Answer:

The solution for x would be 4.

Step-by-step explanation:

2x - 1 = 7

The value of x is unknown, but you do know that you are multiplying 2 by x. So, if you rewrite the equation as 7+1=2x, you know that 8=2x. If you then divide both sides by 2, you're left with 4=x which would mean that the variable x has a solution of 4

andrew11 [14]

Answer:

5.50x + 2y ≤ 18

Step-by-step explanation:

Romona has a total of $18 and she has to spend it on dog food.

Dry god food cost $5.50 per bag and wet dog food cost $2.00 per can.

We have to write an inequality to show the above condition.

Let the number of dry and wet dog food she buys be x and y.

The total cost of dog food must be less than $18.

Then,

5.50x + 2y ≤ 18

This is the required linear inequality.

Find the number if 5/6 of it is 55.
kow [346]

Answer:

The unknown number is 66.

Step-by-step explanation:

We know that we need to find the number that is 55 when calculated as 5/6 or the whole number. First, we must divide 55 by 5.

55 ÷ 5 = 11

This means that 1/6 of the unknown number is 11.

Now, let's multiply 11 by 6.

11 x 6 = 66

Therefore, the unknown number is 66.

Hope this helps! :)
