Algebra what is 7×m = 420 what is the m?
2 answers:
7*m==420 7m=420 (divide by 7 on both times) m=60 hope that helps!
We need 7, m times to make 420, so If we divide 420 in equal groups of 7 we will get how many m will have. m=420/7=60

Answer:
L= 24cm
W= 4cm
Step-by-step explanation:
Given data
Perimeter= 56cm
Area= 96cm^2
Let the width be x
W= x cm
L= 5x+4
P=2L+2W
56= 2(5x+4)+2x
56= 10x+8+2x
56-8= 12x
48= 12x
x= 48/12
x= 4cm
L= 5x+4
L= 5(4)+4
L= 20+4
L= 24cm
