Given that 35.8 x 4.23= 151.434<br>write down a division sum with an answer of 423.

Nina [5.8K]

Answer:

151434/358 = 423

Step-by-step explanation:

Every product with non-zero factors can be written as an equivalent division relation.

a·b = c ⇒ a = c/b

Here, we have 35.8 × 4.23 = 151.434. This can be written as the equivalent ...

4.23 = 151.434/35.8

We can multiply this by 100 to get a division relation with a quotient of 423:

423 = 15143.4/35.8

If we want, we can move the decimal points another place to the right to get ...

151434/358 = 423

A college bookstore charges $60 for a yearly membership. The first book is free with membership and any book after that costs $7

brilliants [131]

Answer:

The equation representing Total money spend being as a member is $m = 60+7.6(b-1)$

Step-by-step explanation:

Given:

Memberships charges = $60

Cost of 1 book = $7.60

Let number of books be 'b'.

We need to find Total money 'm' spend yearly on buying books after becoming member.

Now we know that 1 book is free for a member.

Total money spend 'm' will be equal to Sum Memberships charges and Cost of 1 book multiplied by number of books bought yearly minus 1.

Framing in equation form we get;

$m = 60+7.6(b-1)$

Hence The equation representing Total money spend being as a member is $m = 60+7.6(b-1)$
