If a car averages 23.2 miles per gallon of gasoline, how far can it go on 15.25 gallons?
ankoles [38]

The car goes 23.2 miles every gallon, so with 15 gallons (15 * 23.2 = 348) it can go 348 miles. With the extra .25 that the car has, it can go 0.25 * 23.2 = 5.8 miles. 348 miles plus the 5.8 miles gets you 353.8 miles on 15.25 gallons.

What is the least common denominator for the fractions1/6and 3/4 ?
melomori [17]
A. 12; Least common denominator is the least multiple that the denominator have together. So you multiply the denominators until you get the first number they both have in common.
6*1 = 6
6*2 =12

4*1 =4
4*2 =8
4*3 = 12 

Since the first number they both have in common is 12, the least common denominator is 12

Answer:

x = 30

Step-by-step explanation:

Since this is a right triangle,

90 = (x + 20) + (x + 10)

90 = x + x + 20 + 10

90 = 2x + 30

90 - 30 = 2x

60 = 2x

60/2 = 2x/2

30 = x

Check:

x + 20

30 + 20 = 50

x + 10

30 + 10 = 40

50 + 40 = 90

Hope this helps!

I would seriously appreciate if u helped me TvT

Answer:

x=-11

Step-by-step explanation:

So we have the equation:

5+(x-2)=-8

Let's subtract 5 from both sides:

(5+(x-2))-5=(-8)-5

The left side will cancel. Subtract on the right:

x-2=-13

Now, add 2 to both sides:

(x-2)+2=(-13)+2

Again, the left side will cancel. Add the right:

x=-11

And we're done!
