y=223+7
5y=230
y=46
Find the value of x
x=4(46)-7
x=177
therefore
The length of the rectangular playing field is 177 yards and the width is 46 yards
