Answer:
The area of the triangle is 168 meters
Step-by-step explanation:
<u>Formula to find the area of a triangle:</u>
<em>Area = 1/2 Base x Height</em>
<u>So, first you need to identify the base and the height. The base is 16m + 8m, and the height is 14m. All you have to do is plug in the numbe</u>rs:
Area = 1/2 (16 + 8) x 14
<u>Then, you solve:</u>
Area = 1/2 (16 + 8) x 14
Area = 1/2 24 x 14
Area = 1/2 336
Area = 168 meters
So, the area of the triangle is 168 meters

Answer: the efficiency of the first car is 25 miles per gallon.
the efficiency of the second car is 30 miles per gallon.
Step-by-step explanation:
Let x represent the efficiency of the first car.
Let y represent the efficiency of the second car.
Distance = car efficiency × number of gallons.
The first car consume 25 gallons of gas and the second consumed 15 gallons of gas. The two cars Drove a combined total of 1075 miles. It means that
25x + 15y = 1075- - - - - - - - - - -1
The sum of the fuel efficiencies was 55 miles per gallon. It means that
x + y = 55
Substituting x = 55 - y into equation 1, it becomes
25(55 - y) + 15y = 1075
1375 - 25y + 15y = 1075
- 25y + 15y = 1075 - 1375
- 10y = - 300
y = - 300/-10
y = 30
x = 55 - y = 55 - 30
x = 25
Answer:
x = 2 because 5 times 2 = 10 and 10 - 2 = 8
