40 minutes is 2/3 of an hour.

30 miles per hour x 2/3 hour = 20 miles.

30 minutes = 1/2 hour.

60 miles per hour x 1/2 hour = 30 miles.

Total = 20 + 30 = 50 miles.

1/4 = 2/8. Remember that. This means that 1/8 is equal to half of a month. It there is 5/8, you can add a half month for every eight. In this case, it will take 2 and a half months

Solve and graph: 7x-6&gt;22<br>(pls explain your answer, im confused on this)​
grandymaker [24]

Answer:

x>4

Step-by-step explanation:

Solving an inequality is very similar to solving an equation:

Given: 7x-6>22

Add 6 to both sides: 7x>28

Divide both side by 7: x>4

x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.

Can someone please help me
kaheart [24]

Answer:

3x+2y <=30

3x represents the roses, because each rose is 3 dollars. 2y represents the carnations, because each carnation is 2 dollars. The total amount of money spent (3x+2y) should be less than or equal to 30 dollars, since the problem says that she does not want to spend more than 30 dollars.

Hope this helps!
