 The ratio of the number of cars to the number of motorcycles in a parking lot is 10:3. The ratio of the number of motorcycles t
serg [7]
I'll do this step-by-step. Note, ratios are basically division signs.

The ratio of cars to motorcycles in a parking lot is 10:3, which means there are 10 cars for every 3 motorcycles.

The ratio of motorcycles to vans is 2:3, there are 2 motorcycles for every 3 vans.

There are 30 vans, so there are 20 motorcycles, since 20 motorcycles:30 vans is equal to 2 motorcycles: 3 vans in fractions. (20 / 30 = 2 / 3)

So, the ratio of cars represented by x to the number of motorcycles, 20 can be written as x / 20 = 10 / 3. 10 / 3 is 3.333, meaning 3.333 cars per 1 motorcycle, so multiply 20 by 3.333 to get x, which is 66. There are 66 cars and 30 vans, so there are 33 more cars than vans in the parking lot. 66/20 = 10/3, both have a ratio of 3.33 when divided.

If you don't want the explanation, there are 33 more cars than vans in the parking lot.

All real numbers less than or equal to 9 and greater than or equal to 7 please hurry​
VashaNatasha [74]

Answer:

7 \leq x \leq 9

Step-by-step explanation:

Let x represent the real numbers.

For the first part, all real numbers less than or equal to 9 in algebra is x \leq 9.

For the second part, all real numbers greater than or equal to 7 in algebra is x \geq 7.

To combine both inequalities, it would become 7 \leq x \leq 9.

Hope this helped! If not, please let me know! <3
