Add x to the -4x then subtract the 13 to 1, 13 and 13 cancels out leaving you with -4x=-12 then you divide -4 to -12 and you end up with x=3

Find the lengths of the missing sides in the triangle. Write your answers as integers or as decimals rounded to the nearest tent

Fantom [35]

Answer:

y = 8

x = 11.3

option 2

Step-by-step explanation:

We can recognize this right triangle as a special triangle, a 45° - 45° - 90° triangle more specifically. This triangle would be isosceles because the two base angles are both 45°. Since the triangle is isosceles, we can say that the legs are congruent, so y = 8. In a 45° - 45° - 90° triangle, the hypotenuse is √2 times the legs. To find x, we can set up the equation:

8 * √2 =x

x = 8√2 or about 11.3

Consider all four-digit numbers that can be made from the digits 0-8 (assume that numbers cannot start with 0). What is the prob

vodomira [7]

Answer:

0.2498

Step-by-step explanation:

Number of 4 digit numbers that can be formed from the digit (0 - 8), assume number can't start from 0

Thus ;

First digit = (1, 2, 3, 4, 5, 6, 7, 8) = 8 ways

Next three digits = (0, 1, 2, 3, 4, 5, 6, 7, 8) = 9 ways

Hence,

Total possible outcomes = sample space = (8 * 9 * 9 * 9) = (8 * 9^3 ) = 8 * 729 = 5832

Required = number greater Than 7000

For number to be greater Than 7000, starting digit should be either 7 or 8

Hence,

First digit = 2 ways

Next three digits = 9 ways

Also excluding 7000

Hence, Number of digits above 7000;

2 * 9^3 = 2 * 729 = 1458 - 1 = 1457

Hence,

Probability = 1457 / 5832

= 0.2498285

= 0.2498

Help please!!<br> Solve for X.

Mekhanik [1.2K]

Answer:

3) x = 9

4) x = 3

Step-by-step explanation:

3) The two short segments are indicated as having a sum equal to the long segment.

(x +2) +(-5 +x) = 15

2x = 18 . . . . . . . . . . . . add 3

x = 9 . . . . . . . . . divide by 2

(This makes the segments be 9+2 = 11 and -5+9 = 4, which total 15.)

4) Same deal.

3x +3 = 4x

3 = x . . . . . . . . subtract 3x

(This makes the segments be 3(3) = 9 and 4(3) = 12, where 9+3=12.)

Sam's van travels 208.8 miles on 9 gallons of gasoline. Hasan's small car travels 234.4 miles on 8 gallons of gasoline. What is

poizon [28]

Answer:

The difference between the vehicles is 0,009 gallons per mile.

Step-by-step explanation:

To know the difference between the vehicles in gallons per mile we need to obtain this information for each car:

-Sam´s van

Gallons per mile: 9 gallons/208.8 miles

Gallons per mile: 0.0431

-Hasan´s small car:

Gallons per mile: 8 gallons/234.4 miles

Gallons per mile: 0.0341

The difference between the vehicles is:

0.0431-0.0341= 0,009 gallons per mile
