Answer:
7
Step-by-step explanation:
We are to solve 4.2÷0.6 using base 10 blocks
4.2 = 42/10
0.6 = 6/10
4.2÷0.6
= 42/10 ÷ 6/10
= 42/10 * 10/6
= 42/6
= 7
Hence the required expression using base 10 block is 7
a = -1 and b = 5
5a-7b+b2
5(-1) - 7(5) + 5^2
-5 - 35 + 25
-40 + 25
-15
-15 would be the result

The price of the product before promotional sales was 500,000.
<h3>How to find out what the previous price was?</h3>
To find what the previous price of the product was, we must take into account that we know that 87% of the value is equal to 435,000. So to find out how much the 13% (discount) that the product had is equivalent to, we do the following operation:
435,000 × 100 ÷ 87 = 500,000
So we know that the 13% discount was 65,000
