Answer:
Step-by-step explanation:
10m-2/5=9 and 3/5
10m-2/5=9.6 (where 9 and 3/5 is equal to 9.6)
50m-2=48 (i multiplied 10m by 5 and 9.6 by 5)
50m=50 ( i added 2 to both sides)
m=1 ( i divided by 50 to both sides to find m)
Answer:
The addition that matches the problem is the first one.
Step-by-step explanation:
The red line goes back 8 so it is a -8 and the blue line goes forward 4 so it is a postive 4.
4 + (-8) = -4
Answer:
1 : 80
Step-by-step explanation:
So you want to check Length of model : Length of real boat
50 cm : 40 m
But since the units don't match, make 40 m into 4000 cm
50 cm : 4000 cm
Divide both sides by 50 and you get
1 : 80
Answer:
3(n-5)=2n+16
Step-by-step explanation:
3 lots of 'n' <em>and </em>5 means 3 times both values so these values are put into a bracket with a common multiplier (ie. the 3)
3(5 - n)
16 more than 2 lots of 'n' means that n has to be doubled. n + n = 2n. add 16 to this and we have
2n + 16
if these values are both equal (hence why they are in an equation) then all that is needed is for them to be set equal alongside each other.
3(n-5) = 2n+16

The volume is 336 cubic feet
6x8x3 = 144
8x4x6= 192
144+192=336
