Positive 14/472 (because of rise over run when finding slope)

Info:

Use rise over run when finding slope

U can solve by yourlsf by knowing:'

"A line with a positive slope (m > 0), as the line above, rises from left to right whereas a line with a negative slope (m < 0) falls from left to right. A line with the slope zero (m = 0) is horizontal whereas a line with an undefined slope is vertical. ... You can interpret a slope of a line as the rate of change."

Answer:

+14/472

Montel collected 26 leaves for his science project. he wants to put 6 leaves on a page. which shows how many pages montel will n

MissTica

You divide 26 by 6, and you get 4 1/3, so I guess Montel will need 5 pages.

After simplifying, which expressions are equivalent? Select three options.

Wewaii [24]

Answer: Second option, third option and fifth option.

Step-by-step explanation:

In order to solve this exercise it is important to remember the multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

Knowing that, you can distribute the sign and add the like terms. Repeat this procedure in each expression given in the exercise.

Therefore, you get:

$a.\ (3.4a - 1.7b) + (2.5a - 3.9b)=3.4a - 1.7b + 2.5a - 3.9b=5.9a-5.6b\\\\b.\ (2.5a + 1.6b) + (3.4a + 4b)=2.5a + 1.6b + 3.4a + 4b=5.9a+5.6b\\\\c.\ (-3.9b + a) + (-1.7b + 4.9a)=-3.9b + a -1.7b + 4.9a=5.9a-5.6b\\\\d.\ -0.4b +(6b - 5.9a)=-0.4b +6b - 5.9a=6b-6.3a\\\\e.\ 5.9a - 5.6b$

You can identify that the expressions $(2.5a + 1.6b) + (3.4a + 4b)$ , $(-3.9b + a) + (-1.7b + 4.9a)$ and $5.9a - 5.6b$ are equivalent after simplifying.

The sum of two consecutive even integers divided by four is 189.5

Andre45 [30]

The sum of two consecutive even integers is a+(a+2) and divided by four is
(a+(a+2))/4 = 189.5
(2a+2)/4 = 189.5
2a+2 = 189.5 * 4
2a+2 = 758
2a = 758 - 2
2a = 756
a = 756/2 = 378
first number is a = 378
second number is a+2 = 378+2 = 380

A cube has side length a. The side lengths are decreased to 50% of their original size. Write an expression in simplest form for

vaieri [72.5K]

Answer:

V = a³/8

Step-by-step explanation:

The volume of the original cube is the cube of the side length:

V = a³

When the side length is reduced to half its former value, the new volume is ...

V = (a/2)³ = a³/2³

V = a³/8 . . . . volume of the new cube
