4/5z=16 solve equation (that's a fraction )

1 answer:

6 0

So we need to isolate the variable. In order to do that, we need to multiply both sides by 5/4.
Why? That's so that 4/5z will be canceled out when multiplied by 5/4 to get just z.
And so, we would get 20 as our answer.

Nookie1986 [14]

Answer:

Step-by-step explanation:

dentify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).

Input the values into the formula. This gives us (10 - 8)/(-2 - 3).

Subtract the values in parentheses to get 2/(-5).

Simplify the fraction to get the slope of -2/5.

Answer:

b. False

Step-by-step explanation:

First oval is a domain, second oval is a range.

hot dogs are sold in packages of 10 and hot dog buns are sold in packs of 8 Tommy wants to know the least number of packs of hot

enot [183]

Answer:

4 packs of hotdogs, 5 packs of buns

Step-by-step explanation:

In this case, we need to find the LCM, least common multiple, of 8 and 10 to find the least number of packs of hot dogs and buns that Tommy needs to buy.

The LCM of 8 and 10 is the smallest number that is both divisible by 8 and 10. One way we can find this is by checking all the multiples of 10 in ascending order to see if they are divisble by 8:

10 is not divisible by 8

20 is not divisible by 8

30 is not divisible by 8

40 is divisible by 8!

Therefore, Tommy will need to by 40 buns and 40 hotdogs. Since buns come in packs of 8 and hot dogs come in packs of 10, we can divide to get the number of packs Tommy should buy respectively:

$40$ ÷ $10=4$ packs of hotdogs

$40$ ÷ $8=5$ packs of buns

Tommy will need to buy 4 packs of hotdogs and 5 packs of buns so that he does not have anything left over.

I hope this helps! Let me know if you have any questions :)
