Answer:

b. 60

Step-by-step explanation:

We have been given a formula 5x+10y=800, where x represents the number of small vehicles and y represents the number of larger vehicles.

To find the number of small vehicles, we will substitute y=50 in the given equation as:

5x+10(50)=800

5x+500=800

5x+500-500=800-500

5x=300

\frac{5x}{5}=\frac{300}{5}

x=60

Therefore, 60 small vehicles were washed in total and option 'b' is the correct choice.

The Tonga Trench is at an elevation of 35,702 feet below sea level. The South Sandwich Trench is at an elevation of 23,737 feet
Svetach [21]

Both elevations or numbers are already expressed as a rational number. This is because a rational number is defined as a number that can be expressed as a quotient or fraction of two numbers:

p / q

Since in this case, q may be equal to 1, then both are rational numbers.

A map uses a scale of 3/4 in = 80 miles. If two buildings are 60 miles apart in real life, how far apart would they be drawn on
Alla [95]

Given:

The scale of a map is \dfrac{3}{4}\ in=80\ miles.

The distance between two buildings is 60 miles.

To find:

The distance between the given building on the map.

Solution:

We have,

\dfrac{3}{4}\ in=80\ miles

It means, 80 miles in real life = \dfrac{3}{4}\ in on the map.

1 mile in real life = \dfrac{3}{4\times 80}\ in on the map.

60 mile in real life = \dfrac{3\times 60}{4\times 80}\ in on the map.

                              = \dfrac{180}{320}\ in on the map.

                              = \dfrac{9}{16}\ in on the map.

Therefore, the buildings are \dfrac{9}{16}\ in apart on the map.
