Abigail”s car used 9 gallons of gas to travel 378 miles. How many gallons of gas would she need to travel 210 miles?
pochemuha

Answer: 5 gallons

Step-by-step explanation:

First, we need to know how many miles we can get by on a gallon of gas. To find this, we need to divide 378 miles by 9 gallons.

378/9 = 42

42 miles per gallon.

Now, we need to find how many gallons of gas it will take Abigail to travel 210. To find this, we simply divide 210 by 42.

210/42 = 5

It will take Abigail 5 gallons of gas to travel 210 miles.

Right triangle EFG and right triangle EHG overlap as shown below. Angle HEG measures 35° and angle FGE measures 30°.
lesantik [10]

Given:

Triangle EFG and EHG are two right triangles.

m\angle HEG=35^\circ

m\angle FGE=30^\circ

To find:

The values of x and y.

Solution:

In triangle EFG,

m\angle EFG+m\angle FGE+m\angle FEG=180^\circ        [Angle sum property]

90^\circ+30^\circ+(x+35)^\circ=180^\circ

(x+155)^\circ=180^\circ

x+155=180

x=180-155

x=25

In triangle EHG,

m\angle EHG+m\angle HEG+m\angle EGH=180^\circ        [Angle sum property]

90^\circ+35^\circ+(y+30)^\circ=180^\circ

(y+155)^\circ=180^\circ

y+155=180

y=180-155

y=25

Therefore, the value of x is 25 and the value of y is also 25.
