Answer:
458 cm²
Step-by-step explanation:
5 × 5 × 2 + 5 × 18 × 4 = 50 + 360 = 410
2 × 2 × 4 × 3 = 48
410 + 48 = 458
Answer:
6
Step-by-step explanation:
27/4= 6 3/4
That doesn't work because we need whole numbers.
24/4=6
That is the solution. For $24 we buy 6 tubes for $4 each and we have $3 left over.
Answer:
The price before vat is 1,425
Step-by-step explanation:
I. When total price = price + vate*price
So 1,539 = x + 0.08 + x => when 0.08 is 8/100 or 8 percent
1,539 = 1.08x
x = 1,539/1.08
x = 1,425
II. Prove by replace x.value with 1,425
1,539 = 1,425 + 0.08(1,425)
1,539 = 1,425 + 114
1,539 = 1539 true
Hope that help :)
Well here is how you do it. you take 84 and estimate the ones place and do the same with 18. since 18 has a big number above 5 or more we raise the score. not to 19, but 20. The 4 in 84 is lower so it stays the sames. we don't keep it as 84 we change the number by taking out 4 and placing a zero. Now all we need to do is do the math. 80 - 20 = 60.
