Answer:
1= -4a+7b
2=(7x-5)/3
Step-by-step explanation:
1,
a+3b-(5a-4b)
expand bracket 1st according to BIDMAS
a+3b-5a+4b
collect like terms
a-5a+3b+4b
ans=-4a+7b
2,
X/3+2x-5/3
solve for the 1st two
X/3 +2x
LCM =3 so,
(x+6x)/3=7x/3
use this and solve the last part
(7x/3)-(5/3)
LCM=3
ans=(7x-5)/3
Answer:
"c" b=p×s
Step-by-step explanation:
we are trying to find what b is .
so we can eliminate answers A & B
to find how many seeds are in a box we have to multiply how many packets there are by how many seeds are in a packet
example if there are 10 packets & you have 5 seeds in each packet then you would have 50 seeds in one box
B=p×s
B=10×5
B=50
Answer:
1. 4in wide
2. 5in tall
3. 10/6in (Equal to 1 4/6in)
4. 1in
5. 1in
I'm pretty sure these answers are right. Hopefully this helped. :)
We have to see how many times 55 pence fits into 3 Pounds:
3/0.55=?
if we multiply both numbers by 100, so that there are no fractions, we have:
300/55=5 and 25 cents left
(check: 5*55=275)
so the correct answer is 5 yoghurts.
