The greater common divisor between 10 and 15 is 5, so we can factor it out:

$10x^2-15x = 5(2x^2-3x)$

The greater common exponent between 1 and 2 is 1, so we can factor x out:

$10x^2-15x = 5x(2x-3)$

Answer: -418, 728, 446, -429, 1159, -696

Step-by-step explanation:

1. $n = -199 - 219 = \boxed{-418}$ .

2. $m = 438 - (-290) = 438 + 290 = \boxed{728}$ .

3. $128 - (-318) = 128 + 318 = \boxed{446}$ .

4. The sum of 429 and 429 is $429+429 = 858$ . We need to subtract this from 429, so $429 - 858 = \boxed{-429}$ .

5. The sum of 510 and 319 is $510+319 = 829$ . Subtracting -330, we get $829 - (-330) = 829 + 330 = \boxed{1159}$ .

6. Call the unknown number " $\star$ ". Then $\star + 298 = -398$ , so $\star = -398 - 298 = \boxed{-696}$ . (Think about it.)

“The perimeter P of a triangle is equal to the sum of the lengths of sides a,b, and c”

Kryger [21]

Answer:

1. Write the addition of "a", "b" and "c".

2. The equation is: $P=a+b+c$

Step-by-step explanation:

You know that P represents the perimeter of the triangle and a, b and c represent the sides of the triangle.

By definition, the sum is the result of an addition. Therefore, the statement "The perimeter P of a triangle is equal to the sum of the lengths of sides a, b, and c”, indicates that the perimeter is obtained by adding the lengths of the sides of the triangle.

Knowing this, you can write the following equation:

$P=a+b+c$

An oil company fills 1 over 12 of a tank in 1 over 3 hour. At this rate, which expression can be used to determine how long will

Leto [7]

Don't let fractions fool you.

$\frac{1}{12}$ of a tank in $\frac{1}{3}$ an hour is equal to:
1/12 of a tank in 20 minutes.

Thus we know in an hour, an oil company can fill 3/12 of a tank (60 minutes in an hour).

3 x 4 = 12, and 12/12 = 1(a whole tank), so we multiply 1 (hour) by 4.

Our answer is that it takes 4 hours to fill a tank.

A mule dear can 1/4 of a mile in 25 seconds. At this rate, what expression can be used to determine how fast a mule deer runs in

Naddika [18.5K]

We have to find how many seconds are in one hour.
There are 60 seconds in one minute, with 60 minutes in every hour.
60×60=3600
Now, see how many 25 seconds are in 3600 seconds.
3600÷25= 144
Now, we can multiply 144 by 14 or .25 since we are trying to find per hour.
144×.25= 36
36h
H being the hours you're trying to find. It runs 36 miles per hour.
