78
because 5 times 2 equals 10 so then u times 39 times 2 and get 78
the answer to the question is F= -5.37
Answer:
Q. 2)Perimeter =2(l+b)
So,
2(8x-8 +8x)=80cm(Given in Question)
= 2*16x-8=80cm
16x- 8= 80 divided by 2,
16x=40+8=48
x=48 divided by 16
X=3
Q.1) Perimeter=2(l+b)
2(2x+8 +4x)=76cm(Given in Question)
2* 6x +8=76
6x+8= 76 divided by 2, 38
6x= 38-8, 30
x= 30 divided by 6 = 5
X=5
THANK ME LATER
2% of 300 would be 6 and 6 rounded to the nearest 100th is 6.00
X + Y = 18
X=chickens, Y=Cows
2x + 4y = 60
Let's try 8 and 10.
16 + 40=56, no, 32+20=52, no. 8&10 do not work.
Let's try 9 and 9.
18+36=54, no. 9&9 do not work.
Let's try 11 & 7.
22+28=50, no. 14+44=58, no.
Let's try 12 & 6.
24+24=48, no. 12+48=60 YES!
There are 12 cows and 6 chickens.
