3/4

Write the proportion formula like this: P(event) For this problem you would write it like this: P(pick red) Since there are 4 blocks (two red and two blue) there is a 1/2 chance that you would pull out a red block.

Hope this helps!

What are the points for -3x+6y+5=-7

Novay_Z [31]

-3x + 6y + 5 = -7
 -5 -5
 -3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
6y = -12 + 3x
6 6
y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
-3x - 12 + 3x = -12
-3x + 3x - 12 = -12
0x - 12 = -12
 +12 +12
 0x = 0
 0 0
 x = 0
-3(0) + 6y = -12
0 + 6y = -12
+0 +0
 6y = -12
 6 6
 y = -2
(x, y) = (0, -2)

5x-8=37 find the value of x

Andrej [43]

Because −8 does not contain the variable to solve for move it to the other side of the equation by adding 8 to both sides.
5x=8+37

Add 8 and 37 to get 45.
5x=45

Divide each term by 5.
x=9


x is equal to 9

What is the number sentence for "1 less than N is the sum of Z and 2"?

s344n2d4d5 [400]

$\rule{50}{1}\large\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}$

What is the number sentence for "1 less than n is the sum of z and 2?"

$\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}$

❖ First, Notice it says "1 less than n". This expression indicates that

we subtract 1 from n, which looks as follows:-

$\Large\textit{n-1}$

❖ Now, It also says "the sum of z and 2". This indicates that we add z and

2:-

$\Large\textit{z+2}$

❖ Now, Combine these two little expressions into one equation:-

$\implies\sf{n-1=z+2}$

<h3>Good luck with your studies.</h3>

Ms. Daffy tells you that the longest side of her right-triangular garden is 26m and one of the sides is 14m. A. She asks you to

ira [324]

Answer:

22m

Step-by-step explanation:

The computation is shown below:

Since it is a right-triangular garden so we use the pythagoreus theorem

As we know that

The C^2 refers to the longest side of the right-triangular garden

So,

a^2 + b^2 = c^2

a^2 + 14^2 = 26^2

a^2 + 196 = 676

a^2 = 480

So a = 22m

Hence, the other side of the garden is 22m

The sum of three consecutive even integers is -78. What is the smallest integer? Show all working outs (5)

svet-max [94.6K]

Answer:

The smallest integer is -27 and the integers are -27, -26, and -25

Step-by-step explanation:

We can represent this with:

x + x - 1 + x - 2 = -78

Simplify.

3x - 3 = -78

Add 3 to both sides.

3x = -75

Divide both sides by 3.

x = -25

So, the first integer is -25.

Subtract two to get the smallest integer.

-25 - 2 = - 27
